Whole House Generator Sizing Guide: How To Choose The Right Size For Your Home

Thu, 09 Apr 2026 09:23:50 GMT

Choosing the right standby generator for your home isn't as simple as matching wattage numbers. Whole-house generator sizing determines how much power your system needs to run essential appliances or your entire home during an outage. Selecting the wrong size can lead to system failure, equipment damage, or wasted money.

This guide from Southern HVAC walks you through real-world sizing, accurate calculations, and expert recommendations, helping homeowners in Hammond, LA, and across Southeast Louisiana confidently choose the correct generator size for their home.

Key Takeaways

Whole-house generator sizing requires calculating running watts, starting watts, and adding a safety margin.
HVAC systems are the largest power demand and must be prioritized in sizing.
Incorrect sizing leads to overload, inefficiency, or unnecessary costs.
Most homes require 15–26 kW, depending on size and usage.
Generators should operate below 80% capacity for optimal performance.

What Are The Power Requirements Of A Whole House Generator?

The total power demand of a home depends on which appliances and systems you need to run during an outage. The largest load in most homes is the HVAC system, which also creates the highest startup surge.

A typical central AC unit requires:

3,500 – 5,000 running watts
6,000 – 10,000 starting watts

A compressor creates a surge load through inrush current. This surge lasts 1–3 seconds during startup, but your generator must handle peak demand without a voltage drop.

Most central AC units draw 60–100 Locked Rotor Amps (LRA), making HVAC the most critical factor when sizing a whole-house generator.

Why Are Starting Watts Critical For Generator Sizing?

Starting watts determine generator capacity because compressors require a high inrush current. If the generator lacks surge capacity:

AC fails to start
Generator overloads or shuts down
Electrical components degrade faster

Starting watts enable operation, while running watts sustain continuous performance

Step-By-Step: How To Calculate Generator Size

Generator sizing requires adding the running load and the largest surge load, then applying a safety margin

Step 1: List Your Essential Appliances

Include only essential loads to reduce generator size:

HVAC system consumes the highest power
A refrigerator preserves food safety
Lighting circuits provide visibility
A well pump supplies water
Medical devices ensure continuity

Reducing non-essential loads lowers the required kW capacity.

Step 2: Calculate Total Running Watts

Add up the continuous (running) wattage of all selected appliances.

Step 3: Add The Largest Starting Surge

Include only the largest single surge load (typically AC or well pump).

Step 4: Apply A Safety Margin

Add 20–25% extra capacity to prevent overload and allow future expansion.

Prevents continuous 100% load operation
Supports additional appliances
Improves generator lifespan

Example Calculation

A typical 2,000 sq ft home in Southeast Louisiana with central AC, refrigerator, lighting, and a well pump:

Is Electric Heat Cheaper Than Gas? A Complete Cost Comparison

Thu, 26 Feb 2026 02:47:01 GMT

Electric heat versus gas heat costs vary by utility rates, climate zone, equipment efficiency, and home insulation levels. This guide from Southern HVAC provides a clear, data-driven comparison to answer “is electric heat cheaper than gas” , using real cost examples, efficiency ratings, and long-term operating projections.

Key Takeaways

Gas heat usually costs less in cold climates because natural gas delivers a lower cost per BTU during extended subfreezing temperatures.
Heat pumps cost less in mild climates because they transfer heat efficiently with a COP between 2.5 and 4.0.
Electric resistance heat costs the most to operate due to higher electricity rates per kWh.
Installation costs differ significantly, with electric furnaces typically costing less upfront than gas furnaces or heat pumps.
Local utility rates ultimately determine whether electric or gas heating delivers lower monthly and long-term costs.

Gas Vs. Electric Heating: How Each System Works

Understanding the core differences between types of heating systems helps clarify cost differences, efficiency expectations, and performance in different climates.

Gas Heating Systems

A gas furnace burns natural gas inside a sealed combustion chamber. Heat from combustion passes through a heat exchanger, and a blower distributes warmed air through ductwork into the home.

Efficiency measurement:

AFUE (Annual Fuel Utilization Efficiency)
Modern units: 80%–98% AFUE
A 95% AFUE furnace converts 95% of fuel into usable heat

Key attributes:

Requires a natural gas line and venting
Produces combustion exhaust
Lifespan: 15–20 years
Maintains full heating output in subfreezing temperatures

Electric Heating Systems

Electric heating systems operate through electric resistance heating or heat pump technology.

