Expert Furnace Repair in Metro Detroit — OnPoint HVAC
Metro Detroit's Trusted Furnace Repair Pro's
Michigan winters are unforgiving. When temperatures drop below freezing and your furnace stops working, every hour without heat puts your family's comfort — and safety — at risk. At OnPoint HVAC, we respond fast across the Metro Detroit area with licensed, engineer led diagnostics and repairs that address the root cause of the problem, not just the symptom.
Founded by mechanical engineer George Petrentzev, OnPoint HVAC is not your average heating company. We bring a systems engineering perspective to every service call, meaning we assess your entire heating system before recommending a fix. Whether you're dealing with a furnace that won't turn on at 2 a.m. or a unit losing efficiency in the middle of January, our team is equipped to restore your heat quickly, safely, and correctly the first time. We proudly serve homeowners throughout HVAC services across Metro Detroit.
Common Furnace Problems We Fix
1. No Heat When your furnace runs but produces no heat, or fails to start entirely, the cause could range from a faulty ignitor and failed heat exchanger to a tripped circuit breaker or clogged air filter. We identify the exact failure point and restore your heat without unnecessary part replacements.
2. Short Cycling If your furnace turns on and off repeatedly in short intervals, it is short cycling. This strains components, drives up energy bills, and usually indicates an overheating issue, a malfunctioning flame sensor, or an improperly sized system. Left unaddressed, short cycling leads to premature system failure.
3. Unusual Noises Banging, rattling, squealing, or rumbling sounds are never normal. These noises often indicate loose or worn components including blower belts, motor bearings, or heat exchanger cracks that require immediate attention to prevent further damage.
4. Yellow Flame and Carbon Monoxide Risk A healthy gas furnace burns with a steady blue flame. A yellow or flickering flame is a serious warning sign that your furnace may be producing carbon monoxide (CO). This is a life safety issue. If you notice a yellow flame, discoloration around the furnace, or unexplained headaches in your home, call us immediately and evacuate if needed.
5. Loss of Efficiency If your heating bills are climbing but your home never seems to reach a comfortable temperature, your furnace is working harder than it should. Dirty heat exchangers, aging components, duct leaks, and improper airflow are common culprits. An engineer led inspection from OnPoint HVAC will pinpoint where efficiency is being lost.
Our Furnace Repair Process
Step 1: Diagnostic Inspection Our technician performs a thorough inspection of your furnace and heating system, including the heat exchanger, ignition system, blower assembly, flue, and controls. We use professional grade diagnostic tools to measure performance data, not just visual observations.
Step 2: Honest Assessment After the inspection, we explain exactly what we found in plain language. You'll understand what is causing the problem, what the risk is if it goes unaddressed, and what your options are. No pressure, no upselling, no surprises.
Step 3: Repair or Replace Recommendation Based on the age of your system, the cost of the repair, and the overall condition of the equipment, we provide an honest recommendation. If repair is the right call, we proceed. If replacement makes more financial sense, we'll tell you that too, and walk you through furnace installation options at your request.
Step 4: Full System Test Once the repair is complete, we run a full operational test of your furnace and heating system. We verify heat output, airflow, safety controls, and thermostat response before we leave your home.
