The NSG story
“Fort Worth's best-kept secret.”
Nick & Maria built NSG on a stubborn idea: HVAC should be designed, not dropped in. We design each install around the house and its airflow, because a well-sized system on bad ductwork is still an uncomfortable home.
That discipline is why our customers stay customers for life — and why we put a two-year labor warranty in writing and register every system we install, so you keep the manufacturer's full ten-year parts coverage.
- 01 Measure We size the system to your actual house.
- 02 Design Airflow planned room by room: returns, ducts, zoning. The equipment is chosen last, not first.
- 03 Install Clean, custom installations, set up for perfected airflow.
- 04 Stand Behind It Our 10-Year Parts & 2-Year Labor Warranty in writing. We register your new equipment with the manufacturer to lock in the full 10-year parts coverage, and back our own workmanship for 2 years.
Accountability, in writing
10 years on parts. 2 years on labor.
Your new equipment carries a 10-year manufacturer parts warranty — but only if someone registers it. Skip that step and coverage quietly drops to five years, so NSG registers every system we install. Then we back our own workmanship with a 2-year labor warranty. If our work ever causes a problem in that window, the fix is on us. Not you.
Featured manufacturer
Carrier equipment, installed and registered by NSG
NSG's featured manufacturer is Carrier. Ask us which Carrier air conditioner, furnace, heat pump, or ductless system fits your home, and we'll register it so your 10-year manufacturer parts warranty is in place.

In our customers' own words
Fellow contractor
“Nick and his crew are absolutely the best in the industry. I have been an HVACR contractor for over 40 years and just too old to work on my own equipment. He is the only guy I trust to work on my equipment”
Emergency repair
“NSG Heating and Air Specialists, LLC. responded to my A/C concern promptly and had us up and running within hours. They were very professional and honest. Highly recommend! Thank you for being a trusted company that we can count on.”
Replacement
“Nick and his crew are top notch! They recently replaced our outside unit. They evaluated our system one day and had it running again the next. I am so thankful that I had a working heater through the winter storm we just endured.”
Maintenance plan
“Have been using NSG for the past 4 years. Their service team is spectacular…..!! Service calls are quick and efficient. Have the annual maintenance plan – tech’s only replace parts as needed, but always advise “what we need to keep an eye on” Highly recommend”
Weekend repair
“NSG is a reliable company. They repaired my ac on a weekend early in the morning. The price was affordable and the job was done quickly and correctly. The technician Juan was super friendly and polite. Would recommend this company in a heart beat. Thank you!”
Install
“This was one of the most professional and knowledgeable groups I’ve done business with. Nick and Ricardo were awesome. Quality work, quick, and really worked with scheduling. I’d recommend NSG to anyone needing HVAC repair, maintenance, or systems. Great company and people.”
Same-day fix
“My AC unit decided to die on Saturday for an unknown reason. Called these guys early Monday morning and they were able to get out to me same day was an easy repair. Being in the middle of a Texas summer I appreciate they were able to get this done very quickly.”
