  • This field is for validation purposes and should be left unchanged.


When your boiler or furnace is on the fritz, it robs your comfort and productivity—and may even be a safety risk. With over 135 years of experience, McQuillan Brothers quickly diagnoses your heating problem—or installs new equipment that delivers high-efficiency performance for many winters to come.


Ignoring a small plumbing issue now can lead to expensive, intrusive repairs later. Remember the last time that “little plumbing problem” brought your whole house to a standstill? McQuillan Brothers offers prompt plumbing expertise at competitive pricing, so you can get your schedule back on track.

Air Conditioning

AC breakdowns seem to show up at the worst times: during a record-breaking heat wave or when guests arrive. Masters of troubleshooting, McQuillan Brothers technicians are available 24/7 to pinpoint your AC issue and recommend fast, cost-effective ways to keep your cool, such as high-velocity HVAC systems.

Home Care Club

When you join the Home Care Club, you’ll take the first step to proactive home maintenance and heating, cooling and plumbing savings. This affordable membership gives you three free visits a year, along with priority scheduling when your HVAC or plumbing system fails. It pays for itself in just one service call!

A Legacy of Happy Customers

  • “I came home that night after work and couldn’t even tell the technician had been there, with the exception that the new heater was working just fine. I think the area was cleaner than before he got there. Amazing.”

    — Chip M., Buzz Box
  • “…Matt was pleasant and prompt and gave us a very competitive bid. Technicians removed our old boiler and water heater and installed the new equipment. They were really patient with our questions and professional about their work.”

    — Julia F., Facebook
  • “The tech came out to clear a root blockage from our sewer. He was prompt, friendly and helpful. He did not try to sell us unnecessary fixes. He left us feeling confident that our pipes were clear and would be for a long time.”

    — JoAnne P., Facebook
