Why San Antonio Chooses TSG

When your comfort is on the line, you need a team that shows up fast, gets it right, and stands behind every job. For over two decades, TSG has been the service company San Antonio families call first and the one they recommend to their neighbors.

How do you determine the right size system for my home?

We perform a Manual J load calculation before recommending any equipment. This takes into account your home’s square footage, ceiling height, insulation levels, window orientation, sun exposure, and local climate data. In San Antonio’s extreme heat, proper sizing is critical. An oversized unit short-cycles and leaves your home feeling humid. An undersized unit runs constantly and never catches up. We get it right before installation begins.

How long does a residential HVAC installation take?

Most standard installations are completed in one day — typically between 4 and 8 hours. If the project requires additional ductwork modifications or a complete system overhaul, it may take two days. We’ll give you a clear timeline before we start.Most standard installations are completed in one day — typically between 4 and 8 hours.

What brands do you install?

We install all major brands including Carrier, Trane, Lennox, Rheem, Goodman, and others. We’ll recommend the best option based on your budget, your home’s characteristics, and long-term efficiency goals — not commission.

Does the installation include removing my old equipment?

Yes. We disconnect and remove your old system as part of the installation process. We handle disposal responsibly — you don’t have to worry about what to do with the old unit.

Is a permit required for HVAC installation in San Antonio?

Yes, in most cases a permit is required. TSG Services handles all permitting and inspections on your behalf as part of the installation. Everything is done by the book, which also protects your warranty and your homeowner’s insurance.

Do you offer financing?

Yes. A new HVAC system is a significant investment, and we offer flexible financing options so you can get the equipment you need today without straining your budget. Contact us to find the plan that works for you.

What warranty comes with the installation?

New equipment comes with the manufacturer’s warranty — typically 5 to 10 years on parts depending on the brand and model. We also back our labor. Ask us about extended warranty options when you schedule your consultation.
