Frequently Asked
Questions

We answered some of your questions regarding permits, inspections, warranties and more!
Why can't I find the correct size furnace filter at my local home improvement store?

The filter installed with your Home Comfort Alliance furnace is larger and made from higher-quality materials than disposable filters found in retail stores. Filter replacement is automatically included as part of our Planned Maintenance Agreement – the most cost effective way to keep your system in efficient working condition. Replacement filters can also be purchased directly from Home Comfort Alliance. We maintain inventory of the most common sizes. Call 425-645-0404 and ask for service or email us.

Where can I get parts for my comfort equipment?

Your experts at Home Comfort Alliance are the best resource for identifying and supplying the correct, current parts for your system, as well as pricing and availability.

Which comfort equipment will best fit my home?

There are many factors that affect the sizing and specifications of your system, including square footage, insulation, window surface and configuration, geographic location of your home, duct sizing and arrangement, and many others. Your Home Comfort Alliance design consultant can perform an in-home load analysis to determine which equipment combinations will perfectly suit your home and your family’s needs.

What does my warranty cover?

Home Comfort Alliance provides a full parts and labor defects warranty for one year from date of installation. Manufacturer equipment / parts warranties vary and are typically longer than one year. Carrier now offers an industry-leading twenty year warranty on secondary heat exchangers on their high efficiency furnaces. Home Comfort Alliance will help to ensure you obtain maximum benefit from any applicable manufacturer warranty.

How much will a new system cost?

There is is very wide range of system sizes and capabilities.  On the lowest end, a small simple furnace replacement is about $3,000. On the higher end, a larger zoned Hybrid system (heat and a/c) with leading edge Indoor air Quality capabilities would be an investment of around $20,000. Your Home Comfort Alliance Consultant will work with you to develop a system appropriate for your needs.

Why is the SEER rating on the Energy Guide different than what my dealer quoted?

Each split system cooling unit has a nominal SEER rating. This rating can be increased with the upgrade of the indoor unit. The SEER rating of a system is derived based on the combination of equipment installed in the home. The outdoor equipment (heat pump or air conditioner), as well as the indoor equipment (evaporator coil and furnace, or air handler), play a vital role in the rating. Please see your Home Comfort Alliance representative for the information.

What is the life expectancy of my unit?

In the Pacific NW, properly maintained, furnaces, heat pumps, air conditioners and hot water heaters have normal useful lives of 10 – 15 years.

I am an Architect and need application/specification information so that I can specify Carrier products... where do I obtain this information?

Home Comfort Alliance can provide you with the specifications, and can also set you up to access the Carrier HVACpartners web site so that you can access the information yourself. If you are seeking specifications on older equipment, so as to specify something similar, it will be helpful if you have the model and serial number available.

How do I program my thermostat?

If you know what type of thermostat you have, one of our service coordinators can send you the manufacturer’s instructions.  If you do not know what type of thermostat you have, we may schedule a service visit for a technician to assist you.

The inspector came but did not say anything, does he have to sign off my permit?

Sign offs for permit inspections are done electronically.  Should any items require correction, the inspector will inform you of that and then you will want to inform us immediately, so that we may address it.

Do I have to schedule my permits and do I have to be home?

Your installation coordinators will provide you with the information for scheduling the required inspections and what to expect.  You will need to be at home for the inspection visit.

What is the warranty on my furnace, odu and coil?

Our service coordinators can assist you in locating the model and serial number for your equipment and contacting the manufacturer to confirm the warranty information.

What our Customers are Saying!

Upgraded to a new furnace and air conditioning system through Costco Home Services. The MM Comfort System installers, Lamont and Qushawan, did an outstanding job. They were on time, courteous and did a nice job of cleaning up after installation. The furnace and air conditioning units were installed on separate dates due to availability of equipment. A week after I received my estimate, my original furnace died. The folks at MM Comfort Systems moved my furnace installation up to that same week. I really appreciated their rapid response. The new furnace is much nicer than the old furnace and made the holidays really comfortable. I am looking forward to having air conditioning for the first time this summer in my home. It will be a welcome relief from last summer. If you need a new furnace or air conditioning system, call them first.

This company was great to work with installing our A/C from start to finish. Steve the rep was always available when we had a question and the installers, Ruslan and Dallas were professional, friendly and efficient. When we had to move the location of the AC unit at the last minute, Dallas jumped in and helped dig up a stubborn beast of a shrub. Installing the unit in the attic wasn't fun but they did it with humor and without complaint and they made sure everything was cleaned up before they left. Great follow up by Hannah handling the permits. We didn't have to do anything! Would highly recommend this company.

Throughout the process, the MM comfort system is very responsive in responding to my inquiry and request.

MM Comfort Systems replaced my old furnace with a new one. What a great team -- professional, caring, and responsive, including the technicians and the administrative staff. Despite unexpected problems (not their fault), which required repeated visits, they worked hard to make sure the installation was successful. I would recommend this company to anyone.

We had an AC unit installed in December 2021. The price was significantly lower than quotes we received from competitors and the installers were professional. We will be ready for next summers heatwave.

Our heat pump failed the night before the big heat wave back in late June. We were facing the prospect of having to search for a place to stay cool since all the HVAC companies we called gave us appointment times several days and even weeks away. We called Sullivan late Friday evening and they had a technician here Saturday morning and he fixed the heat pump in about 30 minutes. We needed a part and Arnold the technician had it in the truck! Go figure. Our external thermometer got up to 113 degrees two days later. I can't speak highly enough of this company. I can't imagine the misery and discomfort they saved us and possibly the death of my old dog from the heat. Thank you Sullivan Heating & Cooling.

Travis our service tech was friendly and knowledgeable, he explained everything he was doing and why. Fixed the problem and did not leave until he made sure everything was working correctly. Definitely will use Sullivan Heating and Cooling again in the future.

Sullivan installed our new heating system this year and worked with us so the thermostat settings are right. We have been so grateful during this time of hot temperatures we have the service. They do a great job!

My heat pump broke down unexpectedly the night before a record heat wave was expected. I called just about every HVAC company I could find and no one was willing to book an appointment for at least several days out. Most were several weeks. But Sullivan returned my after hours phone call within minutes and had a tech come to my house within a few hours and quickly made the repair. Their work was great, and their prices were fair. These guys are superheros and I can't recommend them highly enough.

I did some research into how heat pumps worked prior to calling for estimates. Two other companies came out before Sullivan, both lied to me. Sullivan was honest and followed through beautifully, my only regret is that I had forgot to get a bit of cash to tip the installation crew!
