AC Repair in Madison Heights, MI
North and east of the shop, up John R.
Cooling in Madison Heights splits along the same line the city does. The residential streets are postwar ranches with conventional split systems, and they behave predictably. The commercial corridors are a different animal: rooftop package units that sit exposed all year, take the full sun in July, and go untouched until the day the space stops cooling with customers in it. Those two jobs need different things from us, and it saves everyone time if we know which one we are coming to.
What we run into in Madison Heights cooling systems
- Rooftop package units on commercial buildings need clear service access and regular coil cleaning, and both get neglected until a July failure.
- The residential ranch stock cools predictably, so a house that will not hold temperature is usually a duct or charge problem.
- Buildings converted from one use to another often carry cooling equipment sized for the previous occupancy.
Getting someone out
For a no-cooling emergency, ring (248) 398-4015 rather than using the form. That line runs 24 hours. Scheduled work, including anything that can wait until the morning, runs Mon–Fri 8am–5pm out of the shop at 1880 E Nine Mile Rd, Ferndale, MI 48220.
It helps to know what you have before anyone arrives. The age of the unit, the brand on the front, and whether it is doing nothing at all or doing something wrong will usually narrow the problem down over the phone.

AC Repair in Madison Heights: questions we get
Do you service rooftop AC units on Madison Heights storefronts?
For small commercial buildings, yes, provided the unit is safely accessible. Rooftop package units fail differently from a residential split system: the usual culprits are coils that have not been cleaned in years, economizer dampers stuck in the wrong position, and condensate that has backed up. Let us know the building and the equipment when you call.
Why is my AC running but not cooling?
The three usual causes are a refrigerant charge that has dropped because of a leak, an evaporator coil that has frozen over, and a compressor that is not starting. A dirty filter sits behind more of these than people expect, because restricted airflow is what freezes a coil in the first place. Checking the filter costs nothing and is worth doing before you call.
There is ice on my air conditioner. What should I do?
Switch the cooling off at the thermostat but leave the fan set to on. That moves room-temperature air across the coil and thaws it without running the compressor against ice. Then check the filter. Running a frozen system risks sending liquid refrigerant back to the compressor, which turns a modest repair into an expensive one.
