AfterHVAC Company in Willis, TX
Willis sits just north of Houston in Montgomery County, where summers run hot from May through September and the clay soil shifts with every wet-dry cycle. That combination puts real strain on air conditioning systems and the slabs they sit on. We’re Dalton Heating & Air, and we handle AC repair, heat pump installation, and furnace repair across Willis with written pricing before any work starts. Call (361) 306-9515 when your system stops doing its job.
Why Willis Homes Are Different
Willis has grown in waves: older homes near the railroad tracks on the east side of I-45, manufactured homes and acreage properties off Calvary Road and Shepard Hill Road, and newer subdivisions like The Woodlands Hills pushing north along FM 1097. Each generation of housing puts different demands on HVAC equipment. The older units are often undersized for the square footage after additions went in. Manufactured homes run packaged units or split systems with ductwork in tight crawl spaces, and the humidity in Willis makes proper airflow the difference between a dry house and a mold-prone one.
The soil here is sandy loam over clay. When it dries out in July and August, slabs shift slightly, and refrigerant lines that run through walls or under floors can rub and leak. We see it in Willis regularly: a system that worked fine in spring loses its charge by mid-summer because a line set flexed against a shifting foundation. That’s a Willis-specific failure mode, and we look for it on every service call. The pine and oak canopy in neighborhoods near Lake Conroe also means pollen and fine dust load up outdoor coils faster than in open-area subdivisions, so coil cleaning matters more here than it does ten miles south.
Our Main Willis Services
Most calls we take in Willis fall into two buckets: an air conditioner that quit in the middle of a heat wave or a furnace that won’t fire when the rare cold snap hits. Here’s what each involves.
AC Repair in Willis
When your AC stops cooling in Willis, the first thing we check is airflow and refrigerant charge. The humidity here means a system that’s low on refrigerant will freeze the evaporator coil, and the homeowner sees water pooling by the indoor unit or warm air from the vents. We diagnose the leak, quote the fix in writing before touching anything, and repair it. Most AC repairs in Willis run $150 to $650 depending on the part. Our AC Repair in Willis page covers costs, symptoms, and what we check on every call.
Heat Pump Installation in Willis
A heat pump handles both cooling and heating, which suits Willis weather because most of the year you need air conditioning anyway. We size the unit to the actual load of the house, not a rule of thumb based on square footage. Homes in Willis with big west-facing windows or vaulted ceilings need more capacity, and undersized installs are the most common cause of short-cycling we see. Heat pump installation pricing is always a written fixed quote before the job is scheduled. Details on Heat Pump Installation in Willis, including brands and timelines.
Furnace Repair in Willis
Willis winters are short, but a failed furnace during a January cold snap is a hard no. The furnaces here are mostly natural gas, and the issues we see most are failed igniters, dirty flame sensors, and control boards aged out after ten or fifteen years. Furnace repair in Willis typically lands between $150 and $700 depending on the part. Every repair carries our written one-year guarantee. See Furnace Repair in Willis for a full breakdown of what fails and what it costs.
