"Awesome job!!! I called several HVAC companies before contacting Cody. Cody explained all the technical aspects of my issue and even defined the technical terms I didn’t know on the initial call. Not only did he help me understand my problem more clearer and help guide me down the various routes I could take to remedy them, he quoted me almost 50% lower than most companies. After agreeing to the service, he was able to perform the service the following day to restore my AC. Upon arrival with his crew, I asked him how long did he think it would take. He said an hour. It took 1 hour for him to install my new AC. After a week of guys trying to rip me off, Cody and his crew reconfirmed my faith in honest service. I absolutely would use them again and would refer them to anyone needing any kind of service. Excellent service. Very professional. More than anything, HONEST!!! A++ if I could rate it. They should be the ones you call if you need HVAC work!!!"

Heating and Air Conditioning questions, answered by experts

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Yes, high-efficiency models reduce environmental impact with lower energy use.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
