Houses on the water
Wayne County describes Gibraltar as a city cut by more than five miles of canals, wetlands and streams. The 2020 to 2024 American Community Survey counts about 2,400 homes, with a median build year of 1975. The mix is wide: about 35 percent are older than 1960, about 22 percent date from the 1960s and 1970s, and about 27 percent were built in 2000 or later. Around seven in ten are detached single-family houses, and fewer than one household in five rents.
On a waterfront lot, the A/C condenser often sits where the wind carries leaves, grass and debris into it. A dirty coil makes the unit work harder and fail sooner, so a yearly cleaning pays off here. Inside, if your furnace is in a crawlspace or a tight closet, tell us when you call, and we will bring what we need.
Natural gas, safety and outages
Gibraltar leans on gas more than its neighbors: about 93 percent of households heat with natural gas and about 6 percent with electricity.
- If there is a gas smell, get out of the house with everyone. Then, from outside and away from the smell, call 911 and DTE Gas, as DTE asks. Call 911 immediately if anyone feels sick or a carbon monoxide alarm sounds. Once DTE says it is safe, we will find the cause.
- If the power is out, look at DTE's outage map when the neighbors are dark too. The furnace cannot run without power. When it comes back and the heat does not, check the thermostat and the furnace switch, then call.

Maintenance near the water
In the spring, have the A/C tune-up done before the first hot spell, including a coil cleaning. Through the summer, hose off the outdoor unit gently and keep plants a couple of feet back from it. In the fall, the furnace tune-up checks the burners, venting and carbon monoxide. A VIP plan covers both visits each year, and we call you to book.

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.
Gibraltar homeowners' questions
- Gibraltar uses the Rockwood ZIP. Do you still come out?
- Yes. Most of Gibraltar is in 48173 and a sliver in 48183, and neither one changes anything for us. Our Monroe office is about 20 miles away.
- Our air conditioner on a canal lot seems to wear out fast. Why?
- Outdoor units close to the water and to trees pick up more debris, and a clogged coil runs hotter and harder. A yearly cleaning and a little space around the unit help. If yours is older, we can tell you if a repair is worth it.
- Do you work on the islands?
- Yes, on all four: Hall, Edmund, Main and Horse. Phone (734) 384-3910 or book online and give us the street address.
- Our house feels damp in summer even with the AC on. What helps?
- A dehumidifier can help, especially in a basement that smells musty. An air conditioner that is too big for the house can also leave it clammy, because it shuts off before it has pulled the moisture out. We can check the AC and talk through both.
