HVAC Repair & Heating Services | Precision TX Heat & Air

Precision TX Heat & Air is a family-owned heating and air conditioning company based in Lavon, TX. We are not a franchise operation or a call center routing jobs to strangers. We are your neighbors, and we have been taking care of homes and businesses across Rockwall County and the greater DFW area with the kind of honest, personal service you just do not get from the big companies.

Our certified HVAC technicians handle everything your home needs, from repairing a refrigerant leak in your split-system air conditioner to replacing an aging gas furnace before winter arrives. Whether you are in Lavon, Rockwall, Royse City, Fate, or Forney, we are close by and ready to help.

We also believe everyone deserves comfortable air in their home, which is why we offer special discounts for veterans, active duty military, first responders, and teachers. It is our way of giving back to the people who give so much to this community.

When your air conditioner stops cooling, you need a reliable repair team that shows up fast and gets it right the first time. Our technicians diagnose and fix refrigerant leaks, failed capacitors, frozen evaporator coils, faulty contactors, and compressor issues across all major brands and system types. We know how brutal a North Texas summer can get, and we treat every AC repair call like the urgent situation it is. Most repairs are completed the same day, and we always give you a clear estimate before any work begins. We serve homeowners throughout Lavon, Rockwall, Royse City, and the surrounding DFW area.

Whether you are building a new home, adding central air to a space that never had it, or upgrading to a more efficient system, we handle AC installation from start to finish. Our team helps you choose the right size and model for your home's square footage, layout, and budget so you are not paying to cool more than you need to. We work with all major brands and complete every installation to manufacturer specs and local code requirements. Proper installation is one of the biggest factors in how well your system performs and how long it lasts, and we take that seriously. When the job is done, we walk you through the new system and make sure everything is running exactly as it should before we leave.

If your air conditioner is more than 10 to 15 years old and keeps breaking down, you may be spending more on repairs than the system is worth. We provide honest repair versus replace assessments so you never sink money into a system that has already run its course. Our technicians walk you through your replacement options including efficiency ratings, system types, and what makes the most sense for your home and budget. We handle the full removal of your old unit and the complete installation of the new system, so you never have to coordinate with multiple contractors. Getting a newer, more efficient system often means lower energy bills from day one, and we are here to help you make that transition smoothly.

A furnace that stops working in a North Texas winter needs fast attention, and our team is available around the clock to make sure you are not left in the cold. We repair gas furnaces, heat pumps, and boilers across all makes and models, diagnosing problems like short cycling, cold air output, ignition failures, cracked heat exchangers, and unusual noises. Our technicians carry commonly needed parts on their service vehicles so many repairs can be completed during the first visit. We explain what we found, what we are doing to fix it, and what you can expect going forward before we start any work. Whether it is a quick fix or a more involved repair, we handle it with the same care and professionalism every time.

We install furnaces, boilers, and heat pumps for homes throughout Rockwall County and the greater DFW area, handling everything from system selection to final testing. Our technicians help you evaluate your home's heating load so the new system is properly sized, because an oversized or undersized unit will cost you more money in the long run. We work with all major heating system brands and complete every installation to local building codes and manufacturer guidelines. If you are considering switching from a traditional gas furnace to a more energy-efficient heat pump, we can walk you through exactly what that process looks like and whether it is a good fit for your home. Every installation includes a full system startup and walkthrough so you know how to operate and maintain your new equipment.

Older heating systems lose efficiency season by season, and the energy bills you are paying to run them often cost more than a replacement would over time. We provide transparent furnace replacement cost estimates and take the time to explain what is driving the cost so you can make a fully informed decision. Our team handles boiler replacement and heat pump replacement as well, so regardless of what type of heating system you have, we have you covered. We remove your old equipment, install the new system, and leave your home clean and your system running before we wrap up the job. If you are not sure whether it is time to replace or if a repair might buy you a few more good years, we give you an honest answer with no pressure either way.

Regular maintenance is one of the simplest and most cost-effective things you can do to keep your HVAC system running reliably through the hottest summers and coldest winters Texas throws at you. Our AC tune up service includes a full inspection of all major components, evaporator and condenser coil cleaning, refrigerant level check, electrical connection testing, and a written condition report you can keep for your records. Our furnace tune up covers the heat exchanger, burners, ignition system, blower motor, and all safety controls to make sure your heating system is ready before temperatures drop. We also offer HVAC maintenance plans that provide scheduled seasonal tune ups, priority scheduling, and discounts on any repairs we find along the way. Customers on a maintenance plan consistently see fewer emergency breakdowns and longer equipment lifespans than those who skip regular service.

HVAC emergencies do not wait for business hours, and neither do we. Our emergency AC repair and emergency furnace repair services are available every hour of every day, including weekends and holidays, because we know a broken system in extreme weather is not something you can put off until Monday morning. When you call, you reach a real person, not an answering machine, and we dispatch a technician to your home as quickly as possible. We cover emergency calls across Lavon, Rockwall, Royse City, Fate, Heath, Forney, and the surrounding DFW communities. Whether your AC quit at midnight or your furnace went out during a holiday weekend, call us at (972) 322-7560 and we will be on our way.

Reliability is not a bonus feature for us, it is the baseline expectation we hold ourselves to on every single call. When we schedule a service appointment, we arrive on time and come prepared with the tools and parts to handle the job properly. We respect the fact that you rearranged your day to be home, and we do not take that for granted. If anything changes on our end, we call you ahead of time, not after we have already missed the window. Showing up when we say we will is one of the most basic ways we earn your trust, and we take it seriously.

