"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."

"Chris was extremely professional and very skilled at his trade. He completed the work within 2 days of our first contact and kept excellent communication about costs, time of arrival for first consultation and date of service. The projects were challenging and he did incredible carpentry. He was very good at keeping the area clean and respectful of my home. We have already discussed additional work that he will do on the house. I am excited to work with him again and recommend him without reservation. He is a breath of fresh air for someone to really work with a homeowner!"

Air Conditioning FAQs, answered by experts

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.
