Greenlink Energy Solutions is a locally owned and operated business. We specialize in home performance including but not limited to Insulation and audits. We will provide you with the same great quality work that has kept us in business for years because we feel that our customers come first. While this is not a new concept, it seems to be one that a lot of contractors have forgotten. Our focus is to provide your home, business, or building the most efficient and green solutions for your home. We guarantee quality work that provides the best results which means decreased utility bills, higher level of comfort, eliminating drafts, and ensuring your home is at peak performance. We provide solutions for every aspect of a home: HVAC, Ventilation, Insulation in all areas, Windows, Doors, and Solar Panels and Renewable Energy.

"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."

"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager. Said he would follow up, I never heard from him. Blessing to me, I decided to go with another HVAC company. I typically would not put names out there, but please be careful if you get this gentleman as a technician."

Heating and air conditioning services FAQs

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