1. Electric Resistance Heating

Electric resistance systems convert electricity directly into heat.

Efficiency: ~100% at point of use
No combustion loss
Higher operating cost per BTU

Although electric resistance heat is technically 100% efficient inside the home, electricity generation and transmission losses occur at the power plant level and are not reflected in this rating.

2. Heat Pumps

Heat pumps transfer heat rather than generate it.

Efficiency metric: COP (Coefficient of Performance)
Typical COP: 2.5–4.0
COP 3.0 = 300% heat output relative to electricity input

Because heat pumps move heat instead of creating it, they can deliver more energy than they consume under moderate outdoor conditions. However, as outdoor temperatures drop below freezing, heat pump efficiency declines, and auxiliary heat may be required.

Installation Costs: Gas Vs. Electric Heating

Many homeowners researching “is electric heat cheaper than gas?” focus first on installation cost.

Electric resistance systems typically have lower upfront installation costs. Heat pumps typically cost more initially but may reduce long-term operating costs in mild climates.

Energy Bills: Is Gas Or Electric Cheaper Per Month?

Monthly operating costs depend on energy rates and system efficiency.

Note : The following example uses national average utility assumptions of approximately $0.15 per kWh for electricity and $1.30 per therm for natural gas. Actual costs vary by region.

In colder regions where heating demand is high and sustained, natural gas is typically cheaper per BTU.

In moderate climates where winter temperatures remain above freezing, high-efficiency heat pumps can compete with and sometimes outperform gas furnaces in operating cost.

According to the U.S. Energy Information Administration (EIA) , electricity prices fluctuate more significantly by region than natural gas prices, which can shift cost comparisons locally.

Maintenance Cost And Long-Term Heating Costs

Gas Furnace Maintenance

Gas furnaces require annual inspection because combustion components degrade over time. Technicians inspect burners, heat exchangers, safety controls, and venting systems to ensure safe operation.

Annual maintenance typically costs $120–$300 and reduces the risk of carbon monoxide issues and major repairs.

Electric Furnace Maintenance

Electric furnaces require less frequent servicing because they do not burn fuel. Maintenance focuses on heating elements, electrical connections, and blower motors.

With fewer combustion components, electric systems generally have lower annual maintenance costs.

Heat Pump Maintenance

Heat pumps require biannual service because they operate year-round for both heating and cooling. Technicians inspect refrigerant levels, coils, compressors, reversing valves, and electrical components.

Because heat pumps operate year-round, component wear may occur sooner than in single-season systems, potentially increasing long-term maintenance costs. If your system runs but does not deliver warm air as expected, learn why your heater may be blowing cold air and when it signals a system issue.

Which Heating System Is Best For Your Home?

The best heating system depends on measurable factors such as climate zone, local utility rates, home insulation level, square footage, and access to gas infrastructure.

When Electric Heat May Be Cheaper

Electric heat may cost less in mild climates where winter temperatures stay above 35°F. High-efficiency heat pumps with a COP above 3.0 significantly reduce cost per BTU.

Electric systems also become competitive when:

Natural gas prices rise above $1.80 per therm
Homes are well insulated with low heating demand
Duct losses are minimized
Local incentives favor electrification, or heat pump rebates, which reduce upfront cost

When Gas Heat May Be More Cost-Effective

Gas heat becomes more cost-effective in colder climates with extended subfreezing temperatures. Furnaces maintain a stable output regardless of outdoor conditions.

When natural gas costs fall below $1.20 per therm, gas systems typically deliver lower monthly heating costs, especially in larger homes over 2,500 sq uare feet with high heating demand.

Should You Switch From Gas To Electric?

Switching from gas to electric heating requires a technical evaluation of your home’s infrastructure and long-term energy costs.

Key considerations include:

Electrical panel capacity (often 200-amp service for heat pumps)
Duct compatibility
Insulation quality
Local utility rate trends
Total installation and labor costs

Improper system sizing can reduce efficiency by 10–20% and shorten equipment lifespan. A licensed HVAC professional should perform a full load calculation before recommending a change.

Why Professional Installation Matters

Proper system sizing improves efficiency by 10–20% and prevents premature wear. Incorrect installation can increase energy consumption, reduce comfort, and void manufacturer warranties. Licensed technicians ensure correct combustion setup, refrigerant charge accuracy, airflow balance, and manufacturer warranty compliance.

