"Tyler knows HVAC systems. When he came to our service call, he was able to give recommendations and diagnose our problems. He did this very efficiently and explain things in a way that a non-HVAC person such as myself could understand. At the same time, he was able to explain things to my husband in terms that I am still trying to figure out. We are definitely getting a service contract with Laury as long as Tyler is the one who comes to our home!!"

"The specialist sent was amazing. He showed me everything step by step that was wrong with my HVAC. The house was constantly at 91 degrees and he fixed it all there and then. I had talked to many companies about the HVAC job I needed done. They all said they would â call me to schedule an appointmentâ but this gentleman reached out came within the hour showed me everything that was wrong. He fixed it all in well timely manner, he was clean, and very polite. He will give you the best prices. He is a hard worker and very knowledgeable. He will be maintaining my hvac system from now on. Would recommend 5/5"

"Excellent service. Got brand new HVAC units and had the coils replaced. They were thousands less than the other three bids. Came in laid drop cloth to make sure nothing would be tracked in. Very polite and quick and cleaned up when they finished. A++ Service will recommend and hire again."

"I hired GSM Services to replace my A/C unit and furnace with a newer, upgraded system. A few weeks ago Kelly came to my house to give me an estimate for a new heating and air system. He was on time and very professional. He surveyed my existing system, took measurements of my house, and did some calculations to determine exactly what type and capacity system that I would need. He showed and explained to me several options as well as their prices. He wasn’t pushy as he left in order to give me time to review the different options before making my decision. I called the office the next day with my decision and to set up a date and time for installation. Today (May 22) Kyle and Craig showed up on time and were extremely professional as well. They worked from 8:30 to 5:30 completing the replacement of my entire heating/air system. The field team leader also showed up just to ensure that everything was going smoothly. They were very helpful in answering any questions that I had throughput the day and they took the time to explain to me about the new system after installation was complete (I.e. how to operate the new programmable thermostat). Overall, it was a great experience and I will definitely use them again."

Heating and Air Conditioning FAQs, answered by experts

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.
