AC Installation and Replacement in Dallas, TX
Need an AC replacement or a new AC unit? HVAC-R Finest handles air conditioner installation for homes and businesses across Dallas, DeSoto and nearby cities, from central AC and heat pumps to complete HVAC systems.
When It's Time for AC Replacement
It's 10 to 15 years old
Older systems lose efficiency and break down more often, especially after years of Texas summers.
Repairs keep adding up
Frequent or major repairs, such as a failed compressor, can cost more than they're worth on an old system.
It uses R-22 refrigerant
R-22 is no longer produced, so recharging an older system is expensive and gets harder every year.
Rising bills, uneven rooms
If the system runs constantly and some rooms never cool, it may be worn out or the wrong size for the home.
What a New AC Installation Includes
Assessment
We look at the home's size, layout, insulation and existing ductwork.
The right size
We recommend equipment sized for the home. A system that's too big or too small wastes energy and wears out sooner.
Free quote
You get a free, no-obligation quote for the replacement.
Installation
We remove the old equipment and install the new system, with its refrigerant lines, drain and electrical connections.
Start-up and checks
We test the system, set up the thermostat and show you how it works.

Two Rules That Affect Every New System
Since 2023, new air conditioners installed in Texas must meet a higher minimum efficiency, shown as a SEER2 rating. And new equipment now uses newer refrigerants such as R-454B in place of R-410A.
We'll explain what each one means for your options and your energy bills before you choose.

Frequently Asked Questions
Is the quote free?
Yes. We offer a free, no-obligation quote for replacements or ductwork.
How long does an AC installation take?
Replacing an existing system is typically a one-day job. Jobs that include new ductwork, or equipment in a hard-to-reach spot, take longer.
What is the difference between AC replacement and HVAC replacement?
AC replacement changes the outdoor unit and usually the indoor coil. HVAC replacement changes the heating equipment as well, such as the furnace or air handler.
What size AC do I need?
It depends on the home's size, insulation, windows and layout, not just the square footage. We size the system during the assessment.
Do I need to replace the indoor unit at the same time?
Often, yes. The indoor and outdoor units are designed to work as a matched set, and new refrigerants aren't compatible with older indoor coils.
