"Our 14 year old HVAC system was starting to have problems, mainly with the A/C system which had a persistent coolant leak. With the increasing cost of R22 Freon we knew the time was near and a spring replacement was planned. That was before the blower motor in the furnace started to make a terrible noise and quickly failed, moving up our timeline. We had already done our research and decided on a Trane system. Based on overwhelming positive reviews and a co-worker referral, we decided to call Westin Air for an evaluation and quote. Our experience with Cathy, Westin's sales rep, was very pleasant - a full assessment of our needs and review of our options and no hard sell. The system suggested was the Trane S9V2 furnace with the XL18i air conditioner. Since our A/C was not working, installation was scheduled within a few days. The installation crew was incredible. They put tarps down on the hardwood floor and went above and beyond when it came to being careful. They cleaned up inside and out to the point you would never have known they were at the house. Our experience with Westin Air mirrored all of the positive reviews we read online. The office staff, salesperson and install team were all enjoyable to work with. There was a sense of honesty and integrity in everyone we encountered. There would be no hesitation to recommend Westin Air."

"Carl, the technician, came quickly and was thorough and professional in his work. He diagnosed the issue with our air conditioning and provided several payment options to see what worked best for us. He had to order parts for our air conditioning so he even offered to find window units for us to keep our house cool in the heat until it can be fixed!"

"Joe, Tyler and Kevin are awesome. They did an Execellent job in installing the Aprilair 700 whole house Direct feed humidifier. Joe kept me in the loop the entire time. Besides the electrical work, Tyler also helped set up the Nest thermostat- as I am very new to this. Thanks for the mini training session as I can control the humidity only thru the mobile app. There was a minor hiccup after they left. I called the office, and they returned within an hour and took care of it. Very happy with them. BTW, they all wore masked the entire time, which, I appreciated. Thank you."

Air Conditioning questions, answered by experts

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

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 reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.
