About Us
read moreMM Comfort Systems got its start back in 1977 as B&B Heating. Within just a few years, their exceptional reputation led them to be recognized as the National Residential HVAC Contractor of the Year. In 1993 they joined with a leading Seattle mechanical contractor, also nationally honored for their history of quality dating back to 1965. The name MM Comfort Systems was established when key employees purchased the residential portion of the company in 2001. A few years later, building on 51 years of expertise in serving residents of Tacoma and Pierce county, Heritage Heating and Rite Way Gas became part of MM Comfort Systems and a second location was opened in Sumner.
Water Heater Services
read moreThe most common sign that there's a problem in your hot water heater is if you notice your hot water supply dropping sharply or if it doesn't last nearly as long as it once did. The easiest way to keep your water heater running to its maximum performance is with regular maintenance and sediment removal. Over time, sediment that builds up in your tank can include debris from your pipes or hard metals like iron and lead. It's not unsafe, but it can reduce the efficiency of your system substantially.
Air Conditioning Installation
read moreA gas or electric furnace is the main component of a traditional heating system and may be combined with an air conditioner 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 home.
Heating & Cooling System Types
read moreA Two-stage unit means it operates on either high or low. The low setting is adequate to meet most household comfort 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.
Air Duct Cleaning
read moreCleaning air ducts can help to eliminate some of the most common pollutants found in homes, but there are additional benefits as well. When the ducts become too dirty and debris begins to block the flow of air through the ducts, your air conditioning and heating equipment may not run as effectively as it should. It may take longer for your home to reach the proper temperature, which can wear down components and increase energy costs. The process begins with an inspection of the entire air duct system prior to cleaning.
Indoor Air Quality Service
read moreSimple filtration through a 1 or 2-inch filter used with your furnace or air conditioner is a low-cost, entry-level solution for protecting your equipment. Enhanced filters that are 4-6 inches can provide a higher Merv rating to allow for cleaner air. Enhanced filtration can be achieved thru the use of an electronic air cleaner or air purifier(sometimes known as an air scrubber). These use electricity to capture and disinfect pollutants in the air. It attaches to your HVAC system reducing odors, dust, and eliminating harmful contaminants both in the air and on the surfaces of your home.
