Comprehensive Heating Repair Services

A heating problem doesn’t always require replacement. Our team repairs residential heaters, heat pumps, and furnaces common throughout Gaithersburg.

Recommendations reflect the equipment’s condition and repair cost. We complete only the work you approve and explain when a repair is likely to be temporary or approaching the price of a new installation.

During a heating repair visit, you can expect:

An Expert Diagnosis from a licensed technician who inspects the equipment and identifies the cause of the problem.
A clear explanation of the repair options and Upfront Pricing before work begins.
Honest repair-versus-replacement guidance based on the equipment’s condition and repair cost.
Follow-Up Care through service reminders and maintenance recommendations.

When Furnace Replacement Makes More Sense

Furnaces typically last 15 to 20 years. Once a system moves beyond that range, recurring problems and declining efficiency make replacement a stronger option than another short-term repair.

Age isn’t the only consideration. A repair that would provide only a temporary fix or approach the cost of a new system is a reason to compare home heater replacement options. Furnaces manufactured before 1992 can have Annual Fuel Utilization Efficiency ratings as low as 56% to 70%, far below current minimum efficiency standards.

Heating Installation & Replacement Support

Furnace replacement begins with an in-home consultation and help selecting equipment suited to your existing setup and replacement priorities. We complete the heating installation and perform a final check before the technician leaves.

A new heating and cooling system lease starts as low as $155 per month with no money down. The lease includes installation, preventative maintenance, repairs with parts and labor, and air filters.

Active duty, retired, and veteran military personnel receive a 10% discount on any product or service.

Ongoing Heater Service & Maintenance

Scheduled maintenance can uncover wear, safety concerns, and performance problems before winter use or an emergency repair visit.

Each visit includes careful inspection, cleaning, and safety checks for the equipment common in Gaithersburg homes. We also answer your questions and offer advice based on what the technician finds.

Available preventative maintenance options include:

A $99 HVAC Precision Tune-Up, excluding oil furnaces.
Maintenance+ membership with an automatic 15% discount on services and repairs.
Preventative maintenance included with the HVAC system lease.

Routine maintenance gives a technician an opportunity to assess equipment condition before winter use or an emergency repair visit. Inspection findings also give you a clearer basis for planning future service.

Understanding AFUE Furnace Efficiency Ratings

Annual Fuel Utilization Efficiency, or AFUE, measures how much of a furnace’s fuel becomes usable heat over a typical year. AFUE ratings are tested under procedures established by the U.S. Department of Energy.

As of 2026, the federal minimum AFUE for a non-weatherized gas furnace is 80%. ENERGY STAR certified gas furnaces in Maryland reach an AFUE rating of 95% or higher under the applicable high-efficiency benchmark. Comparing these ratings helps homeowners understand the efficiency difference between an older furnace and a replacement system.

Montgomery County Heating Replacement Permits

Montgomery County requires a residential mechanical permit to install, alter, repair, remove, convert, or replace a mechanical heating, ventilation, and air-conditioning system. These requirements apply to heating-system replacement work in Gaithersburg.

A gas furnace installation or replacement requires inspections by the Montgomery County Department of Permitting Services and WSSC Water. An all-electric heat pump installation or replacement requires an inspection by the Department of Permitting Services.

FAQs We’ve Got Answers to Your Heating Services Questions

We’ll do an in-home consultation, work with you to find the best heating system for your needs, perform the installation and also check that the system is working before leaving.
It’s common for your heating and cooling equipment to make a little noise. However, hearing odd or loud noises could mean there’s an electrical problem or trouble with the blower fan or capacitor. If not fixed, there can be serious (or expensive) consequences later on.
A popping disturbance is a common sign of an insufficient duct design. This occurs when there’s more airflow than your ductwork can manage.
Troubles with your ductwork can lead to other ventilation and air quality troubles, such as:
- Significant noise
- Greater energy needs
- Early system malfunction
- Irregular heating and cooling
- Broken AC compressor in the summer
- Too hot furnace or heat pump in the winter
- Mold growth inside ducts
Call a qualified company in the U.S like CroppMetcalfe Gaithersburg to examine your home’s ventilation system. We can offer suggestions for duct repair or installation.
