"Worked with Tim - was looking for new HVAC system. He was honest and provided the best price for what you got (literally thousands of dollars cheaper from other options I was finding). Was very communicative and easy to work with. He made sure to educate you on the ins-and-outs of HVAC systems, and did not try to upsell you like other companies might do. He and Efficiency Air definitely got me as a new continued client."

"It was installed with a kink in the condensation hose and was not aware that it leaked under our hallway wood floor. This was June 2022. I paid to have a leak detection company come out and say the floor was OK. In August 2022, we ran HVAC for a couple of days during the heat wave and water came out of the HVAC unit, ruining our hallway wood floor. It is 10/29/2022 and we still have not heard from their office on how they are going to fix our floor."

"I had estimates from four HVAC companies. Hilo Aire speaks VOLUMES without any regrets. Everything from A to Z went beyond my expectations. The crews were so good that they took their time to inspect and install the cooling and heating systems. I’m truly IMPRESSED. Ask for Chad and/or Brett. KUDOS to them and the crews."

Heating and Air Conditioning questions, answered by experts

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.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.
