"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."

"Ben Fish showed up right on time, went up to my attic space for a visual inspection (something I should have done a long time ago but didn't) and measured the depth of insulation, appliance efficiency, energy loss from floor/walls/windows, and put it on a nice, easy-to-read spreadsheet, as well as throroughly explained everything.  There was absolutely no pressure to buy anything, as there had been in the past with HVAC repairmen.  One reason I wanted this audit was for the impartial 3rd party feedback, which is exactly what I got.

"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."

"WOWWW! Above & beyond service, courteous & knowledgeable technician, and fair pricing... what more could you want?! I contacted Air Control Systems via Angie's List and (literally) within minutes received a phone call. They were able to send a technician out that same day (rare in todays service industry!) at no extra charge. Nathan was very personable yet prompt. He fixed the issue, while also checking everything else out to ensure peak performance moving forward. The cost was very fair, and I will not be using ANY other company for HVAC issues in the future! Outstanding!"

Heating and Air Conditioning FAQs, answered by experts

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees.
