"They installed central heating and air in our home in 2025. They were efficient, did a excellent clean up, and friendly. They checked in a week after to make sure we were satisfied with the system and if we had any questions. We are extremely satisfied with the new system. The controls are easy to work and the system is very quiet and efficient."

"We have been using Golden Aire for maintenance and repairs for the past 8 years. They are professional, knowledgeable and courteous, as well as fair in their pricing. Case in point, we had Daniel come out to do our summer A/C maintenance. Daniel discovered that coils were bad and leaking coolant. We received our quote for the parts and repair. The cost was estimated at $3k (ouch!) Parts were ordered and Daniel came out within a weeks' time. I can't state highly enough how impressed we were with Daniel's knowledge, professionalism and most importantly care. Daniel was able to save us $1,300 as he discovered that after fixing the Nitrogen leak and replacing the refrigerant there was no need to replace the coils. I know other less scrupulous companies would have milked us for a higher invoice price especially since the coils were ordered. Thank you, Daniel, and Golden Aire for your honesty and professionalism."

"My HVAC air system stopped the night before Father's Day. I could not find anyone to help me until the following Wednesday. Kazen was the only one who would come sooner. He was at my house only ten minutes and had the air working"

"I met Jesse (owner) at the Auburn home. After setting an appt., he showed up on time as promised (can t say that for a lot of other companies). We reviewed what I wanted done which I appreciated because I ve had others suggest what they wanted done instead. He physically went up into my attic to access my old and inefficient insulation, including video recording it. He also spent time looking at my old windows (1980 s style) that I was also looking to replace. Jesse came up with the cost which was thousands of dollars cheaper then the several other estimates I have received. After agreeing on moving forward, Jesse played an active part in the entire project. He even provided me with his cellular number and always got back to me when any questions arose. The workers who came to install the insulation were very friendly and professional (I continuously talked to them, probably annoyingly). They took their time to assure that everything was done as promised and I even double checked their work. The next part of the project included a new slider and several windows. Jesse was on scene throughout the window installation and the final product was fabulous. Craftsmanship was impeccable and the windows and slider look great. Even after the project was complete, Jesse has contacted me to assure full satisfaction was met. I would recommend Clear Efficiency to anyone."

Heating and Air Conditioning FAQs, answered by experts

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
