Special thanks to Don and Cameron for their thorough annual maintenance on our LG heat pump. Above and beyond the call, ensuring condensation water drained properly - completely ready for the summer. Many thanks.

I had my first yearly maintenance done after installing heat pumps last year. I had to write this review because I was so impressed by the technician, Eydin, who did the maintenance. Very pleasant, very knowledgeable, and was able to do everything quickly and efficiently, explaining things along the way. I learned so much!

Dual Heating + Cooling Maintenance Packages

If you haven’t had an HVAC tune-up in the past 6 months, why not schedule it now? Endless Energy offers 3 convenient packages to our Massachusetts customers.

Each package includes winterizing the AC condenser:

Regular Maintenance Boosts HVAC Efficiency

Cooling and heating systems consume a significant amount of electricity. If well-maintained, they use much less power, so you save on utilities every month.

A clogged filter, blocked drain line, or poor airflow are just a few problems that can reduce efficiency. Tune-ups address small issues before they get worse. They prevent costly repairs and can also extend your HVAC system’s lifespan.

Have you been told to schedule AC service in the spring and furnace maintenance in the fall? The truth is, you can schedule a tune-up anytime.

Benefits of combined maintenance:

  • One service call for both systems
  • Fewer surprises throughout the year
  • Reliable heating and cooling

AC + Gas Furnace Preventative Maintenance

When getting your gas furnace ready for winter, we take the following steps:

  • Inspect for gas and carbon monoxide leaks.
  • Test the limit switch and other safety devices.
  • Check the flue pipe for clogs, leaks, or corrosion.
  • Test smoke and carbon monoxide detectors.
  • Inspect the blower motor, burner assembly, and electrical connections.
  • Clear the condensate line if necessary.
  • Inspect the air filter (replacement costs extra).

AC + Heat Pump Preventative Maintenance

  • Check and clean the air filter.
  • Rinse the outdoor and indoor coils.
  • Measure refrigerant levels.
  • Perform leak detection and repair.
  • Inspect/lubricate the motor and belt.
  • Test the defrost cycle and auxiliary heat system.
  • Cycle the heat pump to test performance.

In the same visit as your AC tune-up, we get your heat pump winter-ready:

AC + Boiler Preventative Maintenance

  • Inspect the unit for leaks, obstructions, and vibrations.
  • Check for debris in the venting system.
  • Inspect the flame for proper color, soot, or damage.
  • Ensure water levels are within the manufacturer’s 
  • recommendations.
  • Check the low water cut-off and automatic low water 
  • cut-off systems.
  • Inspect the fuel supply system for leaks or blockages.
  • Ensure the combustion system has proper airflow.

When evaluating your boiler, our technicians:

*Each of these promotions can also add a hot water heater flush (must be during the same maintenance appointment) for an additional $99.95.
