Our High-Quality Air Conditioning Units in Seattle, WA

A gas or electric furnace is the main component of a traditional heating system and may be combined with an air conditioner in your Seattle property for a complete heating and cooling system. This combination is referred to as a split system.
A hybrid heating and cooling system is a variation to the traditional split system. It includes an outdoor heat pump that allows the option of electricity-fueled heating and cooling in addition to a gas furnace. It’s an energy-efficient and cost-effective way to heat and cool your Seattle home.
Ductless systems can be installed in places where conventional ducted systems cannot go or are an ideal complement to your home’s current ducted system. They can function as an air conditioner for cooling only or as a heat pump for both cooling and heating.

Air conditioning systems come in different types which affect the efficiency, comfort level, and noise level of a system in your Seattle property.
Single-Stage
A single-stage unit means its operating speed is either on or off.
Two-Stage
A Two-stage unit means it operates on either high or low. The low setting is adequate to meet most household cooling demands about 80% of the time, providing even temperatures. On hotter days, it can leverage the high level of operation to maintain comfort levels. Two-stage systems are typically quieter and more efficient for your Seattle property than a single-stage unit.
Multi-Stage
A Multi-stage unit has a range of operation and therefore the most precise temperature control and best comfort. These variable speed units are the quietest and offer the most energy savings.

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.

Mike from Home Comfort Alliance came today to gather information in aid of providing a quote for replacing my furnace and adding AC through Costco's many services. 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.
