AC Repair in Lavon, TX

When your air conditioner breaks down in the middle of a Texas summer, every hour without cooling matters. Precision TX Heat & Air is a family-owned AC repair company based in Lavon, TX, serving homeowners and businesses across Rockwall, Royse City, Fate, Heath, Forney, and the surrounding DFW communities. Our certified AC technicians are trained to diagnose and repair all major system types and brands, from split systems and packaged units to central air conditioners of every age and configuration. We treat every air conditioner repair call with urgency because we know what it feels like to be without cooling when temperatures outside are pushing into the triple digits. When you call us, you reach a real person, we schedule your visit fast, and we show up prepared to fix the problem the same day in most cases.

An air conditioner that runs but blows warm air is one of the most common calls we receive, and it is almost always caused by one of a handful of fixable issues. Low refrigerant from a leak in the system is the most frequent culprit, as the system cannot cool properly without the correct refrigerant charge. A dirty or blocked condenser coil, a failing compressor, or a malfunctioning reversing valve on a heat pump system can also produce warm air output. Our technicians run a full diagnostic to pinpoint the exact cause before recommending any repair, so you are never paying to fix the wrong thing. If your AC is blowing warm air in Lavon, Rockwall, or anywhere in Rockwall County, call us and we will get a technician out to you quickly.

An air conditioner that will not turn on at all can be caused by something as simple as a tripped circuit breaker or a blown fuse, or something more involved like a failed capacitor, a faulty contactor, or a wiring issue in the control board. Before assuming the worst, our technicians work through a systematic diagnostic process to identify exactly where the fault is so the repair is targeted and efficient. In many cases, a non-starting AC can be repaired during the first visit because the components involved are ones we carry on our service vehicles. We always explain what we found and what the repair involves before we begin any work. If your air conditioner is not turning on, give us a call and we will get to the bottom of it fast.

An air conditioner that runs continuously but cannot bring your home to the set temperature is a sign that something in the system is underperforming. This could be a refrigerant issue, a clogged air filter severely restricting airflow, a dirty evaporator coil reducing heat transfer efficiency, or a system that is simply undersized for the space it is trying to cool. In older systems, compressor wear can also cause a gradual loss of cooling capacity that builds up slowly until the system can no longer keep pace on hot days. Our technicians assess both the equipment and the conditions in your home to make sure the diagnosis addresses the actual root cause. If your AC is running but not cooling your house down, we can typically identify and fix the problem in a single visit.

Water leaking from your air conditioner's indoor unit is almost always caused by a clogged condensate drain line, which is a very common and straightforward repair when caught early. If the drain line backs up completely, the overflow can cause water damage to ceilings, walls, and flooring, so it is worth addressing quickly rather than waiting. In some cases, a frozen evaporator coil can also produce excess water as it thaws, which points to an underlying airflow or refrigerant issue that needs to be addressed alongside the drain line. Our technicians clear the condensate drain, inspect the evaporator coil, and check for any contributing factors so the problem does not come back after the first repair. If you see water around your air handler or notice water stains on the ceiling below your unit, call us right away before the moisture causes secondary damage.

A frozen evaporator coil is a symptom, not a standalone problem, and fixing it requires identifying what caused it to freeze in the first place. The two most common causes are restricted airflow from a severely clogged air filter or dirty coil, and low refrigerant from a leak in the system. When the coil freezes, the system loses its ability to cool effectively and can eventually cause compressor damage if left running in that state. Our technicians allow the coil to thaw fully before performing a diagnostic so they can accurately assess refrigerant levels, airflow, and coil condition without the frost interfering with their readings. Once the root cause is identified and repaired, we verify the system is running correctly before closing out the call.

An air conditioner that repeatedly trips the circuit breaker is telling you something is drawing more current than the circuit can safely handle, and ignoring it is not a safe option. Common causes include a failing compressor pulling excessive amperage, a short circuit somewhere in the system's electrical components, a capacitor that is on its way out, or an undersized breaker that can no longer handle the load of an aging system. Each of these causes requires a different repair, which is why running a proper diagnostic before replacing any parts is essential. Our technicians check the compressor, capacitor, contactor, and all electrical connections to find exactly where the overcurrent is originating. If your AC keeps tripping the breaker, shut the system off and call us before running it again to avoid potential damage to the compressor or electrical panel.

Unusual noises from your air conditioner are almost always a warning sign that something mechanical is wearing out or has come loose, and catching it early usually means a simpler and less expensive repair. A banging or clanking sound often points to a loose or broken component inside the compressor or air handler. A squealing or screeching noise typically indicates a worn fan belt or a bearing that is failing in the blower motor. Rattling can be something as minor as a loose panel or debris that has worked its way into the unit, but it can also point to a loose mounting issue that puts stress on other components over time. Our technicians listen carefully, inspect all mechanical components, and identify the source of the noise accurately before recommending any repair. If your AC is making a sound it has not made before, call us and we will take a look before a minor issue turns into a major one.

Accurate diagnostics are the foundation of a good AC repair, and we take that step more seriously than any other part of the job. Misdiagnosing an AC problem leads to unnecessary part replacements, repeat service calls, and money spent on repairs that did not fix the actual issue. Our technicians work through a systematic diagnostic process every time, checking the full system before drawing any conclusions. We have seen every common AC failure mode and plenty of uncommon ones, and that experience shows up in the accuracy and efficiency of our repairs. When we tell you what is wrong with your system, you can trust that we have done the work to be sure.

