Checking several boxes? Let’s talk about your options — no obligation.
Repair or Replace? Let's Do the Math
Repair Makes Sense If
- Your system is under 10 years old
- It's a minor or isolated issue
- The repair cost is modest
- Your energy bills have been steady
Replace Makes Sense If
- Your system is 10–15+ years old
- Repairs are adding up or frequent
- Your energy bills keep climbing
- It uses outdated R-22 refrigerant
The 50% Rule
If a repair would cost more than half the price of a new system, replacement usually makes more sense.
Choosing Your New AC
A new AC is a long-term investment. Here’s what matters — and what we’ll walk you through.
Efficiency (SEER2)
Higher SEER2 ratings mean lower energy bills. We'll show you the options and the real-world savings to expect.
Features & Comfort
Variable-speed compressors, smart thermostat compatibility, and humidity control all affect how your home feels.
Brand & Quality
As a GE Authorized Pro, we install equipment we trust — and we service every major brand if you prefer another.
Warranty
We install systems backed by strong manufacturer warranties, and we stand behind our work on top of that.
Proper Sizing Matters More Than Brand
The most common mistake in AC replacement? Installing the same size as the old unit without checking if it’s actually right for your home.
We do a proper load calculation — measuring your home’s square footage, insulation, windows, and layout — to size your new system exactly right. Not too big, not too small.
Manual J load calculation — done right, every time.
Too Big (Oversized)
- Short-cycles on and off constantly
- Poor dehumidification — clammy air
- More wear and shorter lifespan
Too Small (Undersized)
- Runs constantly, can't keep up
- High energy bills from overworking
- Shorter equipment lifespan
Sized Right
- Even, consistent cooling throughout your home
- Proper humidity control and comfort
- Lower bills and longer system life

“When our 14-year-old AC finally gave out, Gem City walked us through replacement options without any pressure. They helped us pick a system that fit our budget, and the installation was clean and fast. Our new GE unit is noticeably quieter and our bills dropped.”
Robert P.
Centerville, OH
“I appreciated that they actually did a load calculation instead of just swapping in the same size unit. The new system cools the whole house evenly — even the upstairs bedroom that was always hot. Worth every penny.”
Linda H.

“From the free estimate to the final walk-through, the whole replacement process was smooth. They hauled away the old unit, cleaned up everything, and showed us how the new thermostat works. True professionals.”

How much does a new AC cost?
It depends on the size of your home, the system you choose, and the efficiency level. That’s exactly why we offer free in-home estimates — we’ll assess your home and give you upfront pricing with no obligation.
How long does an AC replacement take?
Most replacements are completed in a single day. Larger or more complex jobs may take longer, but we’ll tell you the timeline upfront so you know what to expect.
How do I know what size AC I need?
We do a proper load calculation (Manual J) that accounts for your home’s square footage, insulation, windows, and layout. We never just swap in the same size as the old unit — we size it right for your home.

A well-installed, well-maintained system typically lasts 12–15 years or more. Regular maintenance is the biggest factor in getting the full life out of your investment.

Yes. We offer flexible financing options to spread the cost of a new system into manageable monthly payments. Ask us and we’ll walk you through what’s available.
