Why You Should Schedule Furnace Maintenance

Scheduling furnace maintenance will have it ready for the cold season so it can meet the demands regardless of the forecast. A specialist can make repairs and perform a service check, i.e., replace the filters, lubricate all moving parts, and remove debris. 

Benefits of booking annual furnace maintenance include:

Lower Heating Costs

Inefficient furnaces consume more fuel if your thermostat temperature does not match the room temperature, which our specialists can correct.

Save Electricity

Fuel and power differ, but furnaces and HVACs rely on electricity to push air into your home. Our technician can stop your system from powering on and off frequently, which raises energy costs.

Extend the Life Span of Your Furnace

While furnaces last 15 to 20 years with service, older systems may need more tune-ups and repair work. However, if a replacement is cheaper, we will help you find one that matches your heating needs and budget.

Professional Furnace Tune-Ups

If your furnace makes noise or smells, let our experts inspect and diagnose your system. A professional HVAC company will keep your heater running optimally and alert you to any necessary repairs so you can budget for them.

Signs your furnace needs service include:

  • Weird or strange noises
  • Corrosion or rust
  • Short-cycling

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
