What's Going Wrong?

Signs Your Furnace May Need Repair

Heating problems do not always begin with a complete breakdown. These are common warning signs that it is time to have your system checked.

No Heat

Your furnace runs but the house stays cold, or the system will not start at all.

Weak or Uneven Airflow

Some rooms stay cold while others are comfortable, or airflow from the vents feels unusually weak.

Strange Noises

Banging, rattling, squealing, grinding, or repeated clicking can point to worn or failing components.

Short Cycling

The furnace repeatedly starts and stops instead of completing normal heating cycles.

Unexpected Energy Use

A sudden increase in heating costs can be a sign that your system is working harder than it should.

Thermostat Problems

The temperature does not match the thermostat setting or the system does not respond correctly.

  • Ignition and burner repairs for common gas-furnace starting and heating problems.
  • Blower motor and airflow repairs when heated air is not moving through the home correctly.
  • Thermostat and control repairs for inaccurate temperatures or systems that do not respond properly.
  • Electrical component testing and repair for switches, relays, controls, motors, and related components.
  • Safety and operating checks to verify the system is functioning properly after the repair.
  • Repair for all makes and models whether we originally installed the equipment or not.
Experienced With Your Equipment

We Repair All Makes & Models

Armstrong's is proud to work with Carrier equipment, but your furnace does not have to be a Carrier system for us to help.

Our technicians repair and maintain heating equipment from all major manufacturers. That means you can call Armstrong's even if another company installed your furnace or you recently moved into a home with an unfamiliar system.

If a repair no longer makes financial sense, we can also explain replacement options without pressuring you into equipment you do not need.

Repair or Replace?

We'll Help You Understand the Options

Many furnace problems can be repaired. But if a system is older, has a history of repeated breakdowns, or needs a major repair, replacement may sometimes be the better long-term decision.

Our job is to give you the information you need to make that choice. We can discuss the condition of the equipment, the repair involved, and whether it makes sense to keep investing in the existing system.

Learn About Furnace Replacement

A repair may make sense when:

  • The system is otherwise in good condition.
  • The needed repair is relatively straightforward.
  • Breakdowns have not become a recurring problem.
  • The equipment still meets your home's comfort needs.

Common Questions

Heating Repair FAQ

A few common questions homeowners have when their furnace is not working properly.

Do you repair furnaces you did not install?

Yes. Armstrong's repairs and maintains all makes and models, whether we installed the equipment or another contractor did.

What should I check before calling for furnace repair?

Make sure the thermostat is set to heat, confirm the system has power, and check whether the air filter is severely clogged. If the system still will not operate normally, give us a call.

Can you repair thermostat problems?

Yes. Thermostats, sensors, controls, wiring, and other electrical components can all affect how a heating system operates and can be included in the diagnostic process.

What if my furnace is too old to repair?

If the system needs a major repair or replacement is likely to be the better value, we can explain your options and provide information on a new heating system.
