Heating & Cooling in Horseshoe Bay, Texas

Texas heat is a season-long endurance test — Horseshoe Bay air conditioners routinely run from March to November, and grid-stressing summer peaks make efficient, well-maintained equipment pay for itself. Sudden winter freezes have also proven that reliable heating can't be an afterthought. Local providers like Gunderson Heating & Cooling understand these conditions and service equipment accordingly.

Common HVAC Problems in Horseshoe Bay

Weak airflow from vents

Weak or uneven airflow usually points to a clogged filter, leaky ductwork, or a failing blower motor. Left alone it forces the system to run longer and drives up energy bills.

Uneven temperatures between floors

Multi-level homes often suffer hot upstairs rooms in summer. Duct adjustments, zoning dampers, or a ductless unit for the problem area are common solutions.

Furnace ignition failures

A furnace that clicks but will not light may have a dirty flame sensor, faulty igniter, or gas supply issue — problems best diagnosed by a trained technician.

Strange noises at startup

Grinding, squealing, or banging at startup often signals worn bearings, a loose blower wheel, or delayed furnace ignition — all worth addressing before they become breakdowns.

Why Choose a Local Texas Company

Understanding the regional climate means recommendations sized for real conditions, not national averages. Established local providers stand behind their work long after the invoice is paid. Local companies live on reputation, and word travels fast in the community when work is done right.

Seasonal Tips for Texas Homes

Keep the condensate drain line clear; in humid climates algae builds fast and an overflow can shut the system down mid-summer.
Watch humidity, not just temperature: a system that cools but does not dehumidify may be oversized or low on refrigerant.
Rinse the outdoor condenser coil each spring — in long cooling seasons a dirty coil can cut efficiency by double digits.
Set ceiling fans to run counterclockwise in summer so you can raise the thermostat a couple of degrees without losing comfort.

Frequently Asked Questions

Should I repair or replace my system?

A common rule: if the unit is past 12 years old and the repair costs more than a third of replacement, replacement usually wins. A technician can weigh age, efficiency, refrigerant type, and repair history for your specific unit.

Do heat pumps work in Texas?

Modern cold-climate heat pumps perform well across Texas's typical temperature range, and they both heat and cool. The right fit depends on your home's insulation and existing ductwork.

Is emergency HVAC service available?

Many local providers, including Gunderson Heating & Cooling, take urgent calls — a failed furnace in winter or dead AC in a heat wave should not wait. Call (830) 953-1116 to check availability.

What size HVAC system does my home need?

Sizing depends on square footage, insulation, windows, ceiling height, and local climate — not guesswork. An oversized unit short-cycles and an undersized one never keeps up, so a proper load calculation matters.

Why is my AC running constantly in summer?

During heat waves some runtime is normal, but nonstop operation with poor cooling suggests low refrigerant, dirty coils, duct leaks, or an undersized system. A service visit can pinpoint which.
