When it comes to heating and cooling services, your home deserves the best. For over 30 years, Gagne has helped Georgia residents survive unpredictable weather by providing exemplary HVAC services, from air conditioning installations to heating repairs. Here’s a deeper look at some of the services we provide.

Air Conditioning Installation & Repair

Every home needs a proper air conditioning system — especially those located in warm areas like Johns Creek, GA. To combat the high summer temperatures, our HVAC company will assist with air conditioning installations and perform any air conditioning repairs on your existing system. Our services include:

  • Selecting evaporator coils and fan coils
  • Installing humidifiers to control moisture
  • Installing ventilators to enhance air quality
  • Integrating heat pumps with your AC system
  • Executing regular air conditioning maintenance

Our team will also install high-tech thermostats, such as the Infinity Control touch screen thermostat, that can be used to quickly and easily adjust temperatures and improve air quality.

Heating Installation & Repair

With temperatures dropping down to 30 degrees Fahrenheit and lower, it’s important for Johns Creek residents to have adequate heating systems in their homes. In addition to heating installation, Gagne offers heating repairs to solve any number of problems, from a malfunctioning ignition control to an improperly functioning belt. We also provide regular heating maintenance, which can:

  • Extend the lifespan of a heating system
  • Reduce costs by eliminating the need for larger repairs
  • Preserve the air quality of your home

In the unfortunate incident that a unit cannot be fixed through heating repairs, our HVAC company will work with you to find a new system that meets your needs and properly heats your home.

Mini-Split Services

Does one room or portion of your home tends to heat or cool more quickly than others? Do you often get into arguments over the thermostat with family members? Our mini-split systems solve both of these problems by letting you control the temperature of each room separately. Moreover, if you have a room-specific problem, having a mini-split system eliminates the need to get your entire central system duct fixed. For example, if your living room is not cooling properly, our air conditioning repair specialists can service the mini-split  system in that room alone, helping you save on costs. 

Heat Pump Services

As climate change continues to pose a threat, more and more homeowners are searching for energy-efficient alternatives. As part of our heat pump services, we sell and install Carrier Hybrid Heat Systems that conserve energy and save money in the long run. Your energy bill is in part determined by your Heating Seasonal Performance (HSPF) during the winter and your Seasonal Energy Efficiency Ratio (SEER) during the summer. By keeping your HSPF and SEER rates high, we keep your energy consumption low.

Commercial HVAC Services

Households are not the only locations with heating and cooling needs — our HVAC company offers commercial HVAC services for local Johns Creek businesses. We execute both air conditioning maintenance and heating maintenance on your HVAC system to promote longevity and quality. If we feel that your system is outdated or costing too much to operate, we will make recommendations and work with you to install the best HVAC system for your business.

“I had a great experience with our Gagne technician. He was on time, very knowledgeable and even went back up into my attic to help me label some vents when he was done and about to walk out the door which was really helpful! I’ve been using Gagne for years…always a good experience.”
