Celina is one of the fastest-growing cities in the United States. The city added over 12,700 residents in a single year and nearly quadrupled in size since 2020. Along almost every block, new homes are going up – master-planned communities like Ramble, Light Farms, Mustang Lakes, and the Uptown Celina district are adding thousands of new homes to a city that barely registered on most maps a decade ago. All those homes need HVAC service, and Adon Complete Air Conditioning and Heating has provided heating and air conditioning service in Celina, TX, for years from our home base just down Preston Road in Anna. We’re available 24 hours a day, 7 days a week.
What Celina Homeowners Need from an HVAC Company
Most of Celina’s new homeowners move in with brand-new systems. That sounds like a good thing, and it is, but new systems still need attention. Builder-installed equipment needs to be commissioned and maintained on schedule to keep warranties valid. Ductwork in new construction can have debris from the build process that should be cleaned out. And when something goes wrong in year two or three, you need a company that knows what it’s doing and shows up fast. Here’s what we handle in Celina:
AC Repair. We diagnose and repair all makes and models. Celina’s new construction runs heavy on Trane and Lennox systems – we’re factory-trained on both as a Trane Comfort Specialist.
AC Installation. For Celina homeowners replacing a system or adding cooling to a bonus space, we size everything correctly and back every installation with up to a 10-year labor warranty.
HVAC Maintenance. The Adon Care Club is $12 a month. It includes two seasonal tune-ups, priority scheduling, repair discounts, no diagnostic fees, and 24/7 emergency access. For new construction homeowners, a maintenance plan is one of the best ways to protect your builder warranty and catch problems before they get expensive.
Mini-Split Installation. Celina’s newer homes often have garages, home offices, or bonus rooms that the central system doesn’t reach well. Mini-splits handle these spaces cleanly without modifying the existing ductwork.
Heat Pump Installation and Repair. Heat pumps are becoming more common in Celina’s newer builds. They handle both heating and cooling from one unit and work well in North Texas’s climate.
Indoor Air Quality. New construction homes are sealed tight for energy efficiency, which means less fresh air exchange than older homes. Air filtration systems, UV purifiers, and ventilators make a real difference. We offer Celina homeowners a free “What Are You Breathing?” screening.
Air Duct Cleaning. Construction dust and debris inside new ductwork is common and worth addressing in the first year or two. Professional duct cleaning improves both air quality and system efficiency.
Air Duct Repair and Sealing. Leaky ducts cost you 20 to 30 percent of your system’s output. We find and fix them throughout Celina and Collin County.
We’ve Been in Celina Since Before the Boom
Adon Complete has been running calls in Celina for years. We were here when Light Farms was still breaking ground and when Mustang Lakes was the new neighborhood everyone was talking about. We know the neighborhoods, the builders, and the systems they put in. That matters because when something goes wrong with your Trane or Lennox in year two or three, you want someone who’s already worked on dozens of them in your zip code, not someone who just added Celina to their service map because the city showed up on a census report.
Owner Jesse Villarreal has over 27 years of HVAC experience and is directly involved in every aspect of the business. We’re a Trane Comfort Specialist and Mitsubishi-authorized dealer, which means factory-trained installation and the full manufacturer warranty on every system we install. We service everything, not just the brands we put in. And the Adon Care Club at $12 a month is the most straightforward maintenance plan in the area – two tune-ups, priority scheduling, repair discounts, no diagnostic fees, and 24/7 emergency access.
Serving Celina’s Newest and Most Established Neighborhoods
We service all of Celina, including Light Farms, Mustang Lakes, Ramble, the Uptown Celina communities, and the established neighborhoods near downtown and Celina High School. We also serve the surrounding communities of Prosper, Frisco, McKinney, Anna, and Allen throughout Collin County.
Questions We Hear From Celina Homeowners
My home is brand new – why is my AC already having problems?
New systems fail for a few reasons. Builders sometimes install builder-grade equipment quickly and don’t commission it as carefully as they should. Ductwork connections can work loose. Drain lines get clogged in the first season. And in a city growing as fast as Celina, HVAC subcontractors are stretched thin. None of this means your system is a lemon – it usually means it needs a proper inspection and a few corrections. Call (903) 482-4900 and we’ll take a look.
