• Safety concerns such as carbon monoxide from combustion problems

Everest Air Heating and Cooling understands local conditions and common home configurations in Blount County. That local knowledge lets technicians prioritize safety and efficiency, and recommend repairs that address root causes rather than temporary fixes.

Heating systems we repair

We work on the primary types of heating equipment used in Maryville homes:

• Furnaces (gas, electric, and oil-fed units)
• Heat pumps (air-source and hybrid systems used for heating and cooling)
• Ductless Mini Split systems (single- and multi-zone inverter-driven units)
• Packaged heating systems and dual fuel setups
• Components that support heating: thermostats, ductwork, and air handlers

Technicians come prepared for common brands and models found locally, and they apply industry-standard diagnostic methods to quickly identify failures and recommend the most reliable repair options.

Symptom-based diagnostics: What we check first

A symptom-driven approach provides fast clarity. Below are common symptoms Maryville homeowners report, what they typically indicate, and the initial checks a technician will perform.

• Heating system will not turn on
  
  • Likely causes: tripped breaker or blown fuse, thermostat issue, safety switch, or control board failure.
  • Technician checks: electrical supply, thermostat batteries and wiring, service switches, safety interlocks, and control board diagnostics.
• System runs but no heat or very little heat
  
  • Likely causes: pilot or ignition failure (gas furnaces), failed heating element (electric furnaces), refrigerant issues or compressor failure (heat pumps), restrictive airflow.
  • Technician checks: ignition sequence, flame sensor, heat exchanger, heat strips or elements, refrigerant pressure, and airflow through filters and ducts.
• Short cycling or frequent on-off cycles
  
  • Likely causes: clogged air filter, oversized thermostat setting, faulty thermostat, pressure switch problems, or failing control board.
  • Technician checks: filter condition, thermostat calibration, safety switches, and system run capacitors and relays.
• Unusual noises during operation
  
  • Likely causes: failing blower motor, loose panels, fan blade issues, ignition or combustion noise, or refrigerant-related clunks.
  • Technician checks: blower motor bearings, mounts, belts (if present), fan motors, and combustion chamber inspection.
• Uneven heating or cold zones
  
  • Likely causes: duct leaks, closed or blocked registers, zoning control issues, or failing multi-zone ductless heads.
  • Technician checks: ductwork integrity, damper operation, air balancing, and Mini Split indoor unit diagnostics.
• Heat pump is icing up or not defrosting
  
  • Likely causes: failed defrost control, low refrigerant, faulty reversing valve, or dirty coils.
  • Technician checks: defrost control circuits, refrigerant charge, coil cleanliness, and reversing valve function.
• Odors or suspected combustion problems
  
  • Likely causes: cracked heat exchanger, fuel leaks, or buildup of dust and debris.
  • Technician checks: visual heat exchanger inspection, combustion safety testing, and appropriate carbon monoxide checks.

These diagnostic steps are performed with safety as the top priority and are designed to isolate the cause so repairs target the source rather than symptoms alone.
