We are a third generation business that originally started out as a small sheet metal shop and metal roofing company. W. Fred Long opened the business in 1927 and later passed it to his son Ronald J. Long, Sr. in 1971, who passed it to his sons Steven and Joel in 2005.

As the company expanded over the years, we took to duct fabrication, commercial roofing, and commercial and residential HVAC. Because HVAC is the largest percentage of energy used in homes, we thought it was a natural progression to add an energy related division to the business.

We are very excited to have the opportunity to expand and are even in the process of opening a customer care center where all of our sales, marketing, accounting, and training operations will be located.

Dr. Energy Saver Charlotte offers homeowners energy efficient products and services. We can provide you with efficient lighting, replacement windows and doors, water heaters, insulation, air sealing, help with water conservation, sources for renewable energy, and much more to help you save money.

We have helped many homeowners pay less for energy bills by making their homes more energy efficient. Our comprehensive home energy efficiency solutions are customized to fit your specific needs.

  • I would recommend this business

I had my crawlspace encapsulated last week by GSM Services. The whole process from being scheduled to completion was smooth. Stoney Davidson and his whole crew deserve praise. They worked hard cleaning out my crawlspace and preparing it for the encapsulation. This is my 2nd house I have had encapsulated by GSM and I would highly recommend their services. I have also had a new HVAC system installed last year. Everyone from the office staff to the techs who perform the job are top notch!

  • I would recommend this business

New arrival in Gastonia and the first deep cold snap I had no heat; just the fan blowing. Aux heat did not function and the compressor disconnects below a certain temperature.
Called GSM after checking their many 5 star reviews. They did not disappoint.
10 minutes into the visit their tech found the problem: a loose connection in the thermostat. No expensive parts needed, just 10 second tightening of a tiny screw!
The tech and his assistant were excellent. Fast, friendly and professional.
Gsm will always be my first call when I have a HVAC problem! No wonder they've been in business so long.

Customer Testimonials

The representative, Wayne King, explained clearly the different options available. We were able to follow his presentation easily and he answered our questions readily for further clarification. The crew, the Driscoll brothers and their co-worker arrived at the dates and time scheduled. They were very professional, cordial, gave updates in between and did an excellent job. I recommend them highly.


Just wanted to mention that GSM has serviced my Heat & Air for (4) years. Wayne King sent Kyle Heffeman and some crew to replace the unit last week because (it gave up the ghost). 18 yrs old. They did a fantastic job and put everything back in order all in one day. The new system works great! I highly recommend GSM, they even service our work facility and have done a wonderful job over the years. Very professional and friendly.


It was a great experience with GSM from start to finish! Kelly did a great job in explaining our options and making suggestions without pressuring us. Kyle H. and his partner (I'm sorry I don't remember his name!) did a fantastic job with the installation. They were friendly, professional and had our new system installed faster than I could have imagined! Kyle did a thorough job in explaining our new thermostat and the system works really well. I highly recommend GSM!


My heat went out today on the coldest day of the year. I called GSM and they were right out here. Robert Shook and his helper were awesome. Then had Jim Smith come out because we ended up needing a new ac unit and a new furnace. He went above and beyond to help us with financing. The process was painless and we are getting our new system on this Tuesday. Also got our heat back going for now and also gave us heaters until our new one goes in. Very friendly and professional service today. Definitely will recommend them.


Highly recommend!!! Amazing service, quality repairs and great staff. My Heating and A/C service provider from now on. We were so impressed that I had to call back and let them know. Thanks again to the GSM team!


I've been impressed with the professionalism of GSM advisors and technicians. Jim has gone above and beyond to make sure we're happy with the results and the systems are working properly. It's obvious that customer satisfaction is a real priority for GSM.

GSM replaced our broken AC unit and corrected problems with a furnace installation (which had been done by a different company through a home warranty). They also insulated and sealed our attic. We're signed up for regular seasonal tune-ups on the furnaces and AC units through GSM.

The only issue I encountered was that sometimes phone calls weren't returned promptly, so at times I had to call more than once to follow up on things. However, I'd still give 5 stars, because this was only a minor concern.

Oil Furnace Replaced With High Efficiency Heat Pump, Gas Furnace and Air Conditioning System

http://www.drenergysaver.com | 1-888-225-6260

A 70-year-old house with an old inefficient oil furnace, receives a full heating and cooling system upgrade. Dr. Energy Saver replaced the old furnace and High Efficiency Heat Pump with a backup High Efficiency Propane Gas Furnace and High Efficiency Air Conditioning System. High efficiency HVAC systems, by definition, are systems that give you the best results in terms of heating and cooling, per each dollar spent to run the unit. A heat pump works by bringing heat from the outside to the inside. It will produce $3 worth of heat per each dollar spent in electricity. When the temperature outside is below 35 degrees, the backup propane gas furnace kicks in, operating at 96% efficiency. High efficiency air conditioning/heat pump systems have a much bigger condenser and a higher SEER - Seasonal Energy Efficiency Rating- which is an efficiency measure for HVAC units.
