Expert Furnace Repair in Livonia MI — OnPoint HVAC


When your furnace stops working in the middle of a Michigan winter, every hour matters. OnPoint HVAC has been serving Livonia homeowners from our home base right here on Joy Road, which means when you call us for furnace repair in Livonia MI, we're not dispatching a crew from across the county — we're around the corner. Fast response isn't a marketing line for us. It's geography.


Livonia winters don't negotiate. When temperatures drop below freezing and your furnace isn't performing, you need answers — not guesswork. Every diagnostic visit from OnPoint HVAC is led by a licensed mechanical engineer, so your furnace problem is evaluated with the same technical rigor applied to commercial systems, brought to the residential level. We find the actual root cause, not just the easiest thing to replace.



As a family-owned company founded by mechanical engineer George Petrentzev, we built OnPoint HVAC specifically to raise the standard of residential HVAC work in Wayne County. We've seen too many Livonia homeowners handed inflated repair quotes or unnecessary equipment replacements. Our job is to give you an honest assessment and a repair that holds — backed by a warranty and a phone number you can actually reach. Whether you need emergency furnace repair in Livonia MI or you've noticed your system losing efficiency over time, we're the local furnace repair company built for this.

Common Furnace Problems We Fix

Furnaces fail in predictable ways. Here are the issues we diagnose and repair most frequently for Livonia homeowners:


No Heat / Furnace Not Turning On If your thermostat is calling for heat and nothing happens, the cause could range from a tripped circuit breaker to a failed igniter, a faulty limit switch, or a malfunctioning control board. We trace the signal path from thermostat to burner to find exactly where the breakdown is.


Short Cycling (Furnace Turns On and Off Repeatedly) A furnace that runs for 2–3 minutes and shuts off before your home reaches temperature is short-cycling. Common causes include an overheating heat exchanger, a clogged filter restricting airflow, or a miscalibrated flame sensor. Left unaddressed, short cycling dramatically shortens equipment life.


Unusual Noises — Banging, Squealing, or Rattling A healthy furnace runs quietly. Banging on startup often signals delayed ignition or expanding ductwork. Squealing points to a worn blower motor bearing. Rattling can indicate a loose panel or failing inducer motor. Each sound has a source — we find it.


Yellow or Flickering Burner Flame Your furnace burner flame should be steady and blue. A yellow or flickering flame is a warning sign of incomplete combustion, which can indicate a dirty burner, a failing igniter, or — critically — a carbon monoxide risk. This is not a "watch and wait" situation.


High Energy Bills / Loss of Efficiency If your gas bill is climbing but your home isn't getting warmer, your furnace is working harder than it should. Dirty heat exchangers, failing blower motors, and calibration issues all rob efficiency. We restore performance so your system heats your home, not your utility company.


Cracked Heat Exchanger A cracked heat exchanger is one of the most serious furnace safety issues a homeowner can face. It allows combustion gases — including carbon monoxide — to mix with the air circulating through your home. If we detect a crack during inspection, we will always be direct with you about the risk and your options.

Our Furnace Repair Process

Step 1 — Comprehensive Diagnostic Inspection Our technician performs a full system inspection: thermostat operation, electrical connections, ignition sequence, heat exchanger integrity, burner condition, blower motor performance, flue venting, and safety controls. Nothing is assumed.


Step 2 — Honest Assessment We explain what we found in plain language. No pressure tactics, no manufactured urgency. If the repair is straightforward, we tell you. If the system has deeper issues that affect its long-term reliability, we tell you that too — along with your options.


Step 3 — Repair or Replace Recommendation Based on system age, repair cost, and efficiency loss, we give you a clear recommendation. If repair is the right call, we proceed. If replacement makes more financial sense, we'll walk you through furnace installation in Livonia options without pressure. We also offer HVAC financing options to make either path manageable.


Step 4 — Completed Repair with Full System Test Once the repair is made, we run a complete operational test — startup sequence, heat output, thermostat response, safety shutoffs — before we close the service call. You know it works before we leave.

FREQUENTLY ASKED QUESTIONS

  • How much does furnace repair cost in Livonia MI?

    Furnace repair costs in Livonia typically range from $150 to $600 depending on the component that needs replacement and the complexity of the repair. We provide a firm quote before starting any work — no open-ended estimates. If cost is a concern, ask about our HVAC financing options.

  • How quickly can you come for furnace repair in Livonia?

Emergency furnace repair in Livonia MI is available for no-heat situations. Call us directly at (248) 331-8090 — our team will tell you exactly when we can arrive.

  • Should I repair or replace my furnace?

    If your furnace is under 15 years old and the repair cost is less than 50% of a new system's price, repair typically makes sense. If it's older and experiencing repeated failures, replacement often delivers better long-term value. We'll give you an honest comparison on-site — we never push replacement when a repair is the right answer. If replacement is the right move, we'll walk you through furnace installation in Livonia options.

  • Is my furnace safe to run while I wait for a repair?

    It depends on the issue. If your furnace is producing a yellow flame, you smell gas or burning odors, or your carbon monoxide detector has alarmed — turn the system off and call us immediately. If the issue is reduced heat output or unusual noise without safety indicators, running the system on a limited basis is generally lower-risk. When in doubt, shut it down and request a free estimate for emergency priority scheduling.
