Top Factors to Consider When Replacing Your HVAC System

Old air-conditioner School’s out and the fun days of summer are here! For Atlanta homeowners that means it’s time to turn on the air-conditioning. This is also the time of year when people think about replacing their HVAC system. If this is the year you’re considering a new system, here are a few things you’ll want to keep in mind.

Do I Really Need a Replacement?

The final answer to this question should come from a qualified contractor who specializes in HVAC replacement in Atlanta. However, there are some general rules that can help you determine whether you should repair or replace your system. First, if you own an aging HVAC system, you may want to update to a modern, more efficient unit. An older system may end up costing more to repair than to replace. For example, what type of refrigerant does your system use? If it’s R-22, keep in mind that it’s on its way out. Today, systems use a more efficient and environmentally friendly refrigerant. An out-of-date refrigerant along with obsolete parts could result in higher long-term maintenance costs. Other factors that determine whether a replacement in your future include how often you use your system and the area of the country where you live.

Unique HVAC Needs in My Area of the Country

The muggy, humid summers common in the Southeast require unique methods for selecting HVAC equipment. In Atlanta, high daytime heat is common. Humidity is also an issue both during the day and at night. High heat and humidity can tax your HVAC system. Talk with your contractor about the correct size for your home and climate. Also, ask about two-stage systems. Why does correct size matter? If you install a single-stage unit and it’s too large, it won’t properly dehumidify. A unit that’s too small will dehumidify but won’t cool the home efficiently. Two-stage systems help avoid this issue. They let the system run at a lower capacity. This means the system can run longer while pulling more humidity out of the air. A two-stage system can also work at full capacity on those extremely hot summer days.

How Large Is Your Space?

AC installationMost homeowners assume they can replace their HVAC system with one that’s the same size as the old unit. That’s usually true but there are a few scenarios where the same size won’t work. For example, if you’ve done any remodeling and added doors and/or windows, you’ve likely changed the area you need to be cooled. Adding an addition also changes your cooling needs. Sometimes homeowners think bigger is better and that’s not always the case. If the system is too large for your space, you’ll end up with higher cooling and heating bills. Discuss any changes you’ve made with a professional who offers residential HVAC services in Atlanta. They should perform a load analysis of your home. This helps your contractor properly size the unit for your unique needs.

These are only a few factors you should look at when considering the replacement of your HVAC system. Other things you’ll want to ask about are promotions and possible energy rebates. For answers to these and other HVAC questions, call Cool Air Mechanical at 770-266-5247 today.
