Furnace Services in Berkley, MI
Reliable Furnace Heat Built for Long Oakland County Winters
Rated at 95 percent AFUE, a high-efficiency furnace turns about 95 cents of every fuel dollar into usable heat, compared with roughly 80 cents for the older standard-efficiency models still found in many metro Detroit basements. Charest Heating and Cooling provides furnace installation, replacement, and repair in Berkley, MI, as well as Huntington Woods, MI, Southfield, MI, and Shelby Township, MI. We install, repair, and upgrade gas furnaces with the right efficiency, staging, and blower features for your home.

Furnace Installation
A new furnace should fit your home's heating load, duct system, and venting options. We calculate sizing, install the equipment with proper gas and electrical connections, set up venting and drainage, and commission the furnace so it runs safely from the start.
Furnace Replacement
Furnaces over 15 years old, units with cracked heat exchangers, and systems needing expensive repairs are strong candidates for replacement. We remove the old equipment, prepare the space, and install a new furnace matched to your home and your existing air conditioner.
Furnace Repair
From failed ignitors and inducer motors to faulty pressure switches and control boards, furnaces have many components that can break. We diagnose the failure accurately, explain the repair and its cost, and restore safe, reliable heat as quickly as we can.
High-Efficiency Furnace Upgrades
Moving from an older 80 percent furnace to a high-efficiency condensing model can noticeably reduce gas usage. We handle the conversion, including new PVC venting and a condensate drain, so your upgraded furnace operates correctly and delivers the savings it promises.
Furnace Venting and Condensate Lines
Proper venting carries combustion gases safely outside, and condensing furnaces also produce water that must drain away. We install and repair vent pipes and condensate lines, check slope and terminations, and correct problems that cause shutdowns or water damage near the furnace.
Variable-Speed and Two-Stage Furnaces
Two-stage and modulating furnaces run at lower output most of the time, delivering steadier temperatures with fewer drafts and quieter operation. Paired with a variable-speed blower, they also improve filtration and air circulation, and we help you choose which configuration fits your home.

FAQ's
What does AFUE mean on a furnace?
AFUE, or Annual Fuel Utilization Efficiency, measures how much of the fuel a furnace burns becomes usable heat over a year. A higher percentage means less wasted fuel, with high-efficiency condensing furnaces typically rated at 95 percent or above.
How long does a gas furnace usually last?
Most gas furnaces last around 15 to 20 years with regular maintenance. Charest Heating and Cooling sees many Berkley, MI furnaces reach that range when owners change filters and schedule annual tune-ups, while neglected units often fail years earlier than expected.
What are the signs my furnace needs replacing?
Warning signs include age over 15 years, frequent repairs, rising gas bills, uneven heating, yellow burner flames, or a cracked heat exchanger. When several of these appear together, replacement is often more cost-effective than continuing to repair the old furnace.
What is the difference between single-stage, two-stage, and modulating furnaces?
Single-stage furnaces run at full output every time. Two-stage models add a lower setting for mild days, and modulating furnaces adjust output in small increments. More stages generally mean steadier temperatures, quieter operation, and better overall efficiency throughout winter.
What size furnace does my home need?
Furnace size depends on a heating load calculation that considers insulation, windows, air leakage, and square footage. Charest Heating and Cooling performs these calculations in Berkley, MI homes, because matching the old unit's size can repeat a decades-old sizing mistake.
Why is my furnace dripping water?
High-efficiency condensing furnaces produce water as part of normal operation, which drains through a condensate line. Dripping or pooling usually means that line is clogged, disconnected, or the condensate pump has failed, and it should be repaired quickly.
Can I replace my furnace without replacing my air conditioner?
Yes, as long as the new furnace is compatible with your existing air conditioner's indoor coil and airflow requirements. If your air conditioner is nearing the end of its life, replacing both together can improve efficiency and simplify future service.
What should I do if my furnace smells like gas?
Leave the house immediately, avoid switching lights or appliances on or off, and call your gas utility's emergency line from outside. Once the utility confirms the area is safe, a technician can inspect and repair the furnace and connections.
Why Choose Us for Furnace Services
Right-Sized Every Time
An oversized furnace cycles on and off constantly, while an undersized one runs nonstop on cold nights. We calculate your home's heating load before recommending equipment, so your new furnace delivers steady warmth without wasting fuel or wearing out prematurely.
Brands With Proven Track Records
We install furnaces from Goodman, Amana, Daikin, and Rheem, giving you choices across efficiency levels and budgets. Each brand is backed by manufacturer warranty coverage and a strong supply of replacement parts should you ever need service down the road.

Every furnace we install or repair gets its combustion checked before we consider the job complete. Verifying gas pressure, venting, and carbon monoxide levels helps make sure your furnace operates safely inside your home throughout the long heating season.