Gas furnaces typically operate between 80 and 98% AFUE efficiency , while electric resistance heaters convert electricity fully but cost more per kilowatt hour.

Higher heater energy usage also results from heat loss through walls, ceilings, and ductwork. Poor insulation in walls, attics, and duct systems can increase heating demand by up to 30% , raising overall energy costs.

Does Cooling Cost More Than Heating In Southern States?

Cooling costs more annually than heating in southern states because air conditioning runs for longer periods each year. Rising temperatures increase air conditioning energy consumption across southern states. Louisiana homes often rely on air conditioning for eight to ten months, which increases total electricity consumption.

Improper system sizing raises cooling costs by 15 to 25% by causing short cycling and airflow imbalance. Proper AC sizing improves airflow balance and efficiency, while planning for future AC replacement cost helps control long-term expenses.

Why Air Conditioning Use Keeps Increasing Every Year

Air conditioning demand continues to increase due to higher average temperatures and population growth in warmer regions. The National Oceanic and Atmospheric Administration reports steady increases in summer heat across the southern United States.

Urban development raises indoor heat retention, while modern lifestyles expect stable indoor comfort. New systems improve airflow efficiency through variable speed compressors, reducing energy spikes and stabilizing monthly bills.

How To Reduce Heating And Cooling Costs Year-Round

Homeowners can reduce heating and cooling costs year-round by lowering runtime, improving system efficiency, and reducing heat loss and gain through consistent habits and proper system setup.

Thu, 29 May 2025 09:11:48 GMT

If you have wondered, " What does HVAC stand for?" you are not alone. HVAC is an integrated system for maintaining indoor air quality, comfort, and temperature control in residential and commercial spaces. At Southern HVAC , our certified technicians are here to guide you through everything you need to know about HVAC services with the following article.

What Does HVAC Stand For?

HVAC stands for Heating, Ventilation, and Air Conditioning, a system that regulates temperature, airflow, and air quality. It is implemented in residential as well as commercial environments to regulate the air.

How Often Should You Replace Air Filter? Signs & Schedule Guide

Thu, 29 May 2025 09:06:01 GMT

To keep your HVAC system running efficiently, it is important to change AC filters periodically. Delays can result in a blocked filter and unfiltered air circulation, straining the system. In this guide, Southern HVAC answers the question, “How often should you replace air filters? ” and provides some efficient information to improve system longevity and home comfort.

What Does An Air Filter Do?

An air filter traps dust, pollen, and dirt through the filter media and filter pleats, preventing pollutants from entering your living space. This procedure keeps the air clean and increases the effectiveness of your indoor air quality equipment. Without an air filter, your home is at risk of accumulating pollutants and compromising your HVAC system.

How Often Should You Replace Your Air Filter?

To respond to the question " How often should I change my furnace filter? ", experts recommend replacing your air filter every 30–90 days. Homes with more square footage or pets require frequent replacement to keep the building and home air system clean. Proper filter maintenance is crucial for keeping your HVAC system efficient and your indoor air clean.

Key Factors That Affect Filter Replacement Frequency

Quality Of Indoor Air

Unclean or polluted rooms contain more airborne particles in your indoor air system, reduce the life of the filters, and affect the air quality. Therefore, you need to change AC filters regularly to ensure your family’s health.

Asthma Or Allergies

If anyone in your home has allergies or asthma, consider checking and replacing filters regularly. Our experts advise upgrading to a HEPA or MERV 13 filter to remove irritants from the air sooner.

Pets In The Home

Pet hair and dander fill up HVAC filters quickly, especially without deep pleats on the filter. Dirty filters equate to indoor pollutants, so regular replacement is unavoidable.

Home Size

Bigger homes employ more powerful building air systems to push air through additional space. Therefore, filters inside air-handling equipment clog up faster and need to be monitored more closely. Monitoring usage and scheduling replacements avoids poor ventilation.

Usage Frequency/Seasonality

If your climate control system runs continuously during the summer or winter, your filter has to be replaced more often. In this case, to answer the question "How often to replace air filter?", experts recommend changing your AC filter every 30–60 days during heavy-use months as an ideal answer.

What Happens If You Don’t Replace Your Air Filter?

