"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

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.
