Heating & Furnace Repair Service in Maryland
No-heat calls answered around the clock in winter, with combustion safety testing on every visit — including a carbon monoxide check.
A furnace that will not light on a 20-degree Maryland morning is an emergency, and we treat it as one. We answer no-heat calls 24 hours a day through heating season and carry the parts that account for most failures: igniters, flame sensors, pressure switches, inducer motors, gas valves, capacitors and control boards for the equipment families common in this market.
Every no-heat visit includes a combustion safety check, not just a repair. We test for carbon monoxide, verify draft and inspect the heat exchanger, because a furnace that is running is not automatically a furnace that is safe. If we find a cracked heat exchanger we will red-tag it and explain exactly what we saw and why — and we will show you.
Where we workScope
What the job actually includes
- Full ignition sequence diagnosis: thermostat call, inducer, pressure switch, igniter, gas valve, flame sense
- Carbon monoxide test in the flue and in the living space
- Heat exchanger inspection, with camera documentation when a crack is suspected
- Gas pressure verification at the manifold and inlet
- Temperature rise measured against the data plate range
- Safety switch, limit and rollout testing
- Stocked common failure parts for same-visit repair on most calls
Maryland specifics
Code, permits and rebates
Maryland law requires carbon monoxide alarms in most residential dwellings with fuel-burning appliances or attached garages, and any furnace repair visit is a reasonable moment to verify yours are present and in date. Repairs themselves do not require a Montgomery County permit, but replacement of the appliance does. If we find a cracked heat exchanger or unsafe draft condition, we are obligated to shut the appliance down and notify you in writing — we will also help you get temporary heat in place the same day.
Licensing
MD HVACR Contractor License #01-XXXXX. All refrigerant handling is performed by EPA Section 608 certified technicians, and equipment replacement is permitted and inspected through the county.
Process
How we run a furnace repair job
-
Phone triage
Thermostat batteries, filter condition, the furnace switch that looks like a light switch, a tripped breaker and a condensate float switch tripped by a clogged drain account for a meaningful share of winter no-heat calls. We check those with you before dispatching.
-
Sequence-of-operation diagnosis
We watch the furnace attempt to start and identify precisely where the sequence stops. A flashing LED code on the control board narrows it further. This is faster and far more accurate than swapping parts until the symptom goes away.
-
Combustion safety check
CO in the flue, draft pressure, flame appearance and heat exchanger condition. This happens on every visit whether or not it relates to your complaint.
-
Repair and verification
Part replaced, full cycle run start to finish, temperature rise confirmed inside spec, and readings written on the invoice.
Pricing
What moves the price
We do not publish a single number, because a number without your house attached to it is marketing rather than information. These are the variables that actually decide what a job costs, and we itemise all of them in writing before any work begins.
The failed component
Flame sensors and igniters are inexpensive and common. Inducer motors, gas valves and control boards sit in the middle. Heat exchangers on out-of-warranty equipment usually cost more than the furnace is worth.
Parts availability
Control boards and gas valves for common furnace lines are stocked locally. Proprietary boards for discontinued or premium European equipment sometimes take days, and we will tell you that at diagnosis rather than after.
Emergency timing
Overtime rates apply nights, weekends and holidays. Both rates are quoted before we dispatch.
