What Does a Heating Contractor Do?
A heating contractor is a licensed professional who installs, repairs, and maintains the systems that keep your home warm and, in most cases, cool, too. That includes furnaces, heat pumps, boilers, ductless systems, air handlers, thermostats, and the ductwork that connects them.
A good contractor also sizes new equipment correctly, handles permits, and stands behind the work with a warranty.

Is Your Sammamish Home's HVAC System Original?
Much of Sammamish and the Issaquah Highlands was built in the 1990s and 2000s. If your home still has its original furnace or air conditioner, that equipment may be 20 to 30 years old, well past the typical lifespan.
Older systems tend to lose efficiency, need more frequent repairs, and use outdated refrigerants that are expensive to service. Replacing them now, on your own schedule, is far less stressful than an emergency replacement on a cold January night.
Built for Plateau and Foothill Winters
Homes on the Sammamish Plateau and in Issaquah's foothill neighborhoods often see colder nights and more snow than homes closer to Lake Washington. We take that into account when we size equipment. For many homes, a cold-climate heat pump or a dual-fuel system that pairs a heat pump with a gas furnace offers the best balance of efficiency and dependable heat.
Ductless Heat Pumps for Eastside Homes
Ductless mini-splits are a smart fit for bonus rooms over the garage, finished basements, and older Issaquah homes without ductwork. Each indoor unit has its own controls, so you can heat or cool individual rooms without running the whole system.
Our Service Process
- Schedule: Book by phone or online at a time that works for you.
- Diagnose: A technician inspects your system and explains what's wrong in plain language.
- Choose: You receive clear, written options with upfront pricing before any work begins.
- Complete: We finish the job, test the system, and clean up before we leave.

Frequently Asked Questions About Heating Contractors in Issaquah & Sammamish
How much does it cost to install a heat pump in a 2,000-square-foot house?
Cost depends on whether your home has existing ductwork, the efficiency rating you choose, and whether you're adding backup heat or a multi-zone ductless setup. Insulation, window quality, and your home's layout also affect the size you need. We provide a free, itemized estimate after a load calculation.
Which company is best for installing a heat pump in the Seattle area?
Choose an installer who performs a proper load calculation, offers multiple equipment options, and backs the installation with a labor warranty. Greenwood has installed heat pumps across King and Snohomish counties, including Issaquah and Sammamish, and has earned more than 1,000 five-star reviews.
Who is a heating contractor?
A heating contractor is a licensed tradesperson or company that installs, repairs, and maintains home heating systems such as furnaces, heat pumps, and boilers. Most also handle air conditioning and ventilation.
What is the major disadvantage of a heat pump?
Heat pumps lose some efficiency in very cold temperatures and may rely on backup heat during deep freezes. Modern cold-climate models handle Eastside winters well, and pairing one with a gas furnace removes the concern entirely. The upfront cost is also higher than that of a basic furnace, though lower energy bills help offset it.
How often should my furnace be cleaned and inspected?
Once a year, ideally in early fall before the heating season begins. Annual service keeps your furnace efficient, protects your warranty, and includes safety checks, such as carbon monoxide testing.
How long does a new furnace installation take?
Most furnace replacements are finished in one day. Projects that add a heat pump, new ductwork, or a fuel conversion can take longer, and we'll give you a clear timeline up front.
Are ductless heat pumps a good option in Issaquah?
Yes, especially for homes without ductwork or for rooms that never feel comfortable, like bonus rooms and additions. They heat and cool efficiently and let you control each zone separately.
Do you offer financing for heating and cooling systems?
Yes. We offer GreenSky financing for new furnaces, heat pumps, and air conditioners. The application is quick and uses a soft credit check.
