"What a fantastic experience with the folks from Greenlink! Need more than 5 stars to show how well these fellows did on our attic insulation project. Noah came out a number of times to go over what I wanted and was very knowledgeable and kind to me to answer all my questions. The first day 4 of Greenlinks team came out and started in to remove all the old nasty insulation and reviewed and prepped the attic in the garage. Second day we had 4 more come out and added the fan in the bathroom and sealed the attic in the house. Now the temp outside was really nice during these 2 days. However it was around 110 to 120 degrees in these attics and the crew was up there doing the work completing all the needed sealing and fixes. Many people may not understand how much work and effort goes into a job like this but I use to do some of this many years ago and I know how tough this can be on a soul. These fellows spent a lot of time in the attics and when it comes to adding the blow-in insulation that's the grittiest part of the job. These guys were fantastic, zero complaining and actually were enjoying what they were doing! The crew chief for both days was Kevin and he knew what was needed to be done and who and what order things needed to be completed and keep the guys busy. Everyone of these guys was a joy to be around and would answer any and all of my questions. Honestly one of the very best crews I've ever been around. Once they were done they did a great job cleaning up and thanked me for the business. I wanted to thank Kevin, Jaylin, Carl, Calvin, Al, James, Noah, and CJ that we will now be much more comfortable going forward. And to thank that young gal in the office Olivia for standing outside the building to help this old guy find the office since I got lost. What a great bunch of people and a great job they did here, well done. Rick S. Rockford, IL."

"This company raises the bar for customer service! I hired them to clean my ductwork and my dryer vent. Dillon explained everything that was going to happen - so I felt that I knew what the plan was. He is a wonderful ambassador for the company! Both he and Steven were hard workers who efficiently got their jobs done. Every time they came into the house, they removed their shoes (even though I told them they didn t need to). Very nice! The prices were very reasonable and the before and after photos showed me the quality of their work. And the scheduling process was easy, with a reminder call the day before and a call when the technicians were on the way. I m very pleased with this crew and this company."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

Heating and Air Conditioning questions, answered by experts

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.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.
