When your central air conditioner is failing, Flower City HVAC gets you cool again fast. We replace aging AC units with high-efficiency Carrier, Lennox, and Trane systems that are properly sized for your home and installed to manufacturer specs.
When to Replace vs. Repair Your AC
If your AC is over 12 years old and needs a major repair, replacement usually makes more financial sense. R-22 refrigerant (used in units made before 2010) is now scarce and expensive — another reason older units are often not worth repairing. We’ll give you an honest assessment.

The most common air conditioning mistake in this region is oversizing, and it is easy to see why: bigger sounds better, and a short cooling season makes it feel like insurance. In practice an oversized unit cools the air quickly, satisfies the thermostat, and shuts off before it has run long enough to pull moisture out — so the house is cold and damp rather than comfortable. It also short-cycles, which wears the compressor and drives up bills. A correctly sized system runs longer at lower output, holds a steadier temperature, and dehumidifies properly. Variable-capacity equipment does this better still. We size from a load calculation, not from what is currently on the pad.
Common Questions
My house cools fast but feels clammy. Why?
That is the signature of an oversized system. It reaches temperature before it has run long enough to dehumidify. A load calculation confirms it, and it is one of the most common findings we make in homes with recently replaced equipment.
Can I add AC if I have radiators and no ductwork?
Yes. Ductless mini-splits are the least invasive and least expensive route, and high-velocity systems run small tubing through existing cavities for a nearly invisible result at higher cost. Both are common in Rochester homes with hot-water heat.
Is a heat pump worth considering instead?
Increasingly yes. A cold-climate heat pump cools in summer and heats efficiently through most of the winter, with your existing furnace as backup for the deepest cold. If you are replacing air conditioning anyway, it is worth pricing both.
