Signs Your AC Needs Repair — Don't Wait Until It Fails Completely
Most air conditioner breakdowns don’t happen without warning. In fact, your system usually signals a problem long before it stops working entirely. Here are the most common signs it’s time to call for AC repair in Ann Arbor:
Warm air coming from the vents.
If your thermostat is set to 72°F but your rooms are sitting at 80°F, your system is working hard and getting nowhere. This is often a refrigerant issue, a failing compressor, or a dirty evaporator coil — all of which we can diagnose and resolve on the same visit.
Strange sounds — grinding, banging, or squealing.
Your AC should run quietly in the background. Unusual sounds almost always signal a mechanical problem that gets worse the longer you wait on it. Specifically, a banging sound usually means a loose internal component, while squealing often points to a failing belt or motor bearing.
Your energy bill spiked without a clear reason.
An AC system that's struggling uses significantly more electricity to deliver less cooling. As a result, if your DTE Energy bill jumped this summer without a change in your usage habits, your system's efficiency is worth having checked before the next billing cycle.
Water or ice forming around the unit.
Some condensation is normal, but pooling water or ice on the unit points to a drainage blockage, dirty coils, or a refrigerant problem. Left unaddressed, moisture issues can damage your flooring, walls, and the unit itself.
The system is short cycling.
If your AC is turning on and off every few minutes rather than running full cycles, it's under stress. Short-cycling causes accelerated wear and significantly shortens a system's lifespan — and it usually means your system is improperly sized or dealing with an airflow restriction.
Humidity isn't being controlled.
In addition to cooling your home, a properly functioning AC system removes humidity from the air. If your home feels sticky and muggy despite the AC running, something in the system isn't working as it should.
If you're experiencing any of these signs, call us before a $300 repair becomes a $4,000 replacement.

When Repair No Longer Makes Sense If your system is 12–15 years old, has needed repeated repairs, or the fix costs more than half of a replacement — a new installation is the smarter move. Modern high-efficiency systems deliver the same cooling for significantly less energy, lowering your DTE bills every summer.

FAQ
A good rule of thumb is the 50% rule: if the cost of the repair exceeds 50% of what a replacement system would cost, and your unit is more than 10 years old, replacement is usually the smarter financial decision. However, every situation is different, and we'll always give you an honest breakdown of both options so you can decide based on real numbers rather than a sales pitch.
Yes. Same-day service for AC repair is our standard — not an upsell. For emergency situations such as a complete system failure during a heat wave, we prioritize getting a technician to your door within 1–2 hours. Ypsilanti, Saline, Canton, Dexter, and Chelsea are all within 30 minutes of our Ann Arbor base.
We work on all major residential brands including Carrier, Trane, Lennox, Rheem, Goodman, York, American Standard, and more. If it's installed in a Washtenaw County home, our technicians are trained on it. We're not tied to any single brand, which means we diagnose issues objectively rather than steering you toward a particular manufacturer.
Yes, R-410A is still available for existing systems and will remain serviceable for years to come. However, it is no longer being manufactured in new systems as of 2025 due to environmental regulations. If your system uses R-410A, we can still service and recharge it. If you're considering a new installation, we'll discuss the newer R-454B refrigerant systems and what that transition means for long-term serviceability and costs.
We do. We offer flexible financing options so that a system replacement doesn't have to wait until you've saved the full amount. Ask us about current financing terms and available options when you request your free estimate — there's no obligation and no pressure.
A standard central AC installation in an Ann Arbor home typically takes between 4 and 8 hours. Ductless mini-split installations vary depending on the number of zones but are often completed in a single day. We arrive with all necessary equipment, handle the full removal and installation, test everything thoroughly, and clean up before we leave.
