"This was 100% worth hiring this company! I recently purchased a home that previously had a heavy in home nicotine smoker. I wanted the start fresh and clean the ducts and they made hiring and completing the service so worth it. They were extremely responsive and very reasonable in pricing. I would recommend them to anyone needing duct work cleaning."

"Very good. This was our first time having this done so we didn't know what questions to ask to get a complete estimate. Because of this they added extra services to ensure we would be happy with their work. Very polite and clean. Would definitely hire them again."

"Dillon and George were efficient, friendly, fast, fun, and really know what they're doing. Dillon explained the work details, answered our questions, and was upfront with costs, which we felt were reasonable. It was amazing what they cleaned out of our duct work (even an old dead mouse...ick!). We plan to use Preferred Home Improvements again in the future...thanks guys!"

Heating and Air Conditioning questions, answered by experts

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.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

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.
