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.
