McWilliams Heating, Cooling and Plumbing provides heating, ventilation and air conditioning (HVAC) services for residential and commercial customers. We offer HVAC maintenance, repair and installation of central systems as well as mini-split units, heat pumps and window units to help create a comfortable indoor environment.

Reduce the Risk of HVAC Break-Down

Proper HVAC maintenance is essential. A well-running system uses less energy, maintains adequate levels of humidity and delivers the proper temperature of conditioned air within your building. We offer annual service agreements that cover scheduled maintenance so that you know your system will work when the seasons change. Fall tune-ups ensure that your heating system is in good shape. Spring tune-ups ensure that the air conditioner functions properly. A well-maintained system reduces the possibility of breakdowns.

Tune-Ups Include

Cleaning the evaporator and condenser cabinets
Cleaning or replacing the filter
Ensuring that the pilots and ignitions of furnaces function properly
Inspecting the hood and housing of furnaces for leaks or corrosion
Checking for the presence of dangerous gasses like carbon monoxide
Inspecting wiring and electrical connections
Making sure the unit cycles on and off properly

  I had a leak in my water line at the horse barn along with a leak in my kitchen sink AND one of my AC units in my house with problems. Called McWilliams and got scheduled for repairmen to come out. I got 3 of the sweetest, smartest, most polite young men that DEFIANTLY KNEW THEIR JOBS!!! They are TAVO, Air Conditioner repair, and Ivan and Jonathan, Plumbers. I give all 3 5 STARS and whenever I need McWilliams again I will ask for these guys. THANKS GUYS
