Don't Ignore These Warning Signs

A heating system that's not working properly isn't just inconvenient — it can be a safety hazard, especially with gas-powered equipment. If you notice any of these warning signs, it's time to call for a professional inspection:

No heat or not enough heat — If your furnace is running but the air isn't warm, or it can't keep up with the thermostat setting, something is wrong. This could be a faulty igniter, bad gas valve, blower motor issue, or a problem with your thermostat.
Strange smells — A slight dusty smell when you first turn on your furnace for the season is normal. But a persistent burning smell, rotten egg odor (which indicates a gas leak), or musty smell should be investigated immediately.
Yellow or flickering pilot flame — A healthy gas furnace flame should be steady and blue. If the flame is yellow, orange, or flickering, it could indicate incomplete combustion, which can produce carbon monoxide — a colorless, odorless gas that is extremely dangerous.
Carbon monoxide detector alerts — If your CO detector goes off, take it seriously. Leave the house immediately, call 911, and then call us. Carbon monoxide leaks from cracked heat exchangers are one of the most serious furnace safety issues.
Unusual noises — Banging, popping, screeching, or rumbling sounds from your furnace usually indicate a mechanical problem — a loose blower wheel, failing bearings, a delayed ignition, or expanding ductwork.
Uneven heating — If some rooms are warm while others are cold, the issue could be with your ductwork, blower motor, or the system's overall capacity.
Frequent cycling — If your furnace turns on and off repeatedly in short bursts, it may be overheating due to a dirty filter, blocked vent, or malfunctioning flame sensor.

Safety Concerns with Gas Heating Systems

Gas furnaces are safe and reliable when properly maintained, but they do involve combustion, which means there are important safety considerations:

Carbon monoxide: A cracked heat exchanger can allow carbon monoxide to enter your home's air supply. Every home with a gas furnace should have working CO detectors on every level.
Gas leaks: If you smell rotten eggs or hear a hissing sound near your furnace or gas line, leave the house and call your gas company immediately.
Proper venting: Furnace exhaust must be properly vented to the outside. Blocked or disconnected flue pipes can cause dangerous gases to accumulate inside your home.

These are serious issues, but they're also preventable. Annual maintenance and prompt professional repairs keep your family safe. Never attempt to repair a gas furnace yourself — always call a licensed HVAC technician.

Our Heating Repair Process

When you call NexGen Comfort Services for a heating repair, we follow the same professional, transparent process every time:

Complete System Diagnostics

We don't just look at the obvious symptom — we inspect the entire heating system to find the root cause. This includes checking the heat exchanger for cracks, testing gas pressure, inspecting the ignition system, measuring temperature rise, checking safety controls, and testing the blower motor and electrical components. A thorough diagnosis means we fix the real problem, not just a symptom.

Clear Explanation and Upfront Pricing

Once we've identified the problem, we'll explain it to you in plain language — no technical jargon. We'll show you exactly what's wrong and give you a written quote before any work begins. If the repair doesn't make financial sense (for example, if the system is old and the repair is expensive), we'll tell you that too and discuss your replacement options.

Professional, Lasting Repairs

We use quality parts and proven repair techniques to ensure the fix lasts. Our technicians have over 25 years of experience working on all types of heating systems — gas furnaces, electric furnaces, heat pumps, and dual fuel systems.
