Furnace Repair & Replacement in Fenton, MI
In February, a furnace in Linden kept shutting itself off with a red blinking code. The cause wasn't a broken part at all: the return air was too small and a lot of the supply registers were closed, so the furnace was overheating and tripping its safety. We opened up the airflow and checked the furnace's numbers before leaving.
That's the kind of thing we look for first. Dion's Complete repairs and replaces gas furnaces in Fenton, Fenton Township and Linden, 24 hours a day. Call (810) 673-7228 or book online.

Furnace problems we see around Fenton
- Overheating and shutting off. Usually airflow: a small return, closed registers or a clogged filter. The furnace trips its high-limit switch and blinks a code.
- A gas valve that sticks or seizes. The furnace hiccups, then quits. Older furnaces around Linden have done exactly this.
- Running nonstop with a flashing light. Common on furnaces that went years without maintenance, especially in homes that just sold.
- No power at all. Before you call, check the thermostat batteries and the furnace's fuse or breaker. We've had a Fenton no-heat, no-AC call that came down to dead batteries and a blown 3-amp fuse.
- Warm air from the AC and an iced-up coil in summer. The furnace and AC share a blower and coil, so one problem can take down both.
Recent furnace jobs in Fenton and Linden
Overheating from airflow, River Bend Dr, Linden (February)
Red blinking lights and a furnace that kept shutting down. Andrew found an undersized return and a lot of closed supply registers. He opened the supplies back up, then checked the numbers: static pressure at 0.36 inches, a temperature rise of 70 to 75 degrees, and flue carbon monoxide under 100 ppm.
A sticking gas valve, then a new furnace, W Ray Rd, Linden (January to February)
In January, an old gas furnace was hiccupping and then going out. Nothing was failing during the visit, so Andrew tested it, checked for carbon monoxide and the electrical, and told the homeowner the gas valve was likely sticking. About a week later it seized for good, on a Sunday. He replaced the valve that day, redid the gas piping and set the gas pressure. Five days after that, the homeowner had us replace the furnace.
Running nonstop with a green flashing light, Hidden Hollow, Fenton (April)
New owners moved in and the furnace wouldn't stop running. It had clearly been neglected for a long time. They went with a new standard-efficiency furnace, installed by Kirk.
A full heating and cooling replacement, Water View Ln, Fenton (August)
The AC was blowing warm air and the coil was iced over. The homeowner replaced the whole system, furnace and AC together, installed by Jeremy. When the new equipment's duct transition didn't fit the way it should, Jeremy came back, built a new transition, trimmed it to size and sealed the seams. See AC repair in Fenton.

Furnace replacement in Fenton
We install 80% and 95% efficiency gas furnaces. A 95% furnace wrings more heat out of the gas and vents through PVC pipe. An 80% furnace costs less upfront and uses your existing vent. We'll look at your house, your ductwork and how long you plan to stay, and price both.
Every new furnace and air conditioner comes with a 10-year parts and labor warranty. If your AC is near the end too, replacing them together means one install and matched equipment.

What customers say
"I called and get same day service for a furnace issue. I couldn't be happier with our technician Jake and his great customer service. We have a bit of an odd situation but Jake took his time to do thorough inspections and provided me with estimates for multiple systems and also offered some recommendations to go about fixing some other odds and ends around our home. We will be moving forward with an estimate for a tankless water heater and a new HVAC system in the future. I highly recommend their services!" — Danni, Google review
"The Dion's team successfully installed a new air conditioning unit and furnace in my rental property. I was thoroughly satisfied with the service provided by their team and subsequently decided to have the hot water heater replaced. I wholeheartedly recommend Dion's to any friends or family members who may require their services. I intend to utilize their expertise for any future endeavors. Thomas and Andrew demonstrated exceptional knowledge and assistance throughout the process. The professional appearance of their matching uniforms conveyed a strong sense of teamwork and professionalism." — Benjamin B., Google review
Fenton furnace FAQ
Why does my furnace keep shutting off with a blinking light?
Often it's overheating. A return air that's too small, closed registers or a dirty filter can trip the high-limit switch. The blinking code tells us where to start, and we measure airflow and temperature rise to confirm it.
Is there anything I should check before I call?
Yes: the thermostat batteries and settings, the furnace filter, the power switch near the furnace, and the breaker. We've had Fenton calls where dead thermostat batteries and a blown fuse were the whole problem.
How long does a furnace last?
Often 15 to 20 years with regular maintenance. A furnace that's been neglected can wear out much sooner, which is common in homes that just changed hands.
Is a high-efficiency furnace worth it in Michigan?
Often, because Michigan winters are long and the furnace runs a lot. A 95% furnace costs more upfront and needs PVC venting, while an 80% unit uses the existing chimney or vent. We'll price both so you can compare.
Do you do emergency furnace repair in Fenton?
Yes. We answer 24/7. If your furnace quits on a cold night, call (810) 673-7228.
