Our High-Quality Air Conditioning Units in Redmond, 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 Redmond 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 Redmond home.
Ductless systems can be installed in places where conventional ducted systems cannot go or are an ideal complement to your Redmond 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 Redmond 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 Redmond 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 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.

our HVAC system hadn't had service in 7 years. Isaac was great! He was professional and thorough and did a lot of problem solving. Happy to sign up for annual service with Home Comfort Alliance - and hopefully get Isaac back! We’ve now had Brad out to fix some connectivity issues in our two HVAC zones. He really knows what he’s doing. Solved the problems now that we need heat for the winter months They sent him out the day after I called!

Okay.. two people to rave about.. Chad Galino (electrician) and Kyle Callahan (heat pump/furnace specialist). We used this company under its old name for our heat pump for years and they were great. These two guys were awesome. Chad walked me through the house and we discussed potential issues/problems, what I can do during a small remodel, my electrical panel and ideas for installation of my light fixtures. He knew his stuff. He'll be installing light fixtures and working on my electric panel soon. Kyle.. he educated me on my furnace and discussed how I will know when I need a new one (mine is old) and what that looks like. He had great suggestions and helped me feel confident about what I need to do when. Also, he serviced my furnace and heat pump and educated me about my heat pump. I highly recommend both men and will tell all of my friends.

I've used Home Comfort Alliance (previously Sullivan's) in Bremerton for a number of years now for my gas furnace and more recently my Heat Pump/AC for maintenance and repairs when needed. Technician Dan, recently provided annual maintenance on both systems in October and as usual, provided great service! It's great to go into the weather months with confidence that these systems have been checked out and are ready to go!

Wonderful experience. A technician (Dan) was here the morning after I called. He worked and worried over the problem with our furnace, came to a possible fix, ordered the part so he could get it next day and successfully got the furnace up and running on day two. His determination to find the problem and then fix it was phenomenal. Definitely my hero. And Tonya stayed on it also. Bravo to all!

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.

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.
