"We noticed a foul smell coming from one of the vents in our HVAC system. We turned the system off and called AC Dave. Dave sent Justin and James to troubleshoot the problem. They quickly found a tear in one of our ducts--and the remains of a dead rodent. They cut open the duct, cleaned it and resealed it. We had heat again, about an hour after they arrived. Very fast and competent service."

"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"This company is the best! They installed a new HVAC system a little over a year ago and it was a terrific experience. They had a great price, were prompt, clean, polite and the system works perfectly. They came for a routine service and replaced a filter. Prompt, polite, and no pressure to upsell. Just very honest, fair price and great in every way."

"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!"

Heating and Air Conditioning questions, answered by experts

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on
