Trusted AC Services

Specialty HVAC Solutions for the Situations Central Systems Cannot Always Handle

Not every heating and cooling challenge in a home is solved by a standard central air system, and not every efficiency improvement requires replacing the equipment you already have. Precision TX Heat & Air is a family-owned HVAC company based in Lavon, TX, and we offer a range of specialty HVAC services designed to address the specific situations where a targeted solution delivers better results than a one-size-fits-all approach. Whether you need to add cooling to a room addition that your central system cannot reach, upgrade to a smart thermostat that gives you better control and lower energy bills, or clean years of accumulated debris out of your ductwork, our certified technicians handle each of these services with the same care and attention to quality that we bring to every job. If you have an HVAC need that does not fall into the standard categories, call us and we will tell you honestly whether it is something we can help with and what the best approach looks like for your specific situation.

Our Specialty HVAC Services

Each of the services below addresses a specific situation or need that our customers encounter regularly. We have dedicated sections for each one so you can find exactly what you are looking for and understand what the service involves before you call.

Mini Split Installation 

Efficient, Flexible Heating and Cooling Without the Need for Ductwork

A mini split air conditioner, also called a ductless mini split, is a heating and cooling system that delivers conditioned air directly to a specific space without requiring ductwork, making it the most practical solution for room additions, garages, workshops, sunrooms, converted attics, and any other space that your central HVAC system cannot efficiently serve. Mini split systems consist of a compact outdoor compressor unit connected to one or more indoor air handlers mounted on the wall or ceiling of the spaces being served, and they can provide both heating and cooling from a single installation depending on the model selected. We handle the complete mini split installation process including system selection, refrigerant line installation, electrical connections, and final startup and testing so the system is ready to use from the day we finish the job. Mini split AC systems are significantly more energy efficient than window units or portable AC systems and provide much better comfort control because they are sized and positioned correctly for the space they are serving. If you have a room or space in your home that your central system has never been able to keep comfortable, a ductless mini split installation is very likely the right solution.

Ductless AC Installation 

Add Cooling to Any Space in Your Home Without Touching the Existing Ductwork

Ductless air conditioner installation is one of the most requested specialty services we provide because so many homes in the Lavon and Rockwall County area have spaces that were added or converted after the original HVAC system was installed and that were never properly connected to the central cooling system. A garage that has been converted to a living space, a sunroom that bakes in the summer heat, a room addition that sits at the end of a long duct run and never gets adequate airflow, or a detached workshop that needs climate control are all ideal candidates for a ductless AC installation. The installation process is significantly less invasive than extending existing ductwork because it requires only a small penetration through the wall for the refrigerant lines and electrical connections rather than opening walls and ceilings to route new ducts. We assess the space, recommend the right capacity system for its size and sun exposure, and complete the full installation with minimal disruption to your home. Ductless AC is also available in heat pump configurations that provide both heating and cooling, making it a year-round solution for the spaces it serves.

Smart Thermostat Installation 

Better Control of Your HVAC System and Lower Energy Bills Starting the Day It Is Installed

A smart thermostat gives you precise control over your home's heating and cooling schedule from anywhere using your phone, learns your preferences over time and adjusts automatically, and provides detailed energy usage reports that help you understand exactly where your heating and cooling dollars are going. Many homeowners in Lavon and Rockwall County are still running manual or basic programmable thermostats that do not communicate with their HVAC system in the way that modern equipment is capable of, and upgrading to a smart thermostat is one of the simplest and most cost-effective ways to improve both comfort and energy efficiency without replacing any major equipment. We handle the complete smart thermostat installation including compatibility assessment, wiring, setup, and app configuration so the thermostat is fully functional and connected to your home network before we leave. Different smart thermostat models have different compatibility requirements depending on your HVAC system's wiring configuration, and we make sure the thermostat we recommend is genuinely compatible with your equipment rather than leaving you to figure out a compatibility issue after the purchase. We also walk you through how to use the thermostat and set up the scheduling features so you start capturing energy savings from day one.

Duct Cleaning 

Remove Years of Accumulated Dust, Debris, and Contaminants From Your HVAC System

The ductwork in your home is the distribution system through which your HVAC system delivers conditioned air to every room, and over time it accumulates dust, pet dander, pollen, mold spores, insulation particles, and other debris that get recirculated through your living spaces every time the system runs. Professional duct cleaning removes this accumulated buildup using specialized equipment that dislodges and extracts debris from the full length of the duct system, including supply ducts, return ducts, and the air handler itself, delivering measurably cleaner air and in some cases improving system airflow and efficiency. Duct cleaning is particularly valuable for homes that have recently undergone construction or renovation, homes where visible mold growth has been identified inside the ductwork, homes that have experienced rodent or insect infiltration of the duct system, and homes where occupants have been experiencing unexplained allergy symptoms or respiratory irritation. We assess the condition of your ductwork before recommending a cleaning so we are not selling you a service your ducts do not actually need, and we use commercial-grade equipment to complete the cleaning thoroughly rather than with a shop vacuum and a brush. After cleaning, we inspect the duct system for any leaks or damage that may be contributing to efficiency or air quality issues and provide written recommendations for any repairs that are warranted.

