CRT HVAC has been the go-to heating and cooling contractor in Hendersonville since 2011, and in fifteen years of service we have built a reputation that speaks for itself across Sumner County. We handle the full range of residential and commercial HVAC work, from a quick AC repair on a sweltering July afternoon to a complete system installation for a growing business. Whether you own a home on a quiet street in Hendersonville or manage a portfolio of commercial properties across the county, we are the crew you call when your heating or cooling needs attention. Family-owned. Locally rooted. Comfort is our business.
Whether it is a one-time repair or a full system replacement, we bring the same level of care and attention to every job. Our work covers the everyday HVAC needs that homeowners and property managers count on: air conditioner repair and service, furnace repair and heating service, heat pump repair and installation, full HVAC system installation and replacement, thermostat and smart-control installation, ductwork repair and sealing, indoor air quality and air filtration, and seasonal maintenance and tune-ups. This section is a quick map of what we do. Deeper detail on each service is just below. We show up ready to go to work.
Over the years, we have seen every kind of furnace, AC, and heat pump that Tennessee homes and businesses throw at us. When we started in 2011, we were a small operation with a single truck and a straightforward goal: do honest HVAC work for our neighbors and earn their trust one job at a time. Hendersonville was home, and we wanted to build something that reflected that.
Fifteen years later, that foundation is still the same. We have worked through Tennessee summers that push central air systems to their absolute limit, and through the sharp cold snaps that remind everyone in Sumner County just how important a reliable furnace or heat pump really is. We have served single-family homeowners, rental property owners, small business operators, and office and retail managers across the area. Every one of those jobs taught us something, and that experience shows in how we approach the work today.
We live and work in this community, and our work shows it. When you call us, you are talking to someone who knows these streets, understands the local climate, and genuinely cares how the job turns out. We keep you informed from diagnosis to final test, so there are no surprises and no guesswork on your end. Call and we will get your heat or AC back on.
For homeowners and property managers who want it done right, we cover everything a Tennessee home needs to stay comfortable through every season. Summers here are long and humid, and your central air system takes a beating from May through September. We handle AC repair and service for systems of all sizes and ages, and we install new central air equipment when a replacement makes more sense than another repair.
When temperatures drop, we are ready for that too. Furnace repair and gas furnace service keep your home warm through the cold months, and heat pump service and installation is an especially practical fit for the Tennessee climate, where mild winters and hot summers make heat pumps a reliable year-round option. For additions, sunrooms, or rooms without existing ductwork, mini-split and ductless systems are a clean solution we install regularly.
Beyond the big equipment, we also handle thermostat and smart-control installation, ductwork repair and sealing to improve efficiency and airflow, indoor air quality and air filtration upgrades, and seasonal tune-ups in the spring for your AC and in the fall for your furnace or heat pump. Keeping your system maintained is the simplest way to avoid the emergency call later.
Property managers and business owners have a different set of priorities, and we understand that. Downtime in a commercial space is not just uncomfortable, it is disruptive to your tenants, your customers, and your bottom line. We provide commercial AC repair and service, commercial heating repair, full commercial system installation and replacement, and ongoing commercial maintenance for offices, retail spaces, and rental properties throughout the Hendersonville area.
Our approach on commercial work is the same as residential: show up prepared, diagnose accurately, explain the options clearly, and get the system back online as fast as possible. Code-compliant HVAC work on every job is not a talking point for us, it is how we protect your property and keep your building operating without issue. Let us handle the install and the permits.
A system that goes down in the middle of a Tennessee summer or during a winter cold snap is not a problem you can schedule around. When your AC stops cooling or your furnace stops heating, you need someone who can get there fast and fix it right. We find it. We fix it. We test the airflow.
Same-day HVAC service is available for customers throughout Hendersonville and the surrounding area. We handle emergency AC repair when the heat becomes unbearable, emergency furnace repair when temperatures drop overnight, and after-hours calls when the problem does not wait for business hours. Our technicians come prepared to diagnose the issue on the first visit, whether that is a refrigerant leak, an airflow problem, uneven temperatures, or a system that simply will not start. The goal is always the same: get your home or business back to a comfortable temperature as quickly as possible.
Whether this is your first HVAC repair or your tenth, the pricing conversation should never be uncomfortable. We believe in giving you a clear, honest picture of what the work involves and what it will cost before anything gets started. No surprise fees, no add-ons that appear after the fact, and no pressure to approve work you are not ready for.
That approach applies across everything we do: AC repair, furnace repair, heat pump installation, ductwork sealing, thermostat installation, and full system replacement. When we quote a job, we explain what we found, what we recommend, and why. If there are options at different price points, we walk you through them so you can make the decision that fits your situation. Call for a quote and you will know exactly where things stand before any work begins.
