Signs Your Heating System Needs Repair.
Heating problems don't always start with a complete system failure. Changes in performance, sound, airflow, or operating cycles may indicate that a component needs attention.

You don't need to diagnose it yourself. Tell us what you're experiencing, and we'll find the cause.
Find The Actual Cause
Heating Systems We Repair.
Mark Hill repairs several types of residential heating equipment throughout the Tulsa metro.
01
Gas Furnaces
Gas furnaces depend on proper ignition, combustion, airflow, venting, and safety-control operation. We diagnose problems involving burners, flame sensors, igniters, gas valves, heat exchangers, inducer motors, blower assemblies, control boards, and other applicable components.
02
Electric Furnaces
Electric furnaces use resistance-heating elements rather than combustion. We repair problems involving heating elements, sequencers, relays, electrical connections, motors, controls, and airflow components.
03
Air Handlers
Air handlers distribute conditioned air through the home. A blower failure, control problem, electrical issue, or airflow restriction can prevent the system from delivering adequate heat.
04
Heat Pumps
Heat pumps require specialized knowledge of refrigerant performance, reversing valves, coils, compressors, defrost controls, auxiliary heat, electrical components, and system airflow.

05
Packaged HVAC Systems
Packaged systems combine heating and cooling equipment in one cabinet. Our technicians diagnose applicable combustion, refrigeration, electrical, airflow, and control problems based on the equipment configuration.
06
Ductless Mini-Split Systems
Ductless mini-splits provide targeted heating and cooling without conventional ductwork. We diagnose problems involving indoor heads, outdoor units, refrigerant performance, electrical components, controls, drainage, and communication between system components.

What Tulsa Homeowners Are Saying About Mark Hill
Frequently Asked Questions About AC Repair
Before you schedule.
A few quick answers about your heating repair service questions and our coverage across the Tulsa metro.
Do you offer emergency heating repair in Tulsa?
Yes. Mark Hill Heating & Air is available 24/7 for urgent heating problems. Call (918) 258-8855 for the fastest available response.
What heating system brands do you repair?
We repair all major residential heating brands, including Trane, Carrier, Lennox, Goodman, Rheem, Ruud, York, Bryant, American Standard, and others.
Why is my furnace running but not producing warm air?
Possible causes include an ignition problem, a thermostat issue, restricted airflow, a failed heating component, a control problem, or an interruption in the fuel or electrical supply. A technician must inspect the system to identify the actual cause.
Why does my heating system keep turning on and off?
Frequent cycling may be connected to restricted airflow, thermostat problems, overheating, ignition difficulties, electrical components, system sizing, or other equipment conditions. Continuing to operate the system may place additional strain on its components.
What should I do if I smell gas or my carbon monoxide alarm sounds?
Leave the home immediately and contact the appropriate emergency or utility provider from a safe location. Do not operate electrical switches, use an open flame, or remain inside while attempting to locate the source.
Is it better to repair or replace my heating system?
That depends on the repair cost, the system’s condition, the equipment’s age, its breakdown history, efficiency, parts availability, and its ability to heat your home. Mark Hill will compare the options and explain whether the repair provides reasonable value.
Can you repair my system if Mark Hill did not install it?
Yes. We repair and maintain all major residential HVAC brands, regardless of who originally installed the equipment.
