"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."

"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 FAQs, answered by experts

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.
