Furnace Repair

When a furnace quits during a Lamar winter, it's an emergency, not an inconvenience. January nights here average in the mid-teens, and the area's record low is –30°F. Evergreen Electrical & Mechanical repairs gas, propane and electric furnaces throughout Prowers County and the surrounding region. You get the same local crew that homeowners, ranchers and businesses already trust with their electrical work.

Why call an electrical contractor for furnace repair?


A lot of "no heat" calls turn out to be electrical. Common culprits are a failed igniter, a dirty flame sensor, a bad control board, a blower motor or capacitor, a tripped limit switch, or a thermostat wiring fault. Our technicians troubleshoot the furnace and the circuit feeding it in one visit. You don't have to wait on a second contractor to find out the breaker or wiring was the problem.

Furnace problems we fix

  • Furnace won't turn on, or there's no heat at all
  • Furnace running but blowing cold air
  • Short cycling (turning on and off over and over)
  • Igniter, pilot light and flame sensor failures
  • Blower motors, capacitors and belts
  • Control boards, limit switches and pressure switches
  • Thermostat problems, including smart thermostat setup
  • Banging, squealing, rattling or burning smells
  • Uneven heat, cold rooms or rising heating bills
  • Propane (LP) furnaces on farms and rural properties
  • Electric furnaces and backup heat strips

Signs your furnace needs repair


Call before a small problem becomes a no-heat night. Watch for these warning signs:

  • The furnace takes longer to heat the house than it used to
  • You hear new noises when it starts or shuts off
  • The burner flame looks yellow instead of blue
  • Your heating bill jumps without a change in weather or usage
  • The carbon monoxide alarm sounds (leave the house first, then call)

How our furnace repair works

  • Call or request service. Tell us what the furnace is doing, and we'll schedule the earliest available visit.
  • Full diagnosis. We find the cause and check safety items: venting, gas connections, burners, heat exchanger and electrical supply.
  • Clear options. We explain what's wrong and what it will cost before any work starts.
  • Repair and test. We fix the problem and run the furnace through a full heating cycle.
  • Clean up. We leave the work area the way we found it.

Gas, propane and electric furnaces

In town, most Lamar homes heat with natural gas from Atmos Energy. Out on farms and ranches, propane furnaces are common, and some homes and shops use electric furnaces or heat pumps with electric backup heat. We service all three, including the wiring, breakers and thermostats that control them.

Emergency furnace repair

We answer no-heat calls 24/7. No heat when it's below freezing puts pipes, livestock water and people at risk. Call (719) 336-9111 and we'll get you warm as fast as we can.

Safety callout (style as a highlighted box): If you smell gas, don't touch any switches. Leave the building right away. From a safe distance, call 911 and Atmos Energy's 24-hour emergency line at 1-866-322-8667.

Repair or replace?

Repair is usually the right call for a furnace that's under about 15 years old and has been reliable. Replacement starts to make more sense when the furnace is older, needs frequent repairs, or has a cracked heat exchanger. We'll give you an honest recommendation either way.

Prevent breakdowns with a maintenance agreement

A fall tune-up catches worn parts before the first cold snap. Our residential and commercial maintenance agreements give you scheduled service and top-priority response. Ask about a maintenance agreement.

Frequently Asked Questions

It depends on the part and the time needed. Replacing a flame sensor costs far less than replacing a blower motor or control board. We diagnose the problem first and give you the price before any work begins.

Yes, we're available 24/7. Call (719) 336-9111 any time your furnace stops working, and we'll get a technician to you as quickly as possible.

Yes. We repair propane (LP) furnaces as well as natural gas and electric furnaces, including on farms and ranches outside of town.

Common causes include a dirty flame sensor, a failed igniter, a clogged filter tripping the limit switch, or a thermostat set to "fan on." If changing the filter and checking the thermostat doesn't fix it, call us for a diagnosis.

Once a year, ideally in early fall before heating season. Annual service keeps the furnace efficient, catches worn parts early and checks for safety problems such as cracked heat exchangers.
