Heating and Cooling Service in Southgate, Michigan
Furnace, AC and water heater service for Southgate homes, from our Monroe, Michigan office.

Our technicians travel about 26 miles from our Monroe, Michigan office to reach Southgate homes.
Southgate's streets were platted starting in the 1920s, but most of the building waited until just after World War II. That makes it a city of post-war houses, and their furnaces and ducts show it. We cover Southgate from our Monroe office at 2020 South Custer Road, about 26 miles by road.
Call us for furnace, air conditioning and water heater repair or maintenance at (734) 384-3910. We are open 7am to 7pm, 7 days a week, and you can book online too.

Built after the war
The 2020 to 2024 American Community Survey counts about 13,200 homes in Southgate, with a median build year of 1963. About 45 percent were built before 1960, many of them in the 1950s, and another 32 percent in the 1960s and 1970s. About seven in ten are single-family detached houses on city lots, and about a third of households rent.
Post-war houses were built with small, efficient duct systems for the furnaces of the day. Many have since added central air, finished a basement or put on an addition, all on the same ducts. The results we see most are rooms that run hot in summer, a furnace that cycles on and off quickly, and a return that is too small for the blower. Before you replace a furnace or air conditioner in a house like this, have the ducts checked too, so the new equipment is not fighting the old air path.
The water heater in a Southgate basement usually sits beside the furnace and often shares its flue. A tank that rumbles, leaves rust-colored water or runs out of hot water early is wearing out. We can flush it, repair it or replace it, and we check the venting either way, since a water heater that does not draft properly can spill exhaust into the basement.
If the heat or the gas is the problem
In Southgate about 83 percent of households heat with gas and nearly 14 percent with electricity. A small share use propane or other fuels.
- A gas smell is a get-out situation. Leave the house with everyone, then call 911 and DTE Gas from outside, as DTE asks. If someone feels ill or a carbon monoxide alarm is sounding, call 911 first. We can come out after DTE has made the house safe.
- Heat off and lights off? When the whole block has lost power, report it to DTE and watch the outage map. The furnace will need power before it can run again.

They came fast and with his tools and knowledge the Tec found the problem fast, he got a part and installed it, and the furnace kicked right on, I’m very and if I need service again I’ll call this company
Great price Friendly, professional and thorough. They performed routine maintenance on my system. Services: A/C system maintenance
Christian was great. Fair pricing, showed up same day and called to say he could come sooner as we were without AC. Diagnosed the problem, solved it and got us signed up for the annual maintenance plan for the AC/Furnace. Would highly recommend.
Southgate questions
- We added a room onto our Southgate house and it never cools down. Why?
- An addition is often tied into the old ducts with one small supply run and no return, so cool air goes in but has nowhere to come back. We can measure the airflow and tell you whether a return, a damper change or a separate system makes sense.
- Is a furnace from the 1990s worth repairing?
- Sometimes. It depends on what failed and the shape of the heat exchanger. We will tell you the repair price and what we saw, and if replacing makes more sense we say so plainly.
- Do you serve Southgate from Monroe?
- Yes, Southgate is about 26 miles from our Monroe office. The number to book is (734) 384-3910.
- Our water heater rumbles. What does that mean?
- Usually sediment on the bottom of the tank. A flush can help if the tank is not too far gone. If it is leaking or rusty at the base, replacement is the safer call, and we will tell you which one you are looking at.
