John Calhoun Electric & HVAC provides heating maintenance and tune-ups for homeowners throughout Roanoke, VA and nearby communities. We service heat pumps, furnaces, electric heat, dual-fuel systems, thermostats, blowers, and the controls that keep everything working together.
Regular maintenance gives us a chance to check the system before you are depending on it every day.
Why maintenance matters
A dirty filter chokes airflow. A blower motor starts to labor. A thermostat gets set up wrong. A control board shows trouble before it quits altogether.
Our work history includes heating calls involving airflow restrictions, blower motor problems, thermostat issues, control problems, defrost problems, and systems running hotter than they should.
A tune-up gives us a chance to look for those problems early.
That is how you avoid a no-heat call in January.
A thorough system check
Our maintenance process is based on the same things our technicians check during real heating repair calls.
The thermostat controls when the system starts, stops, and changes modes.
Our technicians have repaired heating problems tied to thermostat setup, wiring, programming, and control issues.
During maintenance, we check that the thermostat is calling for heat correctly and that the system responds the way it should.
Good airflow is important for both comfort and equipment safety.
Our service records include a gas furnace that was running too hot because airflow was restricted by a dirty screen before the heat exchanger. The technician cleaned and serviced the furnace and checked the high-limit control and return airflow.
We check the filter and look for anything choking airflow.
The blower moves heated air through the home.
Our technicians have diagnosed blower motors that would not start, motors with bad windings, and loose electrical connections at the motor.
During a tune-up, we check blower operation and listen for signs of poor performance or unusual noise.
Heating systems depend on electrical parts even when the main heat source is gas.
We inspect electrical connections and controls and look for signs of loose wiring, worn parts, or other problems.
Our work history includes heating issues tied to motors, thermostats, relays, control boards, and other electrical components.
If your home uses a heat pump, we check how the system is operating in heating mode.
Our technicians have worked on heat pumps with low refrigerant, defrost problems, reversing valve concerns, control issues, and systems entering lockout.
A maintenance visit gives us a chance to check for signs that the system is not heating the way it should.
Many heat pumps use electric backup heat when more heating is needed.
Our technicians work with heat strips, air handlers, and dual-fuel systems.
If you have backup heat, we make sure it runs and that the controls hand off between heat sources correctly.
Equipment covered by our furnace services uses safety controls to protect the equipment when something is not operating correctly.
We look for overheating, weak airflow, and controls shutting the furnace down.
Our service history includes systems where high-temperature and airflow problems needed to be checked together.
At the end of the visit, we run the system and make sure it is heating properly.
That means supply temperatures, thermostat response, blower operation, backup heat, and controls.
The goal is to make sure the system starts, runs, and shuts down the way it should.
Typical maintenance visit
A heating maintenance visit covers:
The exact steps depend on the type of system in your home and what we find during the visit.
Maintenance timing
For most Roanoke homeowners, heating equipment should be checked once a year before heating season.
Fall is usually the best time. That gives you a chance to find problems before the system is working hard every day.
A heat pump does both jobs, so it earns two visits a year. One before cooling season, one before heating season.
Older systems or equipment with a history of repairs may also need more frequent attention. If a major failure is found, we can explain whether heating installation and replacement should be considered.
Heating maintenance for Roanoke homeowners
Maintenance will not stop every heating problem. It does find most of them while they are still small.
John Calhoun Electric & HVAC provides heating tune-ups and maintenance throughout the Roanoke area. Our technicians use the same practical checks during maintenance that they rely on when diagnosing real heating problems.
If you want to make sure your furnace, heat pump, or other heating system is ready for colder weather, contact John Calhoun Electric & HVAC to schedule a heating maintenance visit.
