Fresh-Air Systems

Fresh-Air Systems handles HVAC work across the Northwest San Antonio area from their base in Selma, Texas. They focus on home AC installation, routine maintenance visits, full system replacements, and heating services that include furnace repairs along with insulation upgrades. Emergency calls are accepted when units break down outside regular hours, and every new installation carries a one-year warranty on labor and parts. The company stays small enough that the owner stays involved in most jobs rather than sending crews that rotate through different houses each day. Homeowners in the region deal with extreme summer heat and occasional winter cold snaps, so reliable HVAC support keeps indoor conditions steady without repeated callbacks.

Derek, the owner, shows up for service calls and gives straight evaluations that lead to purchases of complete heating and cooling systems after honest discussions about what each house actually needs. One long-term customer stayed with the company for over four years after Derek first diagnosed issues and laid out clear options instead of pushing unnecessary work. Another homeowner had a blower fan fail and watched the crew complete the repair while submitting all the required paperwork to a home warranty provider before leaving the property. Heater service calls get the same attention, with the team explaining what failed and what the fix involves so owners understand the outcome. These smaller-company habits show up in how they handle both quick fixes and larger replacements without cutting corners on the details.

Customers keep coming back because the work holds up through Texas weather swings and the crew explains every step without rushing anyone. Reviews highlight the reliability of the repairs on AC units and heating equipment, the extra effort to manage warranty forms on site, and the clear communication that leaves homeowners confident the job is done right. Speed matters when a system quits during peak heat, yet the quality of the installation and maintenance keeps repeat business strong without constant price complaints. The honest approach from the owner down through the technicians builds trust that lasts years rather than one-off visits. DIRT Score 4.87 from 86 reviews on Finds.

“Have been a customer for 4 plus years now. Derek, the owner, came out on a service call about four years ago, gave me the most honest advice and evaluation and I told him he had my business for life. We have purchased two heating and cooling systems, based on very thoughtful recommendations. Service calls have an exceptionally quick turn around time, and even preventative maintenance has been easy. Yes, a unit is an investment, but terms and payment plan were outlined and done with the right amount of courtesy to what we could afford. With what our need were and what Derek recommended, it turned out exactly as he said and we started to see the benefits within 12 months. Any time a/c needs come in the radar, a homeowner is just in the most stressful position. Without a doubt Fresh Air Systems has never ever made me feel that way in the least.”

“I have fidelity national home warranty and was assigned Fresh Air systems for my blower fan going out. They are a smaller company but they know what they are doing. They are willing to go the extra mile and took the time to submit paperwork to my home warranty company while still at my house leading to an expedited review. Juan was my technician and he explained what was wrong and even looked to see if the part was in stock before he left my house.”

“Shafer Mechanical delivered outstanding service from start to finish! Their technician, Eric, did an excellent job working on our boiler system. He was professional, knowledgeable, and took the time to explain everything clearly so we felt confident in the work being done. The system is running better than ever, and you can tell he truly cares about quality and customer satisfaction. It’s not every day you come across someone who takes such pride in their work. Highly recommend Shafer Mechanical—and if you get Eric, you’re in great hands”

“Derek has been the best in HVAC service. Very intelligent and knows what he’s talking about and brings it down to the customers’ level if need be. The utmost in true service and reliability in his job. Respectful, kind and honest! He also did service for our heater last fall. He is the man for your HVAC needs!”

“Fresh Air Systems was excellent. They quickly diagnosed and fixed my mothers AC issue and had everything running perfectly again. The team was professional, knowledgeable, and efficient from start to finish. Highly recommend them if you want the job done right.”
