"We've lived in our house for many years, but the air ducts and vents haven't been cleaned in some time. We had Bactronix clean, disinfect, deodorize, and protect our HVAC system, and we we were thrilled with the results. Bob and Frank were thorough, efficient, and professional throughout the process. We'd certainly recommend their services to others."

Heating and Air Conditioning FAQs, answered by experts

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.
