If your HVAC system is more than 20 years old or in need of major repair work, it’s time to consider replacing it with a more energy-efficient model. However, don’t make a rushed decision; take the time to do your research first. Before you commit to a new system for your Dallas, Texas, home, figure out what type would work best, what size HVAC unit you need, what kind of maintenance it requires, and if you should make any home energy improvements first.

What Type of System Do I Need?

The kind of HVAC system you need depends on your home’s layout as well as your comfort requirements. HVAC units with higher Seasonal Energy Efficiency Values (SEER) are more expensive to buy but they cost less to operate. When you look at the cost-savings over the life of the unit, it might make sense for you to spend more upfront on one with a higher SEER value. However, if you’re only planning to stay in the home for a few more years, a high SEER value might not be as important to you.

You might want to consider installing a zoned system, which will enable you to enjoy varying comfort levels around your home. A zoned system is a good option for two-story homes, but these types of systems are often more attractive for new builds than existing homes. One of our experienced technicians can give you more information and advice if you’re interested in this option.

What Size HVAC System Do I Need?

Installing a correctly sized HVAC unit is probably the most important step in the HVAC replacement process. Units that are too big or too small can cause all sorts of issues that drive up your utility bills, lead to expensive breakdowns, and ultimately decrease the life span of the unit.

An HVAC technician will perform a load calculation test to determine the size unit you need. This test takes several factors into consideration. While your home’s square footage is the most important determining factor, other considerations, such as your home’s layout and the climate of your area, are significant, as well.

How Do I Maintain My New System?

Regular maintenance is vital to the health and longevity of your new HVAC unit. While you should have a licensed HVAC technician complete most technical tasks, such as inspecting the indoor and outdoor units, there are several simple tasks you can do yourself. For instance, ask how often you should change the unit’s air filter. While most filters require replacement every three months, make sure this is the case for your new unit, as some require replacing more frequently.

Also keep the area around the outdoor unit clear of debris, and consider installing a smart thermostat to make the most of your new unit’s energy efficiency. Ask the technician for any tips that will help your new unit operate more efficiently — this advice can save you money on utility and repair bills.

Should I Make Home Energy Improvements First?

When replacing your HVAC system, it’s wise to conduct an energy audit first. A professional energy auditor will inspect your home using special techniques and tools, such as a blower door test — a test that utilizes a blower door machine to depressurize your home and an infrared camera to identify any air leaks. After determining where energy loss is occurring, the auditor will suggest upgrades you can make to prevent it. You’ll receive a report detailing ways you can improve the overall efficiency of your home, which can maximize the energy savings you’ll experience with a new HVAC unit.

If you don’t have time to wait on a professional audit, you can conduct a mini-audit of your own. Examine doors and windows for air leaks, check your insulation, and switch out your lighting for more energy-efficient options.
