*Update: Company called to offer an explanation as to why they don't offer service in attic. Appreciate that effort. Discussed possible solutions and places that can give the service we need, and possibly having them update a website to help clear communication in services provided & not provided. -Came home from vacation to HVAC system that kept blowing a fuse and the air conditioner would not run. Called at 5:30pm for an appointment the next day. Informed them that HVAC in the attic was blowing a fuse and was told we'd get a call the next day.

When we didn't get a call the next day we called and were informed that they don't do attic work because it's dangerous to it's employees, a policy across the board. Certainly weather should always be considered to the health of the employees but I'm pretty sure a company could schedule around this, right? There are plenty homes in the PNW that have furnace and HVAC systems in the attic, and if your one of them skip to next provider.

This is my second time working with Overlake Heating and AC, and it was as good as my first experience. I got an appointment within three days to get the thermostat fixed in a rental property. Clear and reasonable fee schedule which they were upfront about at the time of making the appointment. Called me 30 minutes prior to reaching the home, and were courteous and polite during their appointment. Finished the replacement quickly and didn't try to upsell anything. They're my go-to guys for anything heating/AC related!

Deciding which equipment to replace can be a hard decision for new home owner like me but Robert made it fairly easy. He patiently explained to me the differences and also provided suggestions. I've had them replaced my water heater, furnace and also installed a new air conditioner. After the installation the infrared sensor was moved by accident and my garage door wouldn't shut. Robert responded in no time and sent the technician back and fixed it. Their schedule were quite booked up and I would suggest spare enough time planning ahead. I would definitely recommend this company for its competitive price and great service.

Got a code 14 on the furnace we bought from Overlake 4 years ago. Called them at 8, they came out at 12:45, fixed and running by 1:30, part was under warranty as well. FIVE ***** STARS all day long! Service: Heating system repair

My furnace stop working two weeks ago. After terrible experiences with another company, furnace still stay dead. My neighbor referred me to Overlake Heating and Air Conditioning, 2 service tech came today and fixed my furnace immediately on the spot. Highly professional, honest, very helpful. Overlake Heating is the best since I moved to here 10 years ago. Thanks for great job.

Was disappointed that I received no return call after speaking with someone at their after hours number. My name and number were taken and then nothing happened. Why list a name and number for after hours service if you have no intention of helping? Update: Robert called next day after my review and indicated that they had tried to call back. I had no record. After some exploration, it was determined that the tech had left a message on another number after transposing a couple of numbers. Clearly Robert cares very much about his business and customers. I appreciate his follow up.

When our furnace broke down we called several HVAC companies for estimates. My experience with Rob was the best of all. The articles on their website are the best. Rob clearly answered all our questions and gave a fair estimate over the phone after I sent him some picture. (Other companies did in-person estimates.) The crew that came for the install did a great job.
