"Mr. Carlson is a professional in every sense of the word. From a quick reply of my initial inquiry to detailing every step of the process, this gentleman provided a very accurate itinerary of how the repair would be conducted and did just that. Ultimately we now have a cool home and a very satisfied pair of customers that would highly recommend to employ this company to assist with their HVAC needs."

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

"In October of 2024 I had the most excellent good fortune to work with Greenlink Energy Solutions as part of an ComEd Home Energy Efficiency project that included replacement of the furnace/a.c. and water heater, as well as top to bottom weatherization of my house. Even before the project started both Olivia and Jarron took the time to answer any questions and address any concerns I had regarding the equipment being installed and the overall scope of the project. Day 1, first up was a couple of electrical guys, quickly followed by Jarron and his HVAC team, Ben & Ryan. All on time and ready to get to it. Professional, pleasant and remarkably tolerant of my nonstop questions about the systems, the guys went to work and, other than a quick lunch break, worked nonstop, not particularly concerned about the clock but more about getting to a reasonable stopping place for the day. By the time they were finished, everything was operational, square and plumb, all pipes, valves, duct work and conduit looking very slick, orderly and professional. (5 stars just on the sheet metal work alone). Next up was the weatherization team with Nick leading the charge. Again, on time and ready to go. These guys, Zarek, Steven and Danial, came in with a plan and went right two it, peeling off to address varying issues and again, once on the ground it was go time for these guys. Remarkably, all willing and ready to jump in to even the less desirable parts of the project (like who really wants to go into a hot attic and crawl around in the corners? But they did it and with no hesitation or whining). Over all there were several things that impressed me about the Greenlink teams. There is the obvious stuff, like the punctuality and, remarkably, the through cleanup at the end of each day, and also the obvious work ethic, mutual respect amongst the team members and easy and informative communication with me. I think what was the most reassuring though, you could see the obvious pride the Greenlink people take in their work and, just as importantly, the obvious pride they take in working as part of the Greenlink team. That says a lot. I would not hesitate to recommend Greenlink Energy Solutions to anyone. I suspect my neighbors are already tired of hearing about how good they are."

Heating and Air Conditioning questions, answered by experts

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.
