"Integrity Air is A-1 in my book. Great prices, great installers and wonderful customer service. I had been told by other HVAC companies that AC would not fit in the space I had, but Integrity found a way and did a wonderful job. The installers were quick and very courteous, my salesman answered every question I had. And the price was very reasonable, much lower than I expected."

"This is actually my second time using Better Air Northwest. We used them last year on the home we were selling and I was impressed with them at that time so I had them come to our new home this year. The arrive on time, are very professional and explain everything as they go along. They discovered a section of the duct work that was damaged so we had them come out a second time and replace that section. We received the same quality workmanship."

"Beyond excellent. Found out our shops HVAC was out, mind you it’s already 2 pm and pushing 90 degrees outside. Contacted Revival Energy and within an hour, a repair man was addressing the issue. He was able to fix the problem with the upmost kindness and professionalism, all while maintaining social distancing. Definitely saved the day for the shop. 11/10 would recommend."

"They did a great job in a timely manner for a good price. I would recommend them. They came out and attempted to fix my furnace. The initial fix solved one problem, but then an even larger problem was found. At that point they recommended replacing the furnace as it was already on its last leg anyway. I got a quote for work from them and 2 other companies. The other companies agreed a replacement was the best option. Integrity Air had the best price. Their technicians were very friendly and explained what they were doing during all steps. They were prompt with their service. I had a secondary source for heat (gas fireplace inside), so I was in no rush and had the service calls when it was convenient for my schedule. They did have appointments available sooner had I wanted and needed the heat fixed sooner."

"Very pleasant experience. Punctual and professional. It would have been helpful to know the amount of noise that putting in a new furnace causes, I would have rescheduled some of my business activities, but the job was done well. Duct work was brought up to code and passed inspection. However at my home, there was an issue passing the inspection. They did not vent the air conditioner adequately. When we failed the inspection, they came out on that very day and corrected the problem. There was/is the inconvenience of a second inspection."

"I accepted bids from several different vent cleaning services, including two suppliers outside of Home Advisor network. PowerVac, LLC was not the lowest bidder, but I went with them because of their willingness to explain their process in detail over the phone. Mary spent quite a bit of time answering my questions over the phone was able to offer me several available time slots in the near future. The service crew showed up on time and did a very good job. They were especially careful to clean up and not leave a mess. They worked well together and were very fast and efficient. I highly recommend using PowerVac LLC for your vent cleaning needs."

Heating and Air Conditioning FAQs, answered by experts

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
