What Van Alstyne Homeowners Ask Us For Most
Van Alstyne has a mix of established properties, acreage homes, and newer construction that’s come in along the US-75 corridor. Here’s what we handle most often in this area:
AC Repair. When something stops working, we diagnose it correctly the first time. We carry common parts on our trucks and handle all makes and models.
AC and Heating Installation. Whether you’re replacing aging equipment or putting in a system for a new build or addition, we size everything correctly and back it with up to a 10-year labor warranty.
HVAC Maintenance. The Adon Care Club is $12 a month. Two tune-ups a year, priority scheduling, repair discounts, no diagnostic fees, and 24/7 emergency access. A lot of our Van Alstyne customers have been on this plan for years.
Mini-Split Installation. Shops, garages, outbuildings, and sunrooms are common on Van Alstyne properties. Mini-splits are the practical solution when running ductwork isn’t an option.
Heat Pump Installation and Repair. Heat pumps handle both heating and cooling from one system. Worth considering for Van Alstyne homeowners who want to reduce their energy costs year-round.
Indoor Air Quality. Older homes in Van Alstyne can have dust and air quality issues that newer construction doesn’t. Air filtration, UV purifiers, and duct cleaning make a real difference. We offer a free screening to Van Alstyne homeowners.
Air Duct Cleaning. Older ductwork accumulates years of debris. Professional cleaning improves air quality and helps your system run more efficiently.
Air Duct Repair and Sealing. Leaky ducts are common in older homes and can account for 20 to 30 percent of your system’s lost output. We find and fix them.
A Few Things Worth Knowing About How We Work
We don’t price-gouge during emergencies. One of our Van Alstyne customers specifically mentioned this after we came out during an ice storm. That’s not a policy that changed when things got difficult. That’s just how we’ve always operated.
We explain what we find before we fix it. Several of our Van Alstyne reviews specifically mention that our technicians took time to explain what was happening with the system. You shouldn’t have to take a technician’s word for it without understanding what you’re paying for.
We come back until it’s right. One Van Alstyne customer noted that we returned multiple times during a difficult heating issue until it was fully resolved. That’s the standard we hold ourselves to.
Owner Jesse Villarreal has been in this business for over 27 years. We’re a Trane Comfort Specialist and Mitsubishi-authorized dealer. We service everything regardless of brand.

Adon Air is always quick to respond anytime we call. Alex was our repair technician. It is apparent that he is very knowledgeable with AC diagnosis/repair. He was also very courteous and took the time to explain everything that he was doing.

Job Locations
1 system heating maintenance. System is electric heat pump. Measured amp draw on blower motor. Checked temperature rise across coil with heat pump and emergency heat strips. Measured amp draw on emergency heat strips, all are functioning. Treated drain line using Total C. Went outside to condenser and measured amp draw on compressor and fan motor. Checked capacitor and contactor, both are testing within acceptable parameters. System is operational at this time.
1 system heating maintenance. System is electric heat only. Replaced filter provided by customer. Recommended adding insulation in attic. Attic only has about 7 in of insulation at this time. Recommended upgrading to a heat pump system to help the cost of electricity as well. Homeowner was interested in dryer vent cleaning. All estimates have been sent.
Arrive for no Cool on zone system. Thermostat had critical error on it, stating no communication with outdoor unit. Went to main breaker panel and found that breaker for outdoor unit was turned off. Customer had tried to reset breakers and accidentally left the condenser breaker off. After powering on condenser, communication was reestablished. After five minute delay, system started cooling. Upstairs and downstairs zones are both cooling at this time.
No cool on cassette type unit. System was set to cool and compressor would run for a second and then turn off after about 3 min. Unable to find connection to check pressure. System is R22, unable to make any repairs due to refrigerant type. Told customer best option is either a mini split or window unit. Both would be able to handle the cooling load of the building.
Customer wanted us to check out condensers to see if they needed to be combed. Checked all 6 condensers and the fins are not damaged or smashed together at all. The only thing we recommend is cleaning the condensers. They have a bit of dirt buildup on the coils.
Need to order correct board and come back
No cool on mini split serving garage area. Set thermostat to cool. Indoor blower came on and compressor was running but fan motor would not work. Took covers off to reveal circuit board. Found board burnt where it had arched and even left a black mark on cover above it. Need to replace circuit board under parts warranty.
Return trip to see why system is not cooling as efficiently as it should. Checked temperature drop across system, getting 17° difference instead of 20° like we want. Checked refrigerant pressures, subcooling and superheat. System appears to be a little low on refrigerant. Discussed different options with customer. Also discussed adding insulation to the attic, this will help keep the house at temperature as well as prevent the system from overworking. Emailed estimates to customer and she is going to get back to us if she would like to move forward with any of the work. System is cooling at this time.
Arrive for no cool on downstairs system. Customer had concerns about system keeping up with temperature. When they woke up this morning it was down to the set temperature. Also, when we arrived it was set to 73 and it was currently 73 in the house. Customer stated that he didn’t think enough air was coming through supply vents. Checked temperature drop across system and getting 22° difference. Filter was a bit dirty, recommended getting it replaced to make sure that doesn’t cause any inefficiency. Coil is clean and insulation inside cabinet is still attached. There are no dampers on supply plenum. Felt air coming out of supply grill and it seemed like the correct amount of air for the system. Getting 54° at supply grill. Thermostat schedule for sleep is set to 71° at 10:00. Everything is checking out correctly. System is cooling at this time.
HVAC System Evaluation & Recommendations During today’s service visit, we identified several items that need attention to improve the home’s comfort, efficiency, and HVAC system performance. Attic Insulation The attic currently has little to no adequate insulation. We recommend adding insulation to achieve a minimum depth of approximately 14 inches. Proper attic insulation will help reduce heat transfer, improve indoor comfort, and allow the HVAC system to operate more efficiently. Return Air Cleaning & Sanitizing The return-air area has a significant buildup of dirt and debris. We recommend a deep cleaning and sanitizing of the return area to remove accumulated contaminants and improve overall system cleanliness and airflow. Air Filter Required At the time of service, the system did not have an air filter installed. It is very important that the proper air filter be installed and replaced regularly to protect the evaporator coil, blower assembly, and overall HVAC system. Outdoor
