Everett Residential HVAC Contractor

Comprehensive HVAC Solutions in Snohomish County

It’s easy to take our air conditioning and heating systems for granted. Just set the thermostat for some cozy warmth in the winter or some refreshing coolness in the summer. But an HVAC system, like anything else, doesn’t run on its own, even if it can seem that way sometimes. Legacy One Heating offers reliable services that homeowners can depend on.

Our Everett residential HVAC team serves customers throughout Seattle, Kirkland, and beyond. We stand by our work with a guarantee of satisfaction, and our bilingual team works with both English and Spanish-speaking communities.

Our Residential HVAC Services

Our service is end-to-end, through the life of a unit. We handle everything from repair to replacement to routine maintenance.


When an HVAC system fails, our professional and experienced technicians are available to diagnose and repair it as quickly as possible. Our repair services cover a wide range of issues, including:

  • Faulty thermostats
  • Blower motor failures
  • Ductwork malfunctions
  • Refrigerant leaks
  • Electrical control breakdowns
  • Compressor problems

There are some telltale signs that repair work is needed. The most basic is when the temperature in the house won’t align with what the thermostat has been set at. Pooling water around the unit or clanking sounds from inside of it are other indicators. The sooner our Everett residential HVAC techs can get out there and get to work, the better the chances of keeping repair costs limited.


We’ve all been through the decision that comes up with our cars—do you keep pouring money into repair, or is it just easier, and more cost-effective, to buy a new one? The same question has to be dealt with regarding HVAC units.

What homeowners need most is reliable information. How long can their current unit last and what should they expect from it? What’s the best option for a new system? Legacy One Heating was founded in 2016 precisely because we wanted to be able to give our customers honest recommendations and not just be in a perpetual game of upsell. As a small business, our long-term reputation is more valuable than a short-term sale. So, when we give people advice, they can be confident we’re basing that counsel on their own best interests.

Routine Maintenance 

Preventive measures are always better than emergency solutions. This is why we offer ongoing maintenance services for your Everett residential HVAC system. Our HVAC maintenance plans include regular inspections, tidy-ups, cleaning, and filter changes that ensure your system runs smoothly and reliably throughout the year. This includes:

  • Checking connections and tightening electrical components
  • Cleaning the coils and replacing the filter
  • Add refrigerant, if necessary
  • Checking for any leaks or other signs of damage
  • Testing all safety controls
  • Inspecting the heat exchanger for damages

The easiest problems to fix are the ones that get caught early or, even better, never happen at all. That’s what our routine inspection program is aiming for.
