"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

"Trinity HVAC got in touch with me right away and their communication was excellent, letting me know when someone could come out and they showed up as scheduled. Chris inspected the unit inside and outside to assess the situation then thoroughly explained the problem before doing the work. He provided a follow-up email with the invoice showing the detailed items that were repaired and photos."

"David Parks Senior HVAC Technician was very knowledgeable and listened to my needs. Susie in the office was polite and a joy to speak to. The crew that installed the ductwork worked efficiently and cleaned up afterwards. SoCal Climate Control did everything they promised at a reasonable price. I would recommend them to my neighbors and family members."

"Mario and his crew did an amazing job for my family. His prices are amazing with today times. Most companies want to charge over $20k for the same system I got with him. It's also the same warranty. The craftsmanship is amazing and the attention to detail is there. I would recommend him to any friends or family. I have the peace of mind that I picked the right contractor and company. I will hire him for my next hvac project."

Heating and Air Conditioning FAQs, answered by experts

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

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.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.
