Signs It's Time to Replace Your AC
Replacement usually makes sense when two or more of these factors are true. If a repair is still the better buy, we’ll say so, and our AC repair page covers the fixes.
- It's more than 10 years old and needs a major repair (compressor, coil or fan motor)
- Its age times the repair cost tops $5,000 (the "$5,000 rule" some homeowners use)
- It runs on R-22 refrigerant, which is no longer produced, so every recharge costs more
- You've needed repairs more than one summer in a row
- The house feels sticky even when it's cool, a sign the system isn't removing humidity
What's Included in a Stoneman AC Installation
Every Stoneman installation includes:
- Free in-home estimate: we recommend a system size and give you options with upfront prices.
- Permit: we pull the county mechanical permit for the job.
- Removal and haul-away: we recover the old refrigerant, as federal rules require, and haul the old equipment away.
- Ductwork from our own shop: if your ducts need changes to fit the new system, our metal fabrication team builds them in-house.
- Installation and testing: we install the new system, set up the thermostat and test everything before we leave.
- Stoneman Concierge visit: after the install, our Concierge team comes back to go over the system with you, how it works and how to use the thermostat, so you aren’t left alone with a manual.
Which Type of Air Conditioner Fits Your Home?
For most Midlothian homes with ductwork, the choice is between a single-stage and a variable-speed central air conditioner. A single-stage system runs at full power until the house cools, then shuts off. A variable-speed system adjusts its output and runs longer at low speed. Two-stage systems sit in between. If your house stays damp even with the AC running, a whole-home dehumidifier can be added to either system. See indoor air quality.

How Much Does a New AC System Cost in Midlothian?
The price of a new air conditioner depends on five things, so we quote it after a free in-home estimate rather than from a chart: the system’s size, its efficiency rating, whether the indoor coil and air handler or furnace are replaced too, how much the ductwork needs, and any electrical work. You get the price up front, with a clear explanation of what’s included and no pressure to decide that day. Financing is available for qualified applicants on new installations and replacement systems.

AC Installation in Midlothian and Chesterfield County
Installing a new air conditioner in Chesterfield County requires a mechanical permit and a county inspection, even when the new unit replaces an old one of the same size. The county’s like-for-like exception applies to electric heat pumps, not central air. When you compare quotes, check that each one includes the permit. We’re based at 1636 Oak Lake Blvd E in Midlothian and install air conditioning across Midlothian, Chesterfield, Chester and Powhatan. Not sure if you’re in our area? Call (804) 744-6105.

AC Installation & Replacement FAQs
How long does an AC installation take?
A straightforward replacement of one system is usually done in a day. Two systems, new ductwork or electrical upgrades can add a day or more, and some equipment has to be ordered first. We’ll give you the timeline with your estimate.
What size AC do I need for my home?
The right size depends on the house, not on the unit you’re replacing. Square footage is a starting point, but insulation, windows, sun exposure, ductwork and the number of floors all change the answer. An oversized system shuts off before it removes humidity, leaving the house cool but clammy. An undersized one runs nonstop on 90-degree afternoons. We size the system during your free in-home estimate.
Can I replace just the outdoor unit?
Sometimes, but usually not. The outdoor unit and indoor coil are rated as a matched pair, and most new outdoor units use R-454B or R-32 refrigerant, which needs a compatible coil. If your current system runs on R-22, both sides have to be replaced. If it runs on R-410A, ask which refrigerant each side of the new system would use before you decide.
Are there rebates or tax credits for a new AC?
Not many right now. The federal tax credit for home cooling equipment ended for systems installed after December 31, 2025. Virginia’s Home Energy Rebates for income-qualified households haven’t launched yet, and when they do, they’ll cover heat pumps rather than central air conditioners. If a rebate matters to you, ask us to price a heat pump alongside the AC.