We know that a broken AC in Texas is urgent, and we treat it that way. Our technicians stock the most commonly needed parts and components on their service vehicles so the majority of repairs can be completed during the first visit without waiting for a part to be ordered and shipped. When a specific part does need to be sourced, we let you know immediately with an honest timeline so you are never left wondering when your system will be back up. We also prioritize emergency repair calls for customers whose systems go down overnight or on weekends so you are not suffering through the heat any longer than necessary. Fast turnaround is something we deliver as a matter of routine, not something you have to specifically ask for.

Every AC repair we complete is priced transparently and presented to you in writing before we begin. The price we quote is the price you pay, and there are no additional fees added after the fact for things like fuel charges, after-hours premiums, or diagnostic costs that were not disclosed upfront. We believe customers deserve to know exactly what they are paying for before they agree to anything, and we hold ourselves to that standard on every single call. If we find additional issues during the repair that would add to the cost, we stop, explain what we found, and give you the choice of how to proceed. You are always in control of what gets done and what it costs.

Air conditioners do not break down on a convenient schedule, and neither do we. Our emergency AC repair service is available 24 hours a day, 7 days a week, including weekends and holidays, because we understand that a broken system at 11 PM in July is just as much of an emergency as one that breaks at noon. When you call after hours, you reach a real person, not a voicemail, and we dispatch a technician to your home as quickly as possible. There is no extra charge just for calling after hours because we think penalizing customers for having an emergency is not the right way to run a business. We are here whenever you need us, and that commitment does not have exceptions.

We are not a national chain that can absorb a few bad reviews and move on to the next market. We are a family-owned AC repair company based in Lavon, TX, and our reputation in Rockwall County is everything to us. That means every technician we send to your home is trained to our standards, every repair is completed with the care it deserves, and every customer is treated the way we would want our own family treated. When you hire Precision TX Heat & Air, you are hiring a company that has a genuine stake in your satisfaction, not just in closing the ticket. We stand behind our work, and we are here long after the job is done if you ever need us again.

One of the most common questions we hear before a service call is what the repair is going to cost. We understand why, and we always give customers as much clarity as possible before any work begins.

The honest answer is that AC repair cost depends on what is wrong with the system. Minor repairs such as a capacitor replacement, a contactor swap, or a condensate drain clearing are typically on the lower end of the cost range and can often be completed quickly during a single visit. Mid-range repairs such as a refrigerant recharge, a blower motor replacement, or an evaporator coil cleaning sit in the middle of the cost spectrum. Larger repairs involving a compressor replacement or significant electrical component work will cost more because of the parts and labor involved.

What we can promise is this: you will always receive a written estimate before we start any work. The price we quote is the price you pay. There are no hidden fees, no surprise line items, and no work begins without your explicit approval. If you want a general idea of what your specific repair might cost before we visit, call us and describe what your system is doing. We can often give you a useful ballpark over the phone based on the symptoms.

We also offer financing options for qualifying customers when a repair or replacement cost is more than expected. Ask us about available plans when you call.

How Long Does AC Repair Usually Take?

Most AC repairs are completed within a single service visit, which typically takes a few hours depending on the complexity of the issue and whether we have the needed part on hand. Our technicians stock commonly needed components on their vehicles to minimize return visits. If a specific part needs to be ordered, we give you an honest timeline upfront so you know what to expect. We prioritize getting your system back up and running as quickly as possible, especially during the hottest months of the year when going without cooling is not just uncomfortable but potentially dangerous for children, elderly family members, and pets.

Can I Run My AC While It Is Leaking Water?

We recommend shutting the system off if you notice active water leaking from your indoor air handler. Running the system while the condensate drain is backed up or while the evaporator coil is frozen can cause water to overflow and damage surrounding drywall, insulation, and flooring. It can also put additional strain on the compressor if the coil is frozen, potentially turning a simple drain clearing into a more expensive repair. Call us and we will get a technician out quickly. In most cases, a leaking AC is a straightforward repair that does not take long once a technician is on site

Why Does My AC Keep Tripping the Breaker?

A breaker that trips repeatedly when your AC runs is a sign that the system is drawing more current than the circuit can safely handle. This is not a problem to reset and ignore because repeated tripping can damage both the compressor and the electrical panel over time. The most common causes are a failing compressor, a weak capacitor, or a short circuit in the system's wiring. Each of these requires a different repair, which is why a proper diagnostic is essential before replacing any parts. If your AC keeps tripping the breaker, turn the system off and call us before running it again.

What Should I Do If My AC Stops Working at Night?

Call us. Our emergency AC repair service is available 24 hours a day, 7 days a week, including weekends and holidays. When you call after hours, you reach a real person who dispatches a technician to your home as quickly as possible. There is no extra charge just for calling outside of business hours. A broken AC at midnight in a Texas summer is a genuine emergency, especially for households with young children, elderly residents, or anyone with a health condition affected by heat. We take those calls seriously and respond accordingly.

Do You Work on All AC Brands?

Sometimes a repair is the clear answer. Other times, an honest look at the age and condition of your system points toward installation or replacement as the smarter long-term investment. We help you make that call without any pressure, and we have dedicated pages for both options if you want to learn more before deciding.

AC Installation If your home does not have an existing central air system or you are upgrading to a completely new setup, our AC installation page covers everything you need to know about the process, system options, and what to expect on installation day. Learn More About AC Installation

AC Replacement If your current system is aging, has needed repeated repairs, or is no longer cooling efficiently, replacement may be the better investment. Our AC replacement page walks you through how to know when it is time, what replacement costs look like, and how we handle the full process from removal to final testing.