Hendersonville is our home base, and we are proud to serve the homeowners and businesses here every day. Our service area extends across Sumner County and into the surrounding communities, including Gallatin, Goodlettsville, White House, Millersville, Portland, and Madison. If you are nearby and need HVAC work done, there is a good chance we have already worked in your neighborhood.
Knowing the area matters in this trade. We understand the housing stock, the commercial buildings, and the seasonal demands that come with living in this part of Tennessee. That local knowledge makes us faster, more accurate, and better equipped to get the job done right.
We are not satisfied with a job until you are. If something is not right after we leave, we want to know about it and we will make it right. That is not a policy written on a wall somewhere; it is how we have operated since the beginning. Fifteen years of repeat customers and word-of-mouth referrals in Hendersonville tells us that approach works.

How do I know if my system needs a repair or a full replacement?
A system that breaks down repeatedly, is more than 15 years old, or has repair costs approaching the price of new equipment is usually a better candidate for replacement. We assess the full system during a service visit and give you an honest recommendation based on what we find. We walk you through the options so you can make the decision that fits your situation and your budget.
What are the signs that my AC or furnace is starting to fail?
Common signs include the system running longer than usual without reaching the set temperature, uneven heating or cooling from room to room, unusual noises like banging or rattling, a sudden increase in energy costs, or the system cycling on and off more frequently than normal. Any of these is worth a diagnostic call before the problem gets worse.
How often should I schedule maintenance and tune-ups?
We recommend a spring tune-up for your air conditioner before cooling season and a fall tune-up for your furnace or heat pump before heating season. Two visits per year keeps the equipment running efficiently, catches small problems early, and helps extend the useful life of the system.
Same-Day and Emergency Availability
When your heat or AC goes down, you should not have to wait days for help. We offer same-day service for both emergency and routine calls in Hendersonville and across Sumner County.
Is same-day service really available, or is that only for emergencies?
Same-day service is available for both emergency and non-emergency calls when our schedule allows. No-heat and no-cool situations get priority, but we do our best to get to routine repair and service calls quickly as well. Call (615) 697-8932 and we will tell you what we can get on the schedule for today.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures are often caused by ductwork leaks or disconnected sections, an undersized system, blocked or closed vents, or a thermostat that is not placed well. In some cases, zoning controls or a ductless mini-split for a problem area is the right solution. We diagnose the cause before recommending a fix.
What do strange noises from my HVAC unit usually mean?
Banging or clanking often points to a loose or broken component inside the unit. Squealing can indicate a worn belt or bearing. Rattling may mean debris in the system or a loose panel. Clicking that continues after startup can signal an ignition or electrical control issue. If your system is making a noise it did not make before, it is worth a call.
Transparent Upfront Pricing
We tell you what we found and what it will cost before any work begins. No surprise charges after the fact, and no work proceeds without your approval.
How do ductwork leaks raise my energy bills?
When conditioned air escapes through gaps or disconnected duct sections before it reaches the living space, your system has to run longer to hit the thermostat setting. That extra run time shows up directly on your energy bill. Sealing the ductwork lets the equipment deliver the air you are already paying to condition, rather than losing it in the walls or attic.
Should I choose a furnace or a heat pump for my Hendersonville home?
Tennessee's climate, with mild winters and long hot summers, is well suited to heat pumps. A heat pump handles both heating and cooling with a single system, which simplifies maintenance and can reduce operating costs. In homes that already have a furnace and ductwork in good shape, a matched furnace-and-AC replacement is also a solid option. We can walk you through the comparison based on your specific home and existing equipment.
Code-Compliant Work on Every Job
Every installation and repair is performed to code. We handle permits where required and make sure the work is done right the first time, whether it is a single repair or a full system replacement.
How does whole-home humidity control differ from a portable dehumidifier?
A portable dehumidifier handles one room at a time and requires you to empty the reservoir or run a drain line manually. A whole-home dehumidifier integrates directly with your HVAC system, manages humidity throughout the house automatically, and does not require ongoing attention. In Sumner County's humid summers, the whole-home approach is more consistent and far less work.
How do estimates and pricing work before a job starts?
We provide a clear estimate before any work begins, based on what we find during the diagnostic visit. If something unexpected comes up once work is underway, we stop and walk you through it before proceeding. We do not add charges after the fact without your knowledge and approval.
Do I need to be home when the technician arrives?
For most interior work, yes. Someone should be present to provide access to the equipment and to hear what we find during the visit. Being on-site also lets us walk you through the diagnosis and the proposed repair before we start, which is how we prefer to work. For exterior-only work, we can discuss the specifics when you call.
