Heater Maintenance

Properly maintained heating equipment is more efficient and will last longer than a system that is not regularly maintained. You can save thousands of dollars with regular heater maintenance because your system will operate at peak performance, which reduces operating costs. A worn motor or other problem can be diagnosed and the faulty components replaced before your heater fails on a cold winter day.

AC Maintenance

Regular preventative AC maintenance offers several benefits. Well maintained equipment improves efficiency, decreases operating costs, prevents equipment breakdown, and leads to a longer-lasting air conditioner. In addition, problems can be detected early and fixed, which prevents equipment failure on a hot summer day.

Our comprehensive maintenance service includes:

  • Checking air filtration systems
  • Operations sequence checks
  • Checking blower operation
  • Voltage checks
  • Checking operating pressures and temperatures
  • Inspecting condenser and evaporator coils
  • Electrical connection inspections
  • Inspecting and flushing drain lines
  • Inspecting outdoor fan motors, recording AMP draw, and lubricating
  • Checking refrigerant level
  • Safety control checks
  • Checking capacitors, motors, and lubrication
  • Checking contractors and relays

      After our technician has completed the inspection and maintenance, you will be provided with a full written report containing details about any recommendations and options for repairing problems that may have been discovered during the maintenance inspection. If a repair is needed, we offer upfront pricing, so you will know the cost of the repair before the work begins.