Does getting on a maintenance plan actually protect my builder warranty?
In most cases, yes. Most HVAC manufacturers require proof of annual maintenance to keep extended warranties valid. If something fails at year four and you can’t show a maintenance record, the manufacturer can deny the claim. Our Adon Care Club provides documented seasonal tune-ups that satisfy that requirement. It’s one of the most overlooked things new homeowners skip in the first year.
What’s the difference between what the builder installed and what you would recommend?
Builders typically install equipment that meets code and keeps the home price competitive. That’s not necessarily bad equipment, but it’s rarely the most efficient option, and it’s not always sized precisely for the home’s specific load. When we come out for a maintenance visit, we’ll give you an honest read on what you have, what’s working well, and what might be worth upgrading down the road. No pressure either way.
How do I know if my new home’s ductwork needs cleaning?
If your home was built in the last three years, construction dust, drywall particles, and other debris likely made its way into the ductwork during the build. You won’t always see it, but it circulates through your system every time the air runs. We recommend professional air duct cleaning in the first year or two for most Celina homeowners in new construction. It’s a one-time investment that improves both air quality and system performance.
Do you offer emergency HVAC service in Celina?
Yes. We’re available 24 hours a day, 7 days a week. When you call after hours, you reach a real person, not a voicemail. We regularly run calls in Celina, so getting someone out quickly isn’t a problem. Call (903) 482-4900 any time.

Got with Jesse for an estimate. Customer accepted pricing. Just wanted to get with financing. Jesse will be speaking about about them With financing by tomorrow at nine in the morning. System is currently running at this time.
Arrived on site and found system running completely. Leak outside was due to water heater not ac system. Home owner rejected Complete service to system so no other payments would be added.

Replacement of condenser fan motor under parts only warranty. Installed new motor and verified all bolts are tight. Wired up new motor to contactor and capacitor. Tested system after repair. Measured amp draw on fan motor, it is within acceptable range. There is still a bit of vibration and all the screws are tight. This was caused from when the unit was running with the unbalanced motor. Everything is running correctly, it’s just a little noisier than when it was new.
2 system AC maintenance. Set thermostats to cool and checked temperature drop across systems. Checked operation of drain lines, they are clear and we treated them with drain solution. Filters are a bit dirty and should be replaced soon. Drain lines have safety shut off switches. Next, went outside to condensers. Checked amp draw on compressors and fan motors. Both systems have hard start kits installed. Both capacitors and contactors are testing within acceptable range. Cleaned condenser coils using water. Both systems are cooling at this time.
Arrive for no cool on single system. Customer stated that system was making very loud noise and not cooling. She had another company out in June, they said the fan blade was not balanced so they cleaned it. Turned system on and system started shaking badly. Took top off and found that motor shaft had a ton of play in it. Fan motor needs to be replaced. Condenser is under warranty until 2028.
Arrive for no cool on downstairs system. Thermostat was set to cool and both outside and inside units are running. Checked refrigerant pressures and system is low on refrigerant. Went into attic and checked temperature drop, only getting 5° difference. Noticed oily residue on copper piping going into coil. Let customer know we will need to perform a leak search to verify where the leak is that way it can be properly fixed. Customer declined leak search at this time and will give us a call back a little later to have work done.
No cool on zoned system. Indoor blower was running but condenser was not. Condenser was making a humming sound. Checked capacitor and it is completely dead. Replaced capacitor with new one that comes with 5 year warranty. Tested system after repair. Measured amp draw on compressor and fan motor. System is cooling at this time.
Performed one system maintenance and found no issues. I did notify the homeowner that the capacitor is getting a little low for the fan. It was reading a 4.8 out of 5. I performed a dryer vent cleaning. Dryer vent is now clear. I tested drain lines. Drain line is clear and system is running properly at this time.
Performed one system maintenance found that the capacitor at the outdoor unit was running low Informed homeowner that the capacitor was low, he will wait on this. System is running properly and drain line was clear
