Complete Comfort for Every Season

Every home has different comfort needs. We help homeowners across Seattle, Tacoma, and the Puget Sound compare system types based on layout, energy goals, lifestyle, and long-term value.

Why Upgrade Your Furnace?

If your furnace is 15+ years old, unreliable, noisy, or expensive to run, it may be time to consider repair or replacement. A newer high-efficiency furnace can improve heating performance, reduce operating costs, and deliver more consistent comfort throughout your home.

Why Choose a Heat Pump?

Heat pumps are a strong fit for Western Washington because they provide both heating and cooling in one system. They are ideal for homeowners who want energy-efficient comfort, lower utility use, and the opportunity to take advantage of available rebates and incentives.

Benefits of Ductless Systems

Ductless mini-splits are ideal for homes without existing ductwork, additions, remodeled spaces, or rooms that never seem to stay comfortable. They deliver targeted heating and cooling with room-by-room control and quiet, efficient performance.

Signs It’s Time for AC Service

If your air conditioner is blowing warm air, cooling unevenly, making strange noises, or struggling to keep up during hot weather, it may be time for professional service. Addressing issues early can help protect comfort and prevent larger repair problems later.

FREQUENTLY ASKED QUESTIONS

HVAC FAQs for Seattle, Tacoma & Puget Sound

How much does HVAC installation cost in the Seattle-Tacoma area?

HVAC installation costs vary based on home size, system type (furnace, heat pump, ductless), efficiency level, and whether electrical or ductwork upgrades are needed. Home Comfort Alliance provides free estimates, financing options, and help identifying local rebates to reduce upfront cost.

Should I repair or replace my furnace or AC?

If your system is older, needs frequent repairs, or has a major component failure, replacement is often more cost-effective long term. We’ll walk you through repair vs replacement options so you can make an informed decision. For heat pumps, see heat pump replacement.

What’s the difference between a furnace and a heat pump?

A furnace generates heat using gas or electricity. A heat pump transfers heat and provides both heating and cooling. In the Puget Sound climate, heat pumps are popular for efficiency, comfort, and rebate eligibility. Both need a yearly tune-up: see furnace maintenance and heat pump maintenance.

Do heat pumps work in cold Seattle winters?

Yes. Modern heat pumps are designed to perform well in our mild-to-cold winters when properly sized and installed. Some homes may include a backup heat option for added peace of mind.

How long does HVAC installation take?

Most HVAC installations are completed in 1 to 2 days, including removal, installation, testing, and cleanup. More complex projects involving electrical or duct modifications may take longer.

Do I need to upgrade my electrical panel for a heat pump?

Sometimes. Heat pumps and high-efficiency systems may require additional electrical capacity. We evaluate your panel during the estimate and handle upgrades if needed.

Do you offer same-day or emergency HVAC service?

We offer fast scheduling when available, especially for no-heat or no-cool situations. Availability depends on technician routing and demand, calling early helps. See our emergency service page.

What HVAC system is best for my home?

The best system depends on your home layout, existing ductwork, comfort goals, and budget. Central, ductless, and hybrid systems each have advantages, we’ll recommend the best fit for your space.

Are there rebates or incentives for HVAC upgrades in Washington?

Many Washington homeowners qualify for utility and regional incentives, especially for heat pump installations. Eligibility depends on location, utility provider, and system type, we help identify applicable rebates during your estimate.

  Allen was on time, friendly, and professional. He recommended a surge protector for our heat pump, explaining how it was much less expensive than most of the electrical systems within our unit. Will have Home Comfort install it shortly.

  I was SO relieved to be able to get an appointment same day to address my faulty furnace. The technician, Allen Walker, was on time, very knowledgeable, patient, and a pleasure to work with. I hope to see him again next year for furnace maintenance. Thanks again, Allen! Appreciate you taking the time to explain all the things.

  Technician showed within the designated time period. Told me the order of how the componants would be serviced. He was very friendly and his truck did not block any of my vehicles (that was thoughtful). He outlined potential upgrades to make my warranty worth more (still thinking on those). Company texted well b4 Tech came, so i was ready and he completed tasks and left everything in order with no trash and a brief oral report of conditions, followed by written one in an email. JKT, a satisfied customer.

  The heating/cooling unit servicing one part of our home stopped working.  I called Home Comfort Alliance, Bremerton, who we have used for many years to service our units.  They scheduled next day service, and I was thrilled with the timely response.  They sent out Brad, their top troubleshooter.  He not only fixed the unit that stopped working but also performed the six month service on the other two units; changed the filters and provided a report of his findings.  I cannot recommend Home Comfort Alliance enough.  They are responsive and knowledgeable about the services they perform.  I appreciate that Home Comfort has a top-notch service person on their staff who can investigate and solve issues on complex systems.

  Bradley is simply the best.  He installed the new motor on our heating unit quickly and proficiently. He is very competent and very knowledgeable.  Truly a pleasure to work with.  Kudos also go to Home comfort alliance because they generously assumed the cost of shipping the motor via air freight so that I would have it as soon as possible. Bradley and his company deserve the highest possible rating.

He did a thorough inspection, explained all my options and clearly answered all my questions.  Mike was very congenial and knowledgeable--an excellent person to work with.   He now will be providing me quotes per my various options.  In addition, my dog really liked him--an important seal of approval!

  Sam and Mario did a fantastic job installing our new gas furnace. They demonstrated great customer service and the attention to detail: they put new gas valve, power supply for in-duct purifier, condensing water pump, new filter cabinet + filter that Sam had to step out to shop for, etc. They even upgraded our thermostat's wiring to match the new 2-stage furnace (without hard-defining a timed cutoff on the filter board). I appreciate very much that they did these without us having to ask or monitor, but rather to do a high-quality job (they worked for 6+ hours and took care of everything!). Thank you folks for the great job!
We also a good experience with the initial consultant (Vince) who did a thorough job of estimating our new furnace specs. We found them through Costco (Lennox). Our pricing included the 15% costco cash card; their overall quote was reasonable and competitive as well (lower than some of the other quotes we had). We are very happy with the install and service, and would happily recommend this business.
