Why can't I find the correct size furnace filter at my local home improvement store?

The filter installed with your MM Comfort Systems 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 MM Comfort Systems. We maintain an on hand inventory of the most common sizes. Call 425 881-7920 and ask for parts or email us at service@mmcomfortsystems.com.

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 MM Comfort Systems 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?

MM Comfort Systems 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. MM Comfort Systems will help to ensure you obtain maximum benefit from any applicable manufacturer warranty.

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 MM Comfort Systems 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?

MM Comfort Systems 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.
