Central Air Conditioning Repair, Maintenance & Installation in Plano, TX

A North Texas summer puts a central air conditioner under more sustained load than almost anywhere else in the country. Trotter Air Services has kept cooling systems running across Plano and the Greater Dallas area since 1970, and every side of that work starts here: AC repair when a system stops keeping up, seasonal maintenance to stop that from happening, and installation and replacement when equipment reaches the end of its life.

Our technicians are NATE-certified and we are an Armstrong ProTeam dealer, which means factory-level training and parts access on the equipment we install. We service every major brand regardless of who put it in.

Central AC Repair

Warm air at the vents, a system that runs without cooling, or a unit that trips its breaker. We diagnose the real fault rather than replacing parts in sequence, covering refrigerant leaks, failed capacitors and blower motor problems.

autorenew

Central AC Maintenance

An annual tune-up before cooling season covers coil cleaning, refrigerant charge verification, electrical testing and condensate drain clearing. It is also what most manufacturer warranties require as documented professional service.

Central AC Installation

Sizing comes before equipment selection. We run a Manual J load calculation against your home rather than matching the tonnage of the unit coming out, and explain what a given SEER rating changes for a Texas cooling season.

Not Sure Which One You Need?

Most calls we take sort into four situations. If your system is blowing warm air or not running at all, start with AC repair. If it cools but the house never quite gets comfortable, that is usually airflow or charge, and a tune-up is the right first step. If repairs keep stacking up on aging equipment, ask us for the repair figure and the replacement figure together. And if you have no cooling in the middle of a Texas summer, our 24/7 emergency AC repair page covers how dispatch works.

North Texas Cooling

What a North Texas Summer Does to a Central AC

Equipment here runs long hours against high heat for months at a stretch. That changes which parts fail and how often.

Capacitors Give Out First

A run capacitor is the single most common failure we see on Plano cooling calls. The classic symptom is an outdoor unit that hums without the fan spinning. It is a straightforward repair, but letting the system keep trying to start puts the compressor at risk.

Refrigerant and Airflow

A slow refrigerant leak starves the system of capacity so gradually that most homeowners adjust to it rather than noticing. Restricted airflow from a dirty filter produces a similar complaint. Both are worth diagnosing before you conclude the equipment is finished.

plumbing

Condensate Drainage

Cooling produces water, and a blocked condensate line backs that water up where you do not want it. On systems installed in an attic, that is a problem worth preventing rather than discovering. Clearing the drain is part of every maintenance visit.

Sizing Decides Everything Else

A system with more capacity than the house needs satisfies the thermostat quickly and shuts off, which costs both comfort and equipment life. That is why we run a Manual J load calculation on replacements instead of matching whatever is out there now.

Frequently Asked Questions About Central Air Conditioning in Plano, TX

If the system is relatively young and the failed part is a common one such as a capacitor or contactor, repair is almost always the better value. Once a unit needs repeated repairs in the same season or has a failing compressor, replacement usually costs less across the life of the equipment. We give you both figures so the decision is yours rather than ours.

That symptom most often points to a failed run capacitor, which is among the most common cooling failures we see in Plano. Turn the system off at the thermostat until a technician can look at it, because letting it keep trying to start can damage the compressor.

Once a year, ideally in spring before the first sustained stretch of Texas heat. An annual visit covers coil cleaning, refrigerant charge verification, electrical testing and condensate drain clearing, and it satisfies the documented professional service requirement carried by most manufacturer warranties.

Yes. We are an Armstrong ProTeam dealer, which gives us factory-level training and parts access on that line, but our NATE-certified technicians repair and maintain every major brand regardless of who installed the equipment.
