Furnaces
MTB Mechanical installs, repairs, and maintains furnaces for homes throughout Matthews, NC and the greater Charlotte area, including Concord and Huntersville. When a furnace won’t ignite, runs constantly without warming the house, or is old enough that a breakdown feels inevitable, our certified technicians diagnose the cause and quote the repair, the tune-up, or the replacement by the job before any work begins.
Charlotte-area winters bring enough cold snaps each year that a furnace still matters in a region known for mild weather, and a furnace sized correctly for a Matthews-area home keeps operating costs down through the coldest week of the season instead of running constantly to keep up.

Furnace Inspection & Repair Services
Our certified technicians inspect and repair furnaces of every age and type, diagnosing the specific cause of a breakdown, whether it is an ignition problem, a blower issue, or a thermostat that has stopped communicating with the system. Most repairs are completed the same visit using parts carried on the truck, and the repair is quoted by the job before work begins.
Furnace Installations
Furnace installation starts with a load calculation that measures the home’s square footage, insulation, and layout, so the new furnace is sized to the home rather than guessed at. Our technicians walk through equipment options and efficiency ratings, and installation typically finishes in a single day.
Furnace Maintenance
Scheduled furnace maintenance checks burners, heat exchangers, filters, and electrical connections before they cause a mid-winter breakdown. A maintenance visit follows a documented checklist and ends with the furnace tested through a full heating cycle.

FAQs
How do I know if my furnace needs to be repaired or replaced?
A furnace under warranty or under 10 years old with a moderate repair cost is usually worth fixing. A furnace over 15 years old facing a repair that costs a third or more of a new furnace’s price is typically a better candidate for replacement, which a technician can quote alongside the repair.
How can I keep my furnace in good working condition?
Scheduling routine maintenance ensures optimal efficiency and catches potential issues early. Replace air filters regularly to improve airflow and prevent dust buildup, and keep the area around the furnace clean and free from obstructions. Adjust thermostat settings appropriately to prevent excessive strain on the system. Finally, be aware of unusual sounds or changes in heating performance and promptly seek professional assistance. By staying proactive and attentive, you can extend the lifespan and efficiency of your furnace.
How often should I clean or replace my furnace filter?
To maintain a properly functioning furnace, cleaning or replacing the furnace filter every one to three months is recommended. The frequency depends on factors like the type of filter used, the air quality in your home, and the presence of pets or allergies. Regular filter maintenance ensures efficient airflow, prevents dust accumulation, and improves indoor air quality. If the filter appears dirty or clogged, replace it promptly to avoid strain on the system, reduce energy consumption, and promote better air circulation throughout your home.
Why won't my furnace light?
A furnace that will not light is usually caused by an ignition failure, a clogged filter restricting airflow, or a safety switch shutting the system down. A technician tests each of these during the visit and repairs or replaces the failed part, most often the same day.
How long does furnace installation take?
Most residential furnace installations are completed in a single day. Jobs that involve ductwork changes or electrical upgrades can take longer, and the timeline is confirmed at the estimate.
How often should my furnace be serviced?
Most furnaces in the Charlotte area benefit from one maintenance visit a year, scheduled in the fall before the first cold snap, to check burners, filters, and electrical connections before they cause a breakdown.
What size furnace does my home need?
Sizing comes from a load calculation, which measures square footage, insulation, windows, and layout rather than matching the size of the old furnace. A furnace sized to the home runs efficiently and lasts longer, while an oversized or undersized furnace cycles too often and wears out early.