Reduced HVAC Efficiency : When the filter media becomes blocked, your HVAC system must work harder to force air. This results in reduced performance and makes it use more energy.
Higher Energy Bills : Clogged filters restrict airflow, forcing your AC system to strain. Overloading the system will increase energy consumption if not replaced promptly.
Risk Of System Overheating : Restricted airflow forces your HVAC motor to overheat, making it deteriorate sooner. Changing them ensures safe and efficient operation.
Poor Indoor Air Quality : A dirty filter lets airborne allergens like pollen and dander pass freely. That lowers indoor comfort and can trigger allergic reactions.
Reduced Lifespan : Failing to replace filters in time creates a dirty HVAC system, which can lead to culminating in serious system damage over time. Replacing an old filter extends the system's lifespan and reduces maintenance.

FAQs

What Is A Ductless Air Conditioner?

Fri, 25 Apr 2025 03:15:50 GMT

Want to increase the comfort of your house without having to deal with ductwork? This guide will help you understand what a ductless air conditioner is, how it works, and why more homeowners are turning to these efficient, flexible systems for year-round climate control.

What Is A Ductless Air Conditioner?

A ductless air conditioner, also known as a mini-split air conditioner, has two main parts: an indoor air handler and an outdoor condenser unit. Together, they can heat or cool a space without ducts to blow air throughout the house.

A ductless AC system targets one space directly, not a central HVAC system that blows temperature control from one source to multiple rooms. This air conditioner is wall-mounted and is for those who want a less invasive and more efficient installation.

How Does Ductless AC Work?

A set of refrigerant lines connects an outdoor condenser unit to an indoor air handler in a ductless system. These insulated pipes carry refrigerant back and forth, pulling heat from your room and pushing it outside, or vice versa in heat mode.

The cooled or heated air is blown by a blower fan in the air handler, and the speed is controlled by the inverter compressor according to your room’s needs. A drain line also removes excess moisture, which prevents leaks and mold growth.

Advantages Of Ductless AC Systems

Energy Efficiency: By matching your room’s heating or cooling needs with inverter compressors, ductless systems reduce energy waste and utility bills.
Zoned Comfort: Each room can have its own temperature with zoned systems, and that’s a great way to customize comfort and reduce energy waste.
Quiet Operation : These systems are perfect for home offices, nurseries, and bedrooms where quiet is important because they are designed to be whisper-quiet.
Flexible Installation : Great for small spaces, room additions, or homes without existing ductwork, as they are a small system.
Smart Control Options : You can control many smart ductless HVAC systems from anywhere at any time by connecting to your phone or home assistant.
Improved Air Quality : Ductless systems reduce allergens and move cleaner, fresher air around the house with their built-in filtration and ventilation.

Situations Where A Ductless System May Be Your Best Option

For homes without ductwork or for spaces where extending ducts is impractical, ductless heat and AC systems are a smart option. Here are the typical situations where a ductless system excels:

Older Homes Without Ductwork : Vintage homes can have modern comfort without major modifications by installing a single-zone mini-split system or a multi-zone ductless system.
Homes With Radiators or Baseboard Heating : If your home has baseboard heating or radiant heat, a ductless AC unit can add zoned cooling without affecting the current configuration.
Home Additions or Renovations : Ideal for sunrooms, guest rooms, or expansions to homes where installing new ducting would be expensive or intrusive. Refrigerant lines need minimal space and may be mounted quickly.
Garages, Attics, and Basements : Vents are often missing from garages, attics, and basements—those tough spaces. They are livable year-round with a wall unit or mini-split on the floor.
Vacation Homes and Cabins : Ductless systems are ideal for seasonal or part-time settings, providing comfort only where and when needed.

Ductless Mini-Splits Vs Ducted System

The fundamental function of both ductless mini-splits and conventional central HVAC systems is to heat and cool your house, but they approach this task rather differently.

Pricing

While a ductless system may cost more upfront, it will pay for itself. Homeowners see a big drop in their monthly bills due to zoned HVAC and reduced energy loss, especially when replacing a central air conditioner that uses a lot of power.

Noise Levels

The whisper-quiet AC of ductless units is one of their best features. Ductless systems are designed to produce very little noise, perfect for areas where quiet is important, like bedrooms, nurseries, and home offices, versus central systems or older window units that hum and rattle.

Installation Complexity

Ductless system installation is quick and non-invasive. Just a small hole for the refrigerant lines is required; no ductwork or extensive modifications are needed. Compared to ducted systems, it’s simpler and less labor-intensive.

