"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."

"We were very pleased with the service that we received from CARE! I contacted three different companies and they were the first to respond and their estimate was the cheapest. We were looking for a basic system and that is exactly what we got. We did not feel pressured to get anything more than we asked for and Andy was very helpful. Matt and Kirk, who installed our new system, were fast and efficient. We will definitely contact CARE again in the future for any HVAC needs."

"Tyler replaced our 22 year old central air conditioner. From the initial call for a quote to the final installation the entire project was perfect. His years of experience were obvious as the job was professionally handled. He later serviced our gas furnace, explaining all of what was occurring while giving the furnace its best check ever. Delta-T is our "go-to" HVAC firm in the future."

Heating and Air Conditioning FAQs, answered by experts

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.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.
