Whether you call it AC replacement, air conditioner replacement or new AC installation, the work is identical and so is the quote you approve first.
What an AC replacement actually involves
We start by measuring the home, not by matching the sticker on the old unit. Cooling load depends on square footage, window area, insulation, ductwork and how the house was built, and a century-old home behaves nothing like a 1970s subdivision ranch. Once we agree on equipment, we recover the old refrigerant, pull the condenser and coil, correct the line set and drain, set the new equipment level, and commission the system while we watch it run. We clean up and leave the basement or crawlspace the way we found it.
What we check and install
Beyond the outdoor unit, we look at the indoor coil, the blower, the plenum connections, the condensate drain and pan, the disconnect and wiring, and the thermostat. Ductwork gets a look too, because a new AC pushed through leaking or undersized returns will never cool the back bedrooms. We install a matched indoor and outdoor pair, new refrigerant lines or a flushed line set, a proper pad, and a float switch on the drain so a clog does not soak your ceiling.
How we decide replacement is the right call
We tell you when a repair still makes sense. A capacitor, a contactor, a fan motor or a bad thermostat is often worth fixing on a system with years left. Replacement comes up when the compressor is dead, when a leak is inside the coil, when the refrigerant is obsolete, or when the unit is old enough that one repair leads straight into the next. We show you what we found and give you both options in writing so the choice is yours.

Do I have to replace the indoor coil too?
Usually yes. The outdoor unit and indoor coil are designed to work as a matched pair, and pairing new outdoor equipment with an old coil hurts cooling and can shorten the life of the new system.
How long does an AC replacement take?
Most straightforward changeouts are a single day. Jobs that need duct corrections, electrical work, a new line set or difficult attic and crawlspace access can run into a second day, and we tell you that upfront.
Can I replace only the AC and keep my furnace?
Often yes, if the furnace is sound and the blower can move the airflow the new AC needs. We check the blower and the cabinet first, since a mismatched pairing can leave rooms uneven.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That short conversation tells us whether you need a visit today or tomorrow morning.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and ducts, and the equipment itself. We find the actual cause instead of swapping parts and hoping the noise goes away.
- Step 3
You decide before we work
We explain what failed, what the repair involves, and what we would do if it were our own house. Nothing gets replaced until you say go. Then we test the system before leaving.

Why homeowners call us
- Old houses and new onesWe are used to century-old homes with retrofitted ductwork and 1970s subdivisions with original returns. Tight crawl spaces, low basement headroom and odd attic runs are normal parts of the day for us, not surprises that stall the job.
- Built for the swingsHumid summers push AC systems hard and January freezes expose weak igniters and cracked flues. We repair for both extremes across the region, so the fix holds when the weather turns instead of failing the first hard week.
- Air conditioning and heating bothAir conditioner repair in July, heating repair in January, and the IAQ and airflow problems that hide in between. One crew that knows how your cooling and heating share the same blower and the same duct system.
- Plain talk, no pressureWe tell you when a repair makes sense and when replacement is the honest answer. No scare tactics about your BTU load, no upsell scripts. You get the condition of the system and a clear next step.
- All major brands, gas & electricEvery major HVAC brand, gas and electric, handled by an independent crew.
- Straight answersIf a system is not worth repairing, we say so, often right on the phone.
