What your neighbors are saying about us

Patrick was very professional! I cannot recommend him highly enough, and whatever company he is working for. I very much liked their maintenance plan. He explained it very well and we purchased it. I highly recommend this plan, this company and this technician.

We absolutely love Hunters for all our electrical needs. We had originally called them out bc someone redoing our floors had burned up an outlet. Christopher was very knowledgeable and polite. He explained all recommendations that he had in a way that I understood. They are the only company I will use for all our electrical needs and upgrades.

I am very pleased with the service I've received from Hunter Service Group. Stacy was kind, respectful of my home, and professional. The install was performed in a timely fashion and I couldn't be more pleased. I will use Hunter Services for any future needs that I have within your scope! Thank you!

I highly recommend Hunter Service Group. We have recently worked with Noe Garcia and Tony Ruiz to help my in-laws find the right home generator for them to add some peace of mind if the power goes out. Installation should take place in the next few weeks. It has been a great experience so far.

Signs It's Time for a New HVAC System

Most HVAC systems last between 15 and 20 years, but in San Antonio’s climate, heavy use can shorten that lifespan. If your system has been running hard through summer after summer, it may be giving you signs that replacement makes more sense than another repair. Watch for:

Your system is 15 years old or older and struggling to keep up.
Repair costs are adding up and approaching the value of a new system.
Your energy bills keep climbing even though your usage hasn’t changed.
The system runs constantly, but still can’t maintain a comfortable temperature.
You’re dealing with uneven cooling or hot spots in certain rooms.
The unit uses R-22 refrigerant, which is no longer manufactured and is costly to source.

HVAC Systems We Install and Replace

Hunter Service Group installs and replaces a full range of residential HVAC equipment. Every home is different, and we take the time to match you with a system that fits your home’s size, layout, and cooling and heating demands. We work with all major brands and install:

Central air conditioning systems for whole-home cooling.
Gas and electric furnaces for reliable winter heating.
Heat pump systems that handle both heating and cooling efficiently.
Ductless mini-split systems for homes without existing ductwork or for zoned comfort.
Air handlers and coil replacements as part of a full system upgrade.

Our HVAC Installation and Replacement Process

We don’t believe in rushing through an installation. A system that’s sized and installed correctly from the start will run more efficiently, last longer, and keep your home more comfortable than one that was thrown in quickly. Here’s how our process works:

We start with a thorough assessment of your home to determine the right system size and type for your specific needs. From there, we walk you through your options with honest recommendations and upfront pricing before any work begins. On installation day, our technicians handle everything from removing the old equipment to connecting and testing the new system. Before we leave, we make sure everything is running properly and take the time to answer any questions you have about your new system.

Benefits of Upgrading to a New HVAC System

Replacing an aging system isn’t just about staying cool. A modern, properly sized unit can improve your home in several ways, especially given how much San Antonio homeowners rely on their HVAC throughout the year. Benefits of upgrading include:

Lower monthly energy bills thanks to improved efficiency ratings on newer equipment.
More consistent comfort throughout your home with better airflow and temperature control.
Reduced humidity levels indoors, which matters in San Antonio’s muggy shoulder seasons.
Fewer breakdowns and repair costs with a new system under manufacturer’s warranty.
Access to smart thermostat compatibility and better indoor air quality features.
Peace of mind knowing your home is covered during the hottest months of the year.

Frequently Asked Questions

How do I know what size HVAC system my home needs?

Proper sizing requires a load calculation based on your home’s square footage, insulation, window placement, and other factors. An oversized or undersized system will run inefficiently and wear out faster. Our technicians perform this assessment before recommending any equipment.

How long does an HVAC installation take?

Most residential installations are completed in one day. The timeline can vary depending on the type of system and whether any ductwork modifications are needed, and we’ll give you a clear expectation before we start.

Is it better to repair or replace my HVAC system?

If your system is under 10 years old and the repair is straightforward, fixing it usually makes financial sense. If it’s older, requiring frequent repairs, or significantly less efficient than modern equipment, replacement is often the smarter long-term investment.

What HVAC brands do you install?

We work with all major residential HVAC brands. During your consultation, we’ll recommend equipment based on your home’s needs, your budget, and what we know holds up well in San Antonio’s climate.

Will a new HVAC system help with indoor humidity?

Yes. A properly sized modern system does a much better job managing indoor humidity than an older or oversized unit. This is especially noticeable during San Antonio’s humid spring and fall seasons when moisture control matters just as much as temperature.
