When to Get Professional Furnace Repairs

When your furnace fails during winter, it’s not just an inconvenience—it’s dangerous. Here are some common signs that you might need our furnace repair services:

  • No heat: If your furnace isn’t producing heat, it could be due to issues with the thermostat, pilot light, or ignition system. Our technicians can quickly identify and resolve the problem.
  • Strange noises: Unusual sounds like banging, rattling, or squealing can indicate mechanical problems or loose components. We can inspect and repair your furnace to prevent further damage.
  • Frequent cycling: If your furnace turns on and off frequently, it may be struggling with thermostat issues, airflow problems, or a malfunctioning component. Our team can diagnose and fix the issue to improve efficiency.
  • High energy bills: A sudden increase in heating costs can signal that your furnace is working harder than it should. We perform efficiency checks and necessary repairs to help reduce your energy bills.
  • Strange smells: Bad or unusual smells from your heating system are signs that it needs immediate attention. Metallic smells, burning dust, or the smell of burning plastic can all mean that your furnace needs servicing.

We just had a service call for a water heater issue and SAC went beyond our expectations by responding with a quick and high quality oriented solution. We have used them in the past for heating and A/C equipment issues and installations and have had a similarly excellent experience. I recommend them without any reservations.

I used SAC for checking my AC & Furnace. The technician Steve was very knowledgeable and professional. He explained step by step what he was doing and showed me all the possible future issues that I should keep my eyes on them. No pressure at all to do extra repair or fixing. I strongly recommend SAC for any heating and cooling job. They are one of the top.
