Your Local Air Conditioning Company

GMC Heating & Cooling can handle any HVAC problems that arise. We understand that keeping you cool requires your systems to be in top shape, especially when it’s sweltering outside.

Our specialists cover Upland and the surrounding areas, so if you’re having problems with your HVAC system or need a new one, give us a call! We have the experience and skilled professionals to assist you with anything from selecting an HVAC system to installation and maintenance.

When Was The Last Time You Had Your Air Ducts Cleaned?

Heating, ventilation and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have the potential to affect health such as mold, fungi, bacteria, pollen, dust, and pet dander. What you don’t see CAN hurt you. Considering that most people spend about 80% of their time indoors, the risks to human health may be greater due to exposure to air pollution indoors rather than outside. The removal of contaminants from the HVAC system should be considered an essential step toward improving indoor air quality.

Air Duct Cleaning
For Residential & Commercial Properties

Heat pumps, like furnaces and boilers, require an annual service tune-up and cleaning in the fall. Our skilled specialist will first evaluate the ducts with video equipment to determine their condition and determine whether any repairs are required. The air intake as well as all registers are removed and cleaned completely. The Rotobrush system is used to clean the ducts. This helps to loosen all of the dirt and mold, which is then vacuumed away. After that, the ducts are sterilized with a fogger to destroy germs and mold, allowing you to breathe clean, healthy air in your house or place of work once more.

GMC Air Duct Cleaning offers a full service that includes:

  • Video Inspection
  • Duct Repairs
  • Duct Cleaning using the Rotobrush System
  • Air Duct Sanitization
  • Removal & Cleaning of all Registers and Air Intake Grill
  • Heating & Cooling System Check
  • Clean & Vacuum Furnace
  • Fit New Air Filter
  • Check AC Condensation Line
  • Clean AC Coil and Condensers
  • Dryer Vent Cleaning to reduce fire risk

Air Conditioning Maintenance & Repair

We repair and maintain all heating, air conditioning, and ventilation systems. An air conditioner’s filters, coils, and fins must be maintained on a regular basis if the machine is to work properly and efficiently over time. Air conditioning performance will continue to decline while energy usage will increase if simple maintenance is neglected. We offer services including:

  • AC and Heating Inspection and Repairs
  • Annual Inspection and Tuneup
  • AC Installation – New & Replacement
  • Furnace Installation – New & Replacement
  • Scheduled Maintenance
  • Air Duct Inspection, Repair, and Replacement
  • New Duct Installation

GMC can supply, fit, repair, service, and maintain all major brands of AC units and furnaces.
