AC Installation & Replacement

HVAC Installation in San Antonio

Woman- & Family-Owned HVAC Service for Northern San Antonio Homes & Businesses

Westerly Air is a woman- and family-owned HVAC company serving Northern San Antonio with heating, cooling, and ventilation installations built around your specific home and climate. We size every system using advanced load calculation methods rather than rule-of-thumb estimates, so the equipment we install is matched to your space, not just close enough.

Our work covers the full range of HVAC needs: central air conditioner installation, heat pump systems, furnace installation, ductwork evaluation, and indoor air quality upgrades. Same-day service availability and installation warranties are standard.

Ready to replace an aging system or install new equipment? Call Westerly Air at (210) 361-2722 to schedule your assessment and free estimate.

Our Approach to HVAC Installation

Every installation starts with a personalized assessment. We walk through the home, evaluate the existing system, and account for square footage, insulation, window exposure, and San Antonio’s high-humidity summers before recommending any equipment. That process takes more time than a quick quote, and it’s why installed systems perform as designed.

Our technicians stay current through ongoing training, which keeps our installations aligned with changing efficiency standards and building codes. We respect your property throughout the process: clean work, clear communication, and no surprises on the invoice. If an emergency arises after installation, we’re available 24/7. Energy efficiency and affordability aren’t trade-offs we ask you to make; we work to deliver both.

Repair or Replace? How to Decide

Most residential heating and cooling equipment lasts between 10 and 20 years. When a system approaches or exceeds that range, the math on repairs often shifts. A compressor replacement on a 16-year-old unit can cost nearly as much as a new system that comes with a warranty and far better efficiency.

Watch for these signals that replacement makes more sense than another repair:

Frequent breakdowns requiring multiple service calls in a single season
Rising energy bills without a change in usage habits
Inconsistent temperatures from room to room, or a system that runs constantly without reaching the set point
Age over 15 years combined with any of the above

Older systems typically run at lower efficiency than equipment manufactured today. HVAC replacement in San Antonio doesn’t just restore comfort; it can lower monthly energy use.

Efficiency Standards & Permits for San Antonio HVAC Installation

SEER2 Requirements for Texas

Texas falls under the Department of Energy’s South Region efficiency standards. As of January 1, 2023, new residential split-system air conditioners under 45,000 BTU must meet a minimum 14.3 SEER2 rating. Heat pumps must meet both a 14.3 SEER2 and a 7.5 HSPF2 rating under the same regional requirement. SEER2 (Seasonal Energy Efficiency Ratio 2) is the updated federal testing standard that measures how efficiently a system cools relative to the energy it consumes; higher numbers can support lower operating costs.

Every system we install meets or exceeds these standards. Equipment is selected and calibrated to maintain consistent indoor temperatures while using less energy, which matters in a climate where air conditioners run for most of the year.

Mechanical Permits & Code Compliance

The City of San Antonio’s Development Services Department requires a mechanical permit for HVAC equipment installation and replacement. Standard residential changeouts can qualify for express permits issued same-day or within 24 hours, without a full plan review. We handle permit coordination as part of our installation process and stay current on city guidelines and building codes so your new system is positioned to pass inspection without delays.

HVAC Installation Across Northern San Antonio

We serve homeowners and businesses in San Antonio, Boerne, Cibolo, Schertz, and Timberwood Park. San Antonio’s climate brings hot, humid summers and occasional hard winter freezes, both of which place real strain on HVAC equipment. High humidity increases the workload on compressors and can accelerate wear on condensate drain lines. Correct system sizing accounts for those conditions from the start, which is why our load calculations are specific to each home rather than based on square footage alone.

Cost concerns stop a lot of homeowners from moving forward on a replacement they know they need. We offer financing options to make new equipment more accessible and provide free estimates when you schedule service. All installation work is backed by our service warranties.

Call Westerly Air at (210) 361-2722 to schedule your HVAC installation assessment. We can walk through your home, size the right system, and give you a clear picture of cost and timeline before any work begins.

What to Expect During a Westerly Air HVAC Installation

The process begins with a thorough assessment of your home’s heating and cooling needs. Our technicians evaluate the existing system, check ductwork condition, and gather the data needed for an accurate load calculation. Load calculation determines the correct equipment capacity by accounting for your home’s size, insulation levels, window area, local climate, and other factors. Skipping this step can lead to oversized or undersized systems that cycle inefficiently and wear out faster.

Once the right system is selected, installation is scheduled around your availability. After the equipment is in place, our technicians calibrate it to maintain optimal humidity levels indoors, which can help reduce conditions that support mold growth and keep the living environment comfortable year-round. Before we leave, we can walk you through system operation, explain the warranty coverage, and confirm everything is running as designed.
