Complete Guide to AC Installation in San Antonio
Proper AC Sizing for San Antonio Homes
In South Texas, proper AC sizing is critical. An undersized unit will run constantly and never cool adequately, while an oversized unit will short-cycle, causing humidity problems and premature wear. Our technicians perform Manual J load calculations that factor in your home's square footage, insulation levels, window placement, ceiling height, and the intense Texas heat. Most San Antonio homes require 2-5 tons of cooling capacity, but proper sizing can only be determined through professional calculation.
Understanding SEER Ratings
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently your AC converts electricity into cooling. The minimum SEER for new systems is 14, but for San Antonio's climate and high cooling costs, we recommend at least 16 SEER. Higher SEER systems (18-22) cost more upfront but can reduce your cooling costs by 30-50%. We'll help you calculate the payback period based on your home's specific usage patterns.
The Installation Process
Day 1 typically involves removing your old unit, inspecting and cleaning the installation pad, checking electrical connections, and preparing the site. Day 2 includes installing the new outdoor condenser, indoor air handler or furnace, connecting refrigerant lines, testing the system, and walking you through operation and maintenance. We also inspect your ductwork for leaks or damage that could reduce efficiency by up to 30%.
Choosing the Right System
Split systems (separate indoor and outdoor units) are most common and offer quiet operation. Package units (all components in one outdoor cabinet) are ideal for homes without indoor space. Variable-speed systems provide superior comfort and efficiency by adjusting output to match demand. As a Heil Elite Dealer, we specialize in premium Heil heating and cooling products and can recommend the best system for your budget and needs.
Ductwork Considerations
Even the most efficient AC won't perform well with leaky or improperly sized ductwork. During installation, we inspect all accessible ducts for leaks, proper insulation, and correct sizing. If your ductwork is more than 15 years old or shows signs of deterioration, we may recommend replacement or sealing to ensure your new system performs optimally.
Warranties and Maintenance
Most manufacturers offer 5-10 year parts warranties, and we provide a 1-year installation labor warranty. To maintain your warranty and ensure peak performance, we recommend annual maintenance. Our maintenance agreements include priority scheduling, discounted repairs, and extended warranty coverage. Regular maintenance can extend your system's life from 10-15 years to 20+ years.
Financing Your New AC System
We offer flexible financing options with approved credit, including 0% interest promotions during peak season. Monthly payments are often lower than the energy savings from replacing an old, inefficient system. Contact us at (210) 501-9445 to discuss current financing offers and calculate your potential savings.

As a Heil Elite Dealer, we install only premium, energy-efficient Heil heating and cooling equipment. Every installation includes manufacturer warranties and our exclusive 1-year installation labor warranty, giving you peace of mind that your investment is protected.
