HVAC Preventive Maintenance

McWilliams & Son Heating and Air Conditioning provides heating, ventilation and air conditioning (HVAC) services for residential and commercial customers in Nacogdoches, Lufkin and the surrounding East Texas area.

HVAC Maintenance

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
