Buffalo Furnace Repair

Cold air from a running furnace usually points to an ignition failure, a tripped limit switch, a dirty flame sensor, or an overheating issue that’s triggering a safety shutoff. It can also be something as simple as the thermostat being set to “fan only” instead of “heat.” A technician can pinpoint the exact cause and get it sorted quickly.

Short cycling is one of the more common furnace complaints we hear. It’s usually caused by restricted airflow from a clogged filter, an overheating system, a faulty flame sensor, or a thermostat that’s not reading temperatures correctly. Running in short cycles puts extra wear on components, so it’s worth addressing sooner rather than later.

It depends on the sound. A slight hum is normal. Banging, grinding, rattling, or squealing typically signals something mechanical that needs attention, and continuing to run the system can make the problem worse or create a safety issue. When in doubt, shut it down and give us a call.

Most repairs can be completed in a single visit. We come prepared with commonly needed parts, which means we can resolve the majority of issues the same day. More involved repairs involving specialty parts may require a follow-up, but we’ll let you know upfront if that’s the case.

Repair is usually the right call when the furnace is relatively newer, the issue is isolated, and the cost is reasonable. If your system is over 15 years old, requires repairs frequently, or is struggling to heat your home even when it’s running, replacement often makes more financial sense in the long run. We’ll give you an honest recommendation either way.

The single best thing you can do is schedule annual maintenance and change your filter every one to three months. Routine tune-ups let us catch developing issues before they become emergency calls, and clean filters keep the system from overworking itself.
