What folks are saying about Overlake

Choosing a heating and cooling contractor for your home can be a difficult decision. We don’t expect you to just take our word, so we encourage you to take a look at our awards page to see the many customer service awards we’ve won over the years.

Air Conditioners

We admit, here in the Pacific Northwest, many do not regard an air conditioner as a priority. But each year, when Summer eventually arrives, the days often do become uncomfortably warm, and it’s nice to have a cool, dehumidified safe haven. In fact, a couple of Summers ago (2015) we averaged the hottest temperatures on record for the Northwest, dating back to 1895.

We provide a full range of central air conditioning products and services. Whether your A/C is due for annual maintenance, requires repairs, needs to be replaced, or you’re just sick and tired of being too hot during the Summer and would like a new unit installed—we’re here to help. Give us a call, and we’d be happy to discuss our products and services and schedule an appointment.


Heat Pumps

Central heat pumps are able to both heat and cool your home. When a heat pump is cooling, it operates identically to an air conditioner. And while a heat pump won’t replace your gas or electric furnace, installing one can give you the same cooling as an air conditioner while potentially saving you money on heating your home. If you’re not sure whether your home could benefit from a heat pump, give us a call and we can walk you through everything.

Overlake Heating & Air Conditioning provides a full range of central heat pump services. From routine, annual maintenance and repairs to entire installation and home replacement jobs, our technicians are highly-skilled, meticulous, and prepared to tackle any central heat pump service.


Furnaces are the go-to heating appliance here in the Pacific Northwest heating over 98% of homes. We provide a full range of furnace services for all brands and models of gas, propane, and electric furnaces. Whether your furnace is due for scheduled, annual maintenance, has an issue or is malfunctioning, or just needs to be replaced we’re happy to help.

If you’re looking to replace your furnace, give us a call-we’ll survey your project, educate you in the different options, and provide you with a free estimate.


Water Heaters

Overlake Heating & Air Conditioning knows water heaters, too, and can perform routine maintenance, fix any issues, and even replace your current system.

If you’re in the market for a new water heater, we’d be happy to take the time to listen to your concerns, educate you about your standard models versus tankless, survey your project, and provide you with an estimate—all free of charge.

We offer Bradford White and Ruud/Rheem gas and electric water heaters as well as Navien and Rinnai tankless systems.

Thermostats and Controls

The thermostat is your interface with your heating and cooling system instructing it when to operate. It can be as simple as manual temperature control or as dynamic as an automated system capable of precisely meeting your indoor climate specifications. If you’re interested in purchasing a new thermostat, or are having issues with your current unit, or would like to look into other indoor climate control options such as humidity control, we can help.

Some of the more popular thermostats on the market are Nest, Ecobee, and several different Honeywell thermostats. The manufacturer of your heating or cooling equipment likely offers their own thermostats, which in certain scenarios can be the preferred option.

Duct Cleaning

Let us help you improve your home’s air quality. Did you know it’s recommended to clean your air ducts every three to five years. Why? Over the years, pollen, animal dander, dust and dirt accumulates in the air ducts of your home. Each time you flip on your heating or cooling system, air kicks up the particulate and either you breathe it in or it lands on your furniture and carpet. A cleaning nuisance, yes, and often a health issue. Allergies and asthma can be severely aggravated by these airborne pollutants constantly swirling around your home.

Beyond routine maintenance, we recommend you have your air ducts cleaned if there is a substantial amount of visible dust on your grilles and in your ducts.

Routine Inspection and Maintenance Costs

According to manufacturer’s, furnaces, heat pumps, central air conditioners, and tankless water heaters all require regularly scheduled inspection and maintenance. Generally they recommend this should be performed annually to sustain safe, peak performance and to minimize system malfunctions.

A full-service tune up for a furnace, heat pump, central A/C, is currently $15 off the regular price of $150.00, plus tax. Each additional unit is $115.00 each, plus tax. For tankless water heaters, annual maintenance is discounted $25 off the regular price of $225, plus tax.
