"Great job doing maintenance service on the furnace and heat pump. Received informative answers to my questions. Very professional interaction. Been doing business with AirPros Energy for over 10 years servicing my furnace, heat pump, gas fireplace, tankless water system and have always been satisfied."

"Took about 2.5 days to remove an antiquated panel, meter and mast and replace with a more modern one. They also cleaned up a bunch of wiring issues in the house and ran conduit and power for an HVAC system. I am still pending power company inspection, but I'm sure the work will pass easily."

"This was an excellent customer service experience. I selected Day & Nite Plumbing & Heating in Lynnwood, WA on the strength of Angie's List reviews that describe actual furnace repair work rather than other companies that seem more focused on doing furnace replacements. (Day & Nite do replacements, of course, but the reviews cited a fair number of repairs as well.) Although my gas furnace (a Carrier Weathermaster 800) is about 20 years old, my circumstances didn't allow replacement. When I contacted Shondra in their office about available appointments they were booking several days out, but were able to move it up a day and a half which was very appreciated given the cold nights. Tyler was the HVAC-R Technician sent for my appointment and he was amazing - both personable and knowledgeable, he listened to my concerns and quickly diagnosed and fixed the unit. He also understood that I am someone who likes to know details on what is being done and why – not too much detail, but enough so I felt informed which reassured me. Tyler’s great customer service and positive attitude, on top of his knowledge and experience with the technology impressed me so much I signed up with Day & Nite for their annual furnace maintenance plan next winter and will happily refer my friends and family for their furnace needs. I have yet to experience the Day & Nite plumbing services, but on the strength of my experience with Day and Nite and support by Tyler, I will give them a call when that need arises. (FYI: The approximate service cost of $600 included the ignitor part less a 10% customer discount for signing up for the maintenance plan, the trip charge and that for next winter’s maintenance trip, plus tax.)"

"Recently we had to have our AC unit repaired. We asked several providers to come and give us quote. We settled on Cascadia and glad we did. The repair individual was prompt and professional. He showed up when promised and completed the work in a timely manner. The final bill came in as quoted and was reasonable for the work required. Would confidently recommend Cascadia. 5 stars."

"I had an appointment to get my ancient gas furnace tuned up and I have to say, the technician Kevin did an excellent job. I I could give him more than 5 stars I would. It started with how nice and polite he was. He put a mask on when I asked without giving me a hard time. This is very appreciated. Then he noticed something was not hooked up (the fan only function) and he fixed it. Then he noticed the holder for my filter wasn't seated right so he fixed that (which was no small amount of work), and then he cleaned two areas of the furnace I NEVER saw anyone else clean in the 15 years I have lived here. Then he cleaned everything up and made sure to explain everything well and made sure I was happy with everything. I cant even believe the excellent service. On top of that he was quick, efficient but did not make me feel rushed. This ancient furnace is working better than it has in years! Do not hesitate to go with Smart Electric - they are top notch - oh yeah - on top of all of this great service, the price was $100 less than other companies I had out to do the same job! The other companies charged more and did less. Smart Electric just got a customer for life. I highly recommend!!!"

"I initially hired this company to do a routine maintenance on my heating/cooling equipment. In the middle I needed to have the blower on the forced air system cleaned and rebuilt. The blower failed shortly thereafter and Air Ductors replaced the blower at cost. The next blower was bad out of the box! They came back promptly and were able to help us keep an elderly mom/in-law who lives with us and is heat vulnerable comfortable in extreme heat conditions! Air Ductors encountered problems and overcame them with a great attitude."

Heating and Air Conditioning FAQs, answered by experts

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.
