Daggs Refrigeration A/C & Heat

Daggs Refrigeration A/C & Heat operates out of Houston as a veteran-owned HVAC outfit with more than forty-five years fixing and installing systems across the city. The crew handles both homes and commercial spots, keeping residential units running through the heat and maintaining larger setups for businesses that cannot afford downtime. Licensed and insured under TACLB18609E, they focus on straightforward repairs and installs without cutting corners or leaving guesswork behind. Owners and techs with decades on the job bring that experience to every call, whether it involves standard home comfort equipment or specialized refrigeration that keeps food and operations intact in local restaurants and shops.

They take on AC repair and full system installs, heating fixes, preventive maintenance, and diagnostics on everything from rooftop units to walk-in coolers and ice machines. In one case Helder reached a homeowner the same day after a thermostat glitch kept the furnace and AC running even when set to off, swapping the unit and confirming operation in under an hour. Another time he walked a new owner through their Ecobee controls and AC setup so the basics made sense before he left. For bigger jobs like a full residential install, the same tech worked through several options with the family, finished the work on schedule, and kept costs lower than bigger outfits while staying responsive throughout.

Homeowners keep coming back because the work shows up on time, costs stay fair, and the explanations come without pressure or extra charges. Reviews point to solid knowledge on multiple brands, quick arrivals even on urgent calls, and clean results that last whether the job was a simple thermostat swap or a complete new unit. The same pattern holds for commercial refrigeration where speed matters to protect inventory. DIRT Score 4.4 from 17 reviews on Finds.

“super nice, super fair guy… He understands that people want great service for a great price! (What a concept!) He has worked on my AC several times and am very happy with his knowledge and professional attitude! I have recommended his AC service to many friends and all are 100% happy! HIGHLY RECOMMEND!!!”

“5 stars, no question! Punctual , respectful, and very reasonably priced. As a new homeowner, I really appreciated that he took the time to explain how my Ecobee thermostat and AC unit work, not just fix them. He was thorough, knowledgeable, and made sure I understood everything before leaving. Excellent service, highly recommend !!!”

“Helder was great - he responded quickly to my Yelp request and came to investigate my AC issue (the furnace and AC were remaining switched on even though the thermostat was set to ‘Off’). He investigated the issue, replaced the thermostat and verified everything was working - all in less than 1 hour. Totally recommend :)”

“DGS was amazing. Helder worked with my family to try and find multiple solutions and then did an amazing job with our new AC install. They were prompt, professional, and responsive. Strongly recommend for anyone who wants to support a small local buisness that will give you a way better deal than those big companies.”

“Helder is awesome!! He came out quickly and went above and beyond to get our AC up and running asap! He is such a kind dude and will always be our go to for our heating and cooling needs!”
