Plenty of companies “do furnace repair.” Fewer actually diagnose correctly, fix the right component, and confirm the furnace is running safely at full cycle. In Haverhill winters, a quick reset can turn into frozen pipes, water damage, or a full equipment failure if the real problem is airflow, combustion, or controls.

Furnaces don’t fail randomly. They fail when a safety circuit trips, a component cannot perform under load, or airflow/combustion is outside safe limits. Cold snaps in Essex County push systems into long run times, which exposes weak parts fast. If your furnace is older or has not been serviced in a while, these issues show up as intermittent lockouts, short cycling, and “works sometimes” behavior.
“No heat” can be ignition, gas valve, control board, pressure switch, or flame sensing. “Cold air” can be burners not lighting, limit switch trips from overheating, or blower timing issues. “Short cycling” is often overheating, restricted airflow, failing inducer, or pressure switch tubing/condensate problems. The right fix depends on the root cause, not the symptom label.

We test the safety chain and performance under load so the fix is correct the first time.

Ignitors, flame sensing, gas delivery, pressure switches, and safe startup verification.

Restricted airflow causes overheating and shutdowns. We check what actually drives comfort.
Haverhill homes run everything from older oil equipment to high-efficiency condensing gas furnaces. Repair success depends on recognizing the system type, the safety circuit behavior, and the common failure patterns for that equipment.
Gas furnaces rely on ignition, flame verification, inducer draft, and safe combustion. Common repairs include ignitors, flame sensors, pressure switches, inducer motors, gas valves, and control boards. Many “no heat” calls are actually safety shutdowns caused by airflow restriction or draft/pressure issues.
If your furnace is high-efficiency (PVC venting, condensate drain), clogs and freezing condensate lines can trigger repeated lockouts in cold snaps.
Oil systems add burner-specific issues: nozzle wear, filter restriction, oil pump pressure, electrode alignment, and soot-related performance loss. Oil furnace “hard start” and rumble often point to ignition timing and burner setup, not just a “bad part.” Correct adjustment improves safety and efficiency.
We handle furnace repairs as part of the broader heating program in Haverhill. If you suspect your system is better served by a boiler, see Boiler Repair.
The goal is simple: restore safe heat and prevent repeat breakdowns. That requires real diagnostics, not guessing. We follow a consistent process so the outcome is reliable for homeowners in 01830, 01832, 01835 and nearby towns.
We look for fuel odors, venting issues, soot, condensate problems, and obvious hazards before restart attempts.
We test ignitor performance, flame sensor signal, burner operation, and confirm stable flame under load.
We confirm inducer operation, pressure switch behavior, tubing integrity, and vent/condensate conditions.
Restricted airflow overheats furnaces and trips limits. We check filters, duct restrictions, blower performance, and motor health.
After repair, we run the furnace through a full cycle to confirm safe startup, stable runtime, and consistent heat delivery.
Most repeat service calls come from incomplete diagnosis, not “bad luck.” If a furnace shuts down, it is usually protecting the home from unsafe combustion, overheating, or draft failure. Fixing the symptom without the cause creates a cycle of breakdowns. We solve the cause and verify operation.

You don’t need to “DIY a furnace,” but you can rule out a few safe items quickly. If anything seems unsafe, stop and call.
If the furnace repeatedly tries to start then stops, don’t keep cycling it. That can worsen failures and risks.
For urgent no-heat calls, use Emergency Heating Repair or call (978) 352-7900.
Furnace repair pricing depends on the failure type, system type, and the safety work required to restore proper operation. The goal is not “cheap,” it’s correct and safe. Below are the cost drivers we explain so homeowners in Haverhill can make informed decisions.
If the furnace is safe and the repair restores reliable operation, repairing usually makes sense. If the furnace is near end-of-life, has repeat safety shutdowns, or has a major failure that makes reliability questionable, we’ll explain replacement options and what affects installed cost.
For replacement details, see Furnace Installation Haverhill.

A furnace usually shuts off because a safety device is tripping, often from overheating due to restricted airflow, pressure switch/draft problems, flame sensing issues, or control faults. We test the full safety chain to find the root cause, then verify stable runtime so it doesn’t keep locking out.
Cold air typically means the burners are not lighting or not staying lit, or the furnace is overheating and shutting the burners down. Common causes include ignitor failure, dirty flame sensor, airflow restriction, or control timing issues. Proper diagnostics identify the cause and restore normal heat delivery.
Yes. Short cycling increases wear on ignition components, motors, and controls, and it often signals overheating, airflow restriction, or safety shutdown issues. Fixing short cycling early can prevent larger failures and restore comfort, especially during prolonged cold snaps in the Haverhill area.
Yes. High-efficiency furnaces have additional failure points like condensate drains, pressure switches, and venting issues that can trigger lockouts in cold weather. We diagnose those systems correctly, clear root causes, and verify safe combustion and stable operation before completing the job.
Yes. We service both gas and oil furnaces commonly found in Haverhill-area homes. Gas furnaces often fail from ignition, flame verification, or draft issues,
while oil systems can involve burner setup, nozzle/filter problems, and soot-related performance loss. We identify the system and repair it safely.
We base it on safety, reliability, repair history, and overall cost-to-own. If a repair is safe and restores reliable operation, we repair it. If the system is near end-of-life or has recurring critical failures, we explain replacement options and what affects installed cost so you can decide confidently.
Yes. After diagnostics, we explain what failed, what it takes to repair it, and what factors affect cost. Emergency timing, parts availability, and safety-related work can change price, but you’ll get clear expectations before we proceed with repairs.
Call immediately if your heat is out and the home is dropping toward freezing. Frozen plumbing damage can escalate quickly. Use emergency heating repair or call
(978) 352-7900, and if needed, take basic steps like opening sink cabinets to protect pipes while help is on the way.
