Keep Your Home Heating Systems Operating

  • Regularly replace air filters. Dirty filters increase energy costs, compromise air quality and can cause a furnace to shut down.
  • Ensure professional maintenance is done at least annually. Regular maintenance is actually required to preserve manufacturer warranty.
  • Do not store items around your furnace or outdoor unit. There should be unobstructed space around all equipment.
  • Install a web enabled thermostat.

“Our old boiler stopped working the other day. We called several places, but none of them could come the same day. I called MM Comfort Systems, and they had someone here in less than an hour. Within a half-hour our heater was up and running again. Awesome!”
“My best friend's heater blew up during a cold spell last month. After they called me in a panic, I contacted MM and they took care of everything right away. My friend was happy with the service and was amazed by how quickly they solved the problem.”
“Adam responded to our call today, and since it was snowy he was unable to drive up the hill to our house. No problem: He walked up. He was cheerful when he arrived and went right to work. He was confident, knowledgeable and clearly skilled. Bravo, Adam.”
“We were so pleased with the service we received. Jonathan was extremely helpful, professional and capable. We were VERY impressed. Thank you”