Space Requirements

Whether you have limited wall or ceiling space, there are multiple mounting options like wall-mounted, floor-mounted, or ceiling cassette units that blend in with your space without taking over.

Energy Efficiency & Savings

Ductless systems are known for their energy efficiency, especially with high SEER ratings and inverter compressors. Perfect for homeowners who care about the environment and want to lower their long-term costs because they use less power, have precise temperature control, and minimize energy waste.

The 8 Benefits Of AC Repair Service

Fri, 25 Apr 2025 03:03:28 GMT

Especially in the warmer months, having a reliable air conditioning system is key to both comfort and energy savings. Knowing the benefits of AC repair helps homeowners see how timely fixes can improve performance, extend system life, and improve indoor air quality. Regular AC services are the smart and cost-effective way to keep your home in working order, whether you’re fixing small issues or preventing bigger ones.

1. Extend The AC Lifespan

Your AC will run more efficiently and last longer with prompt repairs and maintenance services. In Hammond, where summer highs often climb into the 90s with sticky Gulf Coast humidity, AC units work extra hard. Regular repairs help prevent premature wear in this demanding climate, keeping your system reliable season after season. Easy fixes like clearing the drain line, cleaning coils, and changing filters will ease system stress and prevent costly breakdowns.

2. Purify Air Quality

Your air conditioner filters the air you breathe and also controls the temperature. Dander, pollen, and dust can accumulate within your system over time. If the filter isn’t changed often or ducts remain dusty, indoor air becomes stale and irritating.

For allergy sufferers in particular, replacing high-efficiency filters and clearing out airflow paths has a considerable effect. When everything is working right, your house smells better, and your system needs less effort to blow cool air.

3. Reduces Humidity Indoors

South Louisiana’s subtropical weather means humidity levels can remain high even indoors. Unchecked humidity negates cooling efforts, making spaces uncomfortable and mold growth a danger. A well-maintained air conditioner not only cools the air but also removes excess moisture. Condensate line cleaning and moisture control checks are easy tasks that bring big comfort. This not only improves the atmosphere in your room but also prevents mold and mildew, which thrive in damp environments.

4. Add-on System Upgrades

The best time to think about minor upgrades is during AC repair. You can start saving energy now by installing a smart thermostat or changing your settings. More than just keeping you cool, modern air conditioners can learn your habits, make adjustments on their own, and even notify you when they need AC maintenance.

5. Increase HVAC System Efficiency

Efficiency is key to low energy bills and high comfort. The system works harder when airflow is impeded by old components, leaky ducts, or unclean coils. This puts stress on the engine, reduces the life of your air conditioner, and increases monthly bills.

Your air conditioner runs best with regular cleaning and adjustments like sealing duct leaks or replacing worn-out parts. And when your HVAC unit matches your house size and needs, it will perform consistently with minimal waste.

6. Improve Health & Comfort

A healthy lifestyle includes sleeping in a comfortable place and breathing clean air. Poor air circulation from an unmaintained air conditioner can exacerbate allergies, disrupt sleep, and cause uneven cooling in your house.

Your everyday comfort is increased by changing filters, adjusting airflow, and making sure the system controls humidity and temperature. These are more important for households with pets or respiratory issues.

7. Clear Out Unwanted Pests

Bugs and other small animals can also infiltrate poorly maintained systems, in addition to dust. Unwanted visitors can enter through leaky seals or clogged drainpipes. Additionally, standing water within the system encourages the growth of mildew and draws bugs.

In addition to keeping your air conditioner operating more efficiently, fixing leaks, removing debris, and caulking gaps helps shield your whole house from long-term damage and pests.

8. Save Money On Energy Bills

Energy costs can spike quickly during Hammond’s long cooling season, when AC systems often run around the clock. Utility bills will rise rapidly if a unit operates inefficiently, cycles too frequently, or blows hot air. By replacing filters, improving ventilation, and updating thermostats, you can reduce the load on your system. A tuned system not only saves money but also keeps your home comfortable despite Louisiana’s relentless summer heat.

When To Replace Heating And Air Conditioning?

Wed, 26 Feb 2025 07:47:01 GMT

Using HVAC systems helps keep your home comfortable, but many people are still unclear about the replacement of HVAC systems. With the question of many customers about "when to replace heating and air conditioning?" Southern HVAC helps you understand the use, maintenance, and replacement of HVAC systems.
