Case Studies From Gastonia
Challenge

One of our longtime residential customers came to us with a roofing problem in which they didn’t know who or where to turn to. There were rotten wood and post on the flat roof of their covered porch.

Job Stories From Gastonia, NC
Heating and Cooling System Replacement in Gastonia, NC

Complete system installed for customers home comfort.

Mrs. Laws noticed that her system was not running as efficient and consistent as it should. She gave GSM a call as we were her Heating & Cooling maintenance service of choice. Our Appointment Center team member Bailey set up a call for Kelly to visit her home to give her a proper diagnostic and recommendation for improvements.

The best choice that fit the customers needs and budget was the GSM TruComfort Signature Series 96% Efficient heating unit paired with the GSM TruComfort Signature Series air conditioning 14 SEER unit. We also provided the customer with new properly functioning low level CO monitor and a new Honeywell programmable thermostat.

This choice was the best fit for the customers home to improve their comfort, efficiency, and lower energy costs.

Air Seal and Insulate

Help make your house more comfortable and efficient!

On this job we completed our traditional air seal and insulate of the attic and air sealed the crawlspace as well. We installed SilverGlo to the attic-adjacent wall and sealed off the cavity as well.

Super deck install to provide a storage platform in the attic. Duct Encapsulation with spray foam to keep everything sealed and air tight.

Finally, we installed the stair hatch cover which keeps the air consistent, ensuring no air loss.


SuperHero Award

We have quite the honor to present to our very own, Scott Konowinski!

Story:

A customer called GSM Services to take a look at where bees are getting into the attic and see if we could spray foam the area to seal off the home. What’s more, the customer was on a HUGE time crunch for a graduation party being held at their home.

We had a Comfort Advisor go to the home to check out the situation and found out that the bees have been developing a giant hive behind the siding.

The homeowner wanted to remove the bees in a humane way so reached out to a bee-keeper, but that didn’t stop us from helping the customer.

GSM Services RoofShield division came into the situation to help, this is where Scott Konowinski “bee-came” a GSM Super Hero. We had various GSM co-workers involved in this job but Scott stepped up and volunteered to help remove the bees by climbing up on the roof in a bee suit.

After removing the siding, they found over 200 POUNDS of honey combs between the siding and the wall of the home.

Realizing that this was not a heating and cooling, home energy solution problem or even a roofing matter, our employees didn’t stop at their hired responsibilities.

This is a perfect example how GSM’s core values.

Core Value #3: Exceed customer's expectations in everything we do.

We are proud of the work that Scott provided so this SUPERHERO award goes to you!
