"I went with this company to replace my furnace and air-conditioner. My furnace went out on a Friday night, they came out to give me a bid on Monday and replaced both units on Tuesday. I chose them because their price was within $100-$200 of the big companies, but Precision is owner operated. The owner gave me the bid and was here to do the installation. I appreciate the owner doing the installation as he has a lot of experience and will be the one I call if something goes wrong. They only took 6 hours to do both installations - it was quick, clean, easy and well done. Highly recommend."

"Jarad came to inspect my air conditioner. When the furnace and air conditioner was installed, they took time to explain how they worked and what I needed to do from one season to the next. However, there was so much information exchanged then, I forgot part of it. Jarad took the time to thoroughly explain everything. He also looked at another concern of mine, and he fixed that. I couldn't have been more pleased."

Air Conditioning questions, answered by experts

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

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

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.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.