Before we touch anything in your home, we tell you exactly what is wrong, what we recommend, and what it will cost to fix it. We do not use pressure tactics or try to upsell you on repairs or parts your system does not actually need. If a simple repair is the right call, we tell you that even when a full replacement would be a bigger ticket for us. Our goal is to give you the information you need to make the best decision for your home and your budget, and then let you make it. Honest communication is something we believe every customer deserves, and it is the standard we hold our technicians to on every visit.

Every member of our field team is a licensed HVAC technician with hands-on experience diagnosing and repairing all major system types, including split systems, packaged units, heat pumps, gas furnaces, and boilers. We stay current on manufacturer training and industry certifications so our team is equipped to work on newer high-efficiency systems as well as older equipment. We do not send inexperienced technicians to handle complex diagnostics on their own. When we show up to your home, you are getting a professional who knows what they are looking at and knows how to fix it correctly. That consistency in quality is something we are proud of and something our customers count on.

Our commitment to quality does not end when we pull out of your driveway. If something is not right with the work we completed, we come back and make it right without debate or delay. We back our repairs and installations because we are confident in the quality of our work, and because we know our reputation in this community depends on it. Rockwall County is not a big anonymous city where you can do subpar work and just move on. These are our neighbors, and we intend to keep earning their trust long after the job is done.

We are proud to offer special service discounts for veterans, active duty military, first responders, and teachers across our service area. These are the people who show up every day to protect, serve, and educate this community, and we believe they deserve a company that gives something back. When you call to schedule your service, just let us know which discount applies to you and we will make sure it is reflected in your estimate. This is one of our favorite parts of being a locally owned company because we get to say thank you in a tangible way. It is a small gesture compared to what these folks do, but it is one we are committed to offering for as long as we are in business.

A new HVAC system or a major repair is a significant investment, and we do not want the cost to stand between you and a comfortable home. We offer financing options for qualifying customers so you can move forward with the work you need now and pay for it over time in a way that fits your situation. Our team walks you through available financing plans during your free estimate so you know what your options are before making any decisions. There is no pressure to use financing, but it is there for the customers who need it. Getting your home comfortable should not have to wait, and with flexible payment options, it does not have to.

We had a great experience with Precise TX Heat & Air! We recently had to replace the unit for our master bedroom, and Chris was incredibly knowledgeable, professional, and easy to work with. He communicated with us every step of the way! I've already referred them to one of my clients, and they were just as happy with the service. It's always nice to have a company you can confidently recommend. Highly recommend

I can't recommend Precision TX Heat and Air enough. They have always handled my issues and do a great job. This morning, I woke up to 81 degrees in my house because it was blowing heat/ I called them, and they were out here this morning and fixed the issue, which was the thermostat operating improperly. Earlier this year, I had other issues with the unit being 15 years old and the way the drip pan was originally installed, and everything was taken care of.

How Much Does HVAC Repair Cost?

The cost of HVAC repair depends on what is wrong and what parts are needed to fix it. Minor repairs like a capacitor replacement, a clogged condensate drain, or a faulty thermostat connection are typically on the lower end of the cost range. Larger repairs involving a compressor, heat exchanger, or evaporator coil will cost more because of the parts involved. We always provide a written estimate before any work begins so there are no surprises on your invoice. If you want a ballpark before we visit, give us a call and describe what your system is doing and we can give you a general idea over the phone.

How Long Does AC Installation Take?

Most standard central air conditioner installations are completed in a single day. Jobs that involve adding new ductwork, upgrading the electrical panel, or installing a more complex system type may take a day or two depending on the scope. We walk you through the full expected timeline during your free estimate appointment so you can plan accordingly. Our team works efficiently and cleans up after the job so your home is back to normal as quickly as possible. If anything comes up during the install that would extend the timeline, we communicate with you right away.

When Should I Replace My AC Unit?

If your air conditioner is more than 10 to 15 years old and has been needing frequent repairs, replacement is usually the better long-term investment. A helpful rule of thumb is to multiply the age of the unit by the estimated repair cost. If that number exceeds 5,000, a new system typically makes more financial sense than continuing to repair the old one. Newer systems are also significantly more energy efficient, which means lower monthly utility bills that can help offset the upfront cost of replacement over time. We provide honest repair versus replace assessments at no charge so you can make a confident decision with clear information.

How Often Should My HVAC System Be Serviced?

We recommend scheduling an AC tune up once a year before summer and a furnace tune up once a year before winter. Regular maintenance keeps your system running at peak efficiency, extends its overall lifespan, and gives our technicians a chance to catch small issues before they turn into costly emergency repairs. Homeowners who skip annual service tend to see more unexpected breakdowns and shorter equipment life compared to those who stay on a regular maintenance schedule. Our HVAC maintenance plan makes it easy to stay on top of seasonal service without having to remember to call every year. Ask us about plan pricing and what it includes when you book your first service.

Why Is My AC Not Cooling My House?

There are several common causes for an air conditioner that runs but does not cool properly. Low refrigerant from a leak in the system is one of the most frequent culprits, as is a dirty or clogged air filter restricting airflow through the unit. A frozen evaporator coil, a failing capacitor, or a compressor that is beginning to lose efficiency can all produce the same symptom of warm air coming through your vents. The right diagnosis makes all the difference between a quick inexpensive fix and an unnecessary parts replacement, which is why we always run a full diagnostic before recommending any repair. Give us a call and we can typically get a technician out the same day to identify exactly what is going on.

Do You Offer HVAC Financing?

Yes, we offer financing options for qualifying customers on new HVAC installations and larger repair jobs. We understand that a major system repair or a new installation is not always something you can budget for on short notice, and we want to make sure cost does not keep you from getting the service your home needs. Available financing plans are reviewed with you during your free estimate so you can see your options before making any commitments. There is no obligation to use financing, and we never pressure customers into it. Just ask when you call and we will walk you through what is available.