Ductwork Repair and Sealing 

Leaky Ducts Are Quietly Costing You Money Every Time Your System Runs

Leaky ductwork is one of the most common and most underdiagnosed sources of energy waste in homes across North Texas, and the Department of Energy estimates that duct leakage can account for 20 to 30 percent of the conditioned air a system produces being lost before it ever reaches the living spaces it was intended to serve. The result is an HVAC system that runs longer than it should, rooms that never quite reach the set temperature, and energy bills that are higher than they need to be month after month. We inspect ductwork for leaks, disconnected sections, and inadequate insulation, and we seal and repair identified issues using mastic sealant and foil tape applied to the correct locations rather than a temporary fix that will fail again within a season. Duct sealing is particularly impactful in homes with older flex duct that has become loose at the connections over time, homes where ducts run through unconditioned spaces like attics or crawlspaces, and homes where certain rooms have always been difficult to heat or cool regardless of thermostat settings. We provide a written estimate for any ductwork repairs before starting and document what was sealed and where so you have a record of the work completed.

HVAC System Zoning 

Stop Heating and Cooling Rooms You Are Not Using and Start Controlling Comfort Room by Room

HVAC zoning divides your home into independently controlled areas, each with its own thermostat, so you can heat or cool the spaces you are actually using without wasting energy on unoccupied rooms or struggling with the temperature differences that naturally occur between different areas of a multi-story home. A common example is a two-story home where the upstairs bedrooms are consistently warmer than the downstairs living spaces because heat rises, and a single thermostat cannot satisfy both areas simultaneously without overcooling one or overheating the other. Zoning systems install motorized dampers inside the existing ductwork and connect them to a central control panel that manages airflow to each zone independently based on its own thermostat reading. We assess your home's layout, duct configuration, and existing HVAC equipment to determine whether zoning is a practical and cost-effective solution for your specific comfort challenges and provide a written estimate that covers the full scope of the installation. Zoning is one of the most effective ways to improve both comfort and energy efficiency in a home without replacing the existing HVAC system, and for the right home it delivers a meaningful and immediate improvement in how the system performs.

WHY CHOOSE US

Why Homeowners in Rockwall County Choose Us for Specialty HVAC Services

Specialty HVAC services require a different kind of expertise than standard repairs and installations. Here is what makes Precision TX Heat & Air the right choice for these less common but equally important services.

Every specialty HVAC service we perform starts with an honest on-site assessment of your specific situation. We do not recommend a mini split system without measuring the space and evaluating the sun exposure, insulation, and usage patterns of the area being served. We do not recommend duct cleaning without first inspecting the ductwork to confirm that a cleaning is actually warranted. We do not sell a zoning system without evaluating whether your existing equipment and duct configuration can support it correctly. This assessment-first approach means the solutions we recommend are genuinely appropriate for your home rather than a standard product we push regardless of whether it is the right fit. Our goal is to solve your problem correctly, not to sell you the most expensive option available.

We Assess Before We Recommend

Some HVAC companies will sell you a mini split unit or a smart thermostat but leave the installation as your responsibility to figure out. We handle the complete installation process for every specialty service we offer, including all electrical connections, refrigerant line installation for mini splits, app configuration for smart thermostats, and damper installation and system programming for zoning. This matters because a product that is not installed correctly does not perform the way it should, and in some cases an incorrect installation voids the manufacturer warranty. When we complete a specialty HVAC installation, you have a professionally installed, fully functional system that is ready to perform from the first day and covered under its full manufacturer warranty.

We Handle the Full Installation, Not Just the Product

Hand cursor tapping a checkmark next to an X icon on a white background

Mini split systems, zoning controls, and smart thermostats have specific installation and configuration requirements that differ from standard HVAC equipment, and working on them correctly requires technicians who have genuine hands-on experience with these products rather than reading the installation manual for the first time on your job. Our certified technicians are trained on the specialty products and systems we install, and they bring that experience to every job. For mini split installations in particular, proper refrigerant line sizing, correct line set routing, and accurate refrigerant charging are all critical to long-term system performance, and these steps require a technician who knows what they are doing.

Our Technicians Are Certified and Experienced in IAQ Products

Hand cursor tapping a checkmark icon beside an X icon on white background

Every specialty HVAC service we complete is priced transparently and documented in a written estimate before we start. You know exactly what you are paying for, why it costs what it costs, and what is included in the scope of the job before we schedule anything. If we encounter something during the job that affects the scope or cost, we stop, explain what we found, and get your approval before proceeding. There are no surprise line items on your final invoice and no work begins without your explicit agreement to the estimate. We also offer financing for qualifying customers on larger specialty installations like mini split systems and zoning, so cost does not have to be a reason to put off a solution your home genuinely needs.

Transparent Pricing With No Surprises

Our commitment to customers does not end when the installation is complete. If your mini split is not performing the way you expected, if your smart thermostat is not communicating with the system correctly, or if your duct cleaning revealed an issue that needs follow-up attention, call us. We stand behind every specialty service we complete and we follow through on that commitment because our reputation in Rockwall County depends on customers who feel well taken care of long after the job is closed. We are a local company with a genuine stake in the satisfaction of every customer we serve, and that accountability does not change based on the size or type of the job.
