Moving to New Braunfels? Your HVAC Guide for the First Texas Summer
About 5,000 new residents move to New Braunfels every year, many from drier climates. Central Texas summers are not just hot; they are aggressively humid. Here is what that means for your system, what to look at the week you move in, and how to find a contractor you can trust before you are calling one in an emergency.
What Central Texas heat is actually like
The average July high in New Braunfels is 96–98°F, with a heat index routinely 105–110°F. Humidity adds 10–15 degrees of perceived heat versus drier climates. AC season runs April through October — seven months of cooling load.
A system sized for Seattle or Denver may be undersized here. Central Texas load calculations account for latent (humidity) load, not just temperature. An undersized system runs continuously without reaching setpoint — that kills compressors within two to three seasons.
What to check when you move in
Find the data plate on the outdoor unit. In most brands the first two digits of the serial number are the manufacture year. Note the refrigerant type and SEER or SEER2 rating.
- System 10+ years old — plan for replacement within your ownership horizon.
- Running R-22 — phased out in 2020. Budget for replacement.
- Running R-410A — new-system manufacturing banned Jan 1, 2025. Repairs will get pricier.
- Locate and check the filter immediately — a clogged filter is the #1 preventable summer service call.
- Short cycling — runs under 10 minutes per cycle in peak heat.
- Ice on the refrigerant lines.
- Standing water in the drain pan.
Build your contractor relationship before you need it
Book a pre-season tune-up in April: coil cleaning, refrigerant pressure check, capacitor test, drain-line flush, thermostat calibration. Typical cost is $75–$150. Why April? Summer backlog means 3–5 day waits in July; April calls get same-week slots. Emergency replacement decisions made under a 110°F heat index are rarely the optimal financial choice.
How to find a vetted contractor as a newcomer
98% of consumers use the internet to find local businesses — but unlicensed contractors advertise freely online too. Nextdoor and Facebook group recommendations are a useful starting point, not an endpoint. Always verify the license at tdlr.texas.gov/verify.htm — see our how-to-choose guide.
of consumers trust referrals from friends and family over any other source. Ask neighbors who have lived in New Braunfels through at least one summer.
What your first maintenance visit should cover
- Filter replacement
- Coil inspection and refrigerant pressure
- Drain-line flush and capacitor test
- Thermostat calibration and blower-motor check
Ask the technician: what refrigerant type does this system run? What is the manufacture date? Is there anything I should watch before next summer? What is your response time for emergency calls in July?
