We strive to ensure each and every customer is 100% satisfied with our work. Give us a call today to see how we can create a “Taylor-Fit” solution for your home!

"Tyler from Taylor heating and AC was the best. It was a hot Saturday (mid 90 degrees) and he crawled up into a 115 degree F attic to help resolve our AC. Not only did he identify the problem, he also fixed the issue for us on the spot so we could have AC during this heatwave—all while working under immensely hot conditions. I’d give a 10 out of 5 stars if I could."

Our team of experienced HVAC Seattle workers can handle any job, no matter how big or small. Need a new gas furnace to meet your Seattle heating needs? We’ve got you covered. Looking for Bellevue air conditioning? Not a problem. It doesn’t matter if you live in a small apartment that needs a new HEPA filter or a large business with a long list of Seattle or Bellevue heating and air conditioning needs. Just give us a call, and we’ll be happy to help.

"I won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

"We went with Greenwood because we heard that they would take care of us, even though they were more expensive. We had a great experience with the first walkthrough with a knowledgable expert, but every interaction since has been poor. We had several issues with the installation; they had to come back several times. Five years later, the water pump with the furnace broke and they take care of it, but it costs $900. They take care of us, but continue to be expensive. I highly recommend avoiding this company and finding a business that knows what their doing and where all technicians care about the customer."

Boiler Repair questions, answered by experts

Over time, a radiator can leak if turned off due to the built-up air pressure, which can cause water or coolant to leak. If your radiator leaks when it’s off, turn your whole system off and bleed the radiator, then turn it back on. If it’s still leaking, you might want to have an HVAC professional look at the issue.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

You’ll want to bleed your radiators at least once per year, typically in the fall before you plan to turn on the heat. Bleeding a radiator is a regular part of your heating system maintenance, and you’ll need to do this regularly to keep these units running efficiently. You should also bleed radiators any time they start making noise, like gurgling, hissing, or banging.
