AfterHVAC Company in Schertz, TX
Dalton Heating & Air handles HVAC repair and installation across Schertz, TX, from the neighborhoods along FM 1518 to the subdivisions east of I-35. Most Schertz homes run their air conditioning hard from May through September, and when a system fails mid-summer, the indoor temperature climbs fast. We answer the phone 24/7, give you a written price before any work starts, and back every repair with a full-year written guarantee. Call (361) 306-9515 when your system stops doing its job.
Why Schertz Homes Are Different
Schertz sits on the northeastern edge of the San Antonio metro, and the housing stock tells the story of a city that grew in waves. You’ll find 1970s and 1980s single-story ranch homes in older sections, 1990s and 2000s two-story builds in master-planned communities, and newer construction pushing toward Marion and the Cibolo Creek corridor. That spread of ages matters for HVAC work. Older homes often have ductwork-sized for original equipment, which means a new high-efficiency system sometimes needs duct modifications to breathe properly. Newer homes are sealed tighter, which changes humidity control and airflow requirements. A one-size-fits-all diagnosis doesn’t hold up here.
The other Schertz factor is geography. The city covers nearly 30 square miles, stretching from the I-35 corridor west toward Randolph AFB and east past FM 3009 into the rolling terrain near Cibolo. Summer temperatures routinely push past 100°F, and the humidity from the Gulf makes systems work harder than they would in a dry climate. That combination of heat, humidity, and mixed housing age means we see specific patterns: capacitor failures and contactor burnouts in older units, refrigerant leaks in systems that never got proper maintenance, and airflow problems in homes where additions or remodels changed the load without resizing the equipment. Schertz jobs reward a technician who actually looks at the whole system, not just the part that failed.
Our Main Schertz Services
Most calls from Schertz homeowners fall into two camps: air conditioning systems that quit working in the heat, and furnace or heat pump decisions that come up during the mild winter stretch. Each service has its own Schertz page with pricing and details.
AC Repair in Schertz
When an air conditioner fails in Schertz in July, it isn’t a minor inconvenience. Indoor temperatures in a closed-up house can reach the high 90s within hours, and that’s a health concern for older residents, infants, and anyone with respiratory issues. Our AC Repair in Schertz page covers the most common failures we see here: refrigerant leaks, capacitor failures, frozen evaporator coils, and compressor problems. We service all major brands, diagnose the actual fault, and put the repair price in writing before we touch a component. Most Schertz AC repairs are completed in a single visit.
Heat Pump Installation in Schertz
Schertz winters are short but occasionally sharp, and more homeowners are replacing aging electric furnaces or straight-cool AC units with heat pumps that handle both heating and cooling. The Heat Pump Installation in Schertz page walks through sizing, equipment options, and what a proper install includes. Schertz homes with ductwork sized for an older AC-only system sometimes need airflow adjustments to get full heat pump performance. We handle the load calculation, the equipment selection, and the installation as one job with a fixed written price and a set install date.
Furnace Repair in Schertz
Most Schertz homes run gas furnaces or heat pumps for the handful of genuinely cold weeks between December and February. When a furnace won’t light or a blower motor gives out, you want it diagnosed correctly the first time. The Furnace Repair in Schertz page details the failures we see most often: ignitor problems, flame sensor faults, gas valve issues, and blower motor failures. Every furnace repair from Dalton Heating & Air includes a written price before work begins and a written one-year guarantee after it’s done. If the repair fails within that year, we come back at no charge.

Brands We Service in Schertz
Our technicians are factory-trained on the equipment most common in Schertz homes, and we stock parts locally for the brands we service. That means fewer two-trip repairs and less waiting for a part. We see a lot of Trane, Lennox, Goodman, and Rheem in Schertz closets and attics, and our trucks carry the capacitors, contactors, ignitors, and control boards those systems use most. When a part isn’t on the truck, it’s usually available locally the same day.
Pricing for HVAC Company in Schertz, TX
Here are the price ranges Schertz homeowners should expect for the most common HVAC jobs. These are written-price ranges, not lowball estimates that shift once the work starts.
| Service | Typical Range in Schertz |
|---|---|
| AC Repair (minor: capacitor, contactor, thermostat) | $150 – $350 |
| AC Repair (major: blower motor, refrigerant leak, fan motor) | $350 – $650 |
| Furnace Repair (minor: ignitor, flame sensor, limit switch) | $150 – $350 |
| Furnace Repair (major: gas valve, blower motor, control board) | $350 – $700 |
| AC Installation (mid-efficiency, standard ductwork) | $3,500 – $5,500 |
| AC Installation (high-efficiency, variable-speed) | $5,500 – $7,500 |
| Preventive Tune-Up (standard inspection and cleaning) | $80 – $150 |
| Tune-Up (multi-point with diagnostics and testing) | $150 – $200 |
What pushes a Schertz job toward the higher end of these ranges is usually access: attic-installed air handlers in tight two-story homes, older ductwork that needs modification, or equipment that was never maintained and has multiple worn components. Whatever the final number, it’s in writing before we start. No surprises at the door, no add-ons after the fact.

Yes. Schertz has housing stock ranging from 1970s ranches to homes built within the last few years, and the equipment needs differ by era. Older homes often need duct or airflow work to support modern equipment, while newer sealed homes need attention to humidity control and ventilation. We assess the specific house, not just the machine.
