Our High-Quality
Air Conditioning & Heating Units

Split Systems
The most typical cooling and heating systems are split systems and commonly referred to as central air conditioning. They are comprised of an indoor unit for heating and an outdoor unit for cooling.
Hybrid Systems
A hybrid system is also a central air system, but the outdoor unit is a heat pump. The heat pump supports both cooling and heating allowing the indoor gas furnace to be a backup source of heat. It’s an energy-efficient and cost-effective way to cool and heat your home.
Ductless Systems
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.

Heating Installation Done Right

Since 1977, we at MM Comfort Systems have been outfitting houses in King, Pierce, and Snohomish County with furnaces that last. Our locally owned business is familiar with the ins and outs of furnace replacement work, and there are quite a few ways in which we outshine the competition. While it's always great to save the furnace that you have, some units are simply beyond repair. When it comes time to replace your furnace, count on us at MM Comfort Systems to deliver results that you'll be proud of.

Choosing Between An Air Conditioner & A Heat Pump

Need help deciding what is best for you?
Consider upfront cost

While a heat pump system has a lower cost indoor unit, the outdoor unit can come with a higher upfront cost compared to an air conditioner. When considering cost, it is important to understand the total costs to install a system that can both heat and cool your home properly. Your MM Comfort Consultant can help determine all of the costs involved.

Energy efficiency/cost of operation

A heat pump system provides energy-efficient heating using electricity, so when the temperature is moderately cold outdoors, they can be less costly to operate compared to systems that use more expensive heating fuel sources such as natural gas, oil, or propane.  As temperatures drop below freezing, the heat pump requires more energy to maintain comfort inside, reducing efficiency and increasing your electric bill.  This problem is solved by pairing a heat pump with a furnace, thus creating a Hybrid Heat system. However, due to the higher initial cost for the heat pump unit, a hybrid system may be more expensive than a more commonly paired system of an air conditioner and furnace.

The energy efficiency rating for both air conditioners and heat pumps when in cooling mode is expressed as SEER ratings. The efficiency of a heat pump when in heat mode is expressed as HSPF.  The higher the rating for SEER or HSPF, the more efficient the unit.   However, the energy efficiency and cost to operate really comes down to location.  In areas with more moderate temperatures, a heat pump is a better option for efficient heating than in places that have very cold winter temperatures.

Life expectancy

While the longevity of an HVAC system is determined by several variables, AC units typically last longer than heat pumps.  Because heat pumps both heat and cools a home, they are used year-round.  Air conditioners get a rest during cooler months when a separate heat source is used to heat the home.  However, even though a heat pump may have a shorter life expectancy that can be offset by its ability to deliver efficient, money-saving heating during milder winter weather.  The life expectancy of your heat pump or air conditioning system can be maximized and kept running at its maximum energy efficiency by having the expert technicians at MM Comfort Systems maintain your system regularly.   Comfort Club members never have to think about it!
