AC Installation and System Change-Outs for Green Country Homes
A properly sized, correctly installed air conditioning system is the foundation of home comfort in Oklahoma. An oversized system cycles on and off too frequently, fails to control humidity, and wears out faster. An undersized system runs constantly, can’t keep up on the hottest days, and drives up your electricity bill. Getting the sizing right matters more than the brand name on the box.
Cool Down uses Manual-J load calculations to determine the exact cooling capacity your home needs based on square footage, insulation, window count, orientation, ceiling height, and local climate data. We don’t guess, and we don’t just match what was there before. If the previous system was the wrong size, we’ll tell you and size it correctly.

Signs You Need a New Air Conditioning System
System Is 15+ Years Old
The average central AC lasts 15 to 20 years. Past that window, efficiency drops, repair frequency increases, and parts become harder to source. Upgrading to a modern system can cut cooling costs by 30 to 40%.
Repair Costs Are Stacking Up
If you’ve spent more than half the cost of a new system on repairs in the past two years, replacement typically makes more sense financially.
System Still Uses R-22 Refrigerant
R-22 was phased out of production in 2020. Prices for remaining stock continue to climb. Replacing the system eliminates the R-22 dependency. See our retrofitting and efficiency upgrades page for more on the R-22 transition.
Home Never Feels Comfortable Despite the AC Running
If the system runs constantly but your house is still warm, humid, or has hot and cold spots, the equipment may be undersized, or the ductwork may have issues. A new, properly sized system with sealed ducts solves both problems.

AC Installation Options
- Standard Efficiency AC Replacement
Replace your aging system with a reliable, properly sized unit that meets or exceeds current federal efficiency minimums. A solid, cost-effective choice for homeowners focused on value.
- High-Efficiency AC Upgrade (16+ SEER2)
Step up to a high-efficiency unit that significantly reduces cooling costs. Upgrading from a 10 SEER system to a 16 SEER2 unit can cut cooling electricity use by roughly 40%. Financing makes the upfront cost manageable.
- Full System Change-Out (AC + Furnace + Coil)
When both the AC and furnace are aging, replacing both at once ensures compatibility, maximizes efficiency, and avoids a second installation disruption down the road. The $200-off special applies to full system change-outs.
- Ductless Mini-Split (No Ductwork Available)
For rooms or buildings without ductwork, a ductless mini-split provides efficient cooling (and heating) without the cost of installing new ducts. See our mini-split page.
Benefits of a New AC System
Lower Monthly Utility Bills
Modern systems use significantly less electricity than equipment from 10 to 15 years ago. The savings compound every month during Oklahoma’s long cooling season.
Better Humidity Control
A properly sized system runs longer, steadier cycles that remove more moisture from the air. Your home feels cooler at a higher thermostat setting, which saves additional energy.
Fewer Breakdowns
New equipment comes with a manufacturer’s warranty and our 1-year labor warranty. You won’t be calling for emergency repairs on equipment that’s brand new
Increased Home Value
A new, high-efficiency HVAC system is a selling point for any home. Buyers notice the age and condition of the system during inspections.
What AC
Installation Includes
Every installation starts with a free in-home estimate. We assess your current system, perform a Manual-J load calculation, and recommend equipment options with pricing. Once you approve the scope, we schedule installation, typically within a few days.
On installation day, we remove the old equipment, set the new condenser on a fresh pad, install the new evaporator coil, connect refrigerant lines, wire the thermostat, charge the system to manufacturer specs, and run a full performance test. Most standard change-outs are completed in one day. We clean up the work area, walk you through the new system and thermostat controls, and leave you with all warranty documentation.
Current special: $200 off any full system replacement, plus a complimentary smart or WiFi thermostat included at no charge. Financing is available | . See all current deals on our specials page.

This is the second time Rick has come out and fixed my unit from someone else messing it up! He’s very honest reliable and does a good job my AC is up and running the same day and only needed a relay switch to fix it! I was told I needed a whole new unit!
