"We recently replaced our Heating & Cooling system with a energy efficient furnace & air-conditioning unit. We knew what we wanted, so I received bids from 4 different suppliers, receiving bids for a apples to apples comparison. All-Temp was by far the best pricing. Our installation process went flawlessly & the installers answered any question that I had. They came back out to our home per my request on a couple more occasions, to adjust the amount of time the 2 stage system ran. Everyone that we have dealt with has been extremely professional, courteous & knowledgeable. We just received a clean & check of our system & Jen our technician met each of those attributes. I would highly recommend All-Temp for any of your heating or cooling needs. Herb Pitzman Huntley, IL"

"I was extremely grateful that they had a technician scheduled for other stops in my area the day I reached out on Angi, and that they were able to fit me in that day to repair my broken central air conditioning. Everyone in our house is very glad to no longer be sweltering in the heat."

"Hired to clean my dryer vent. I will say the tech who showed up was very nice and he even took his shoes off when he came in. He cleaned my vent from the outside in (which I thought was strange) because I was told he would do this**the technician will disconnect the vent from the dryer machine itself , and then from the inside-out he will clean the vent from lint and everything inside with specially designed equipment only for the dryer vent. If possible he will clean the outside of the vent as well ( If it is not too high in the air exit )** So he actually didn't disconnect the dryer from the inside first, he actually had it turned on while he cleaned it from the outside. 1. I could hear it running and 2. I could hear the alert it makes when it turns off). I could see everything blowing out and all over the place outside, also I heard a loud noise but then nothing so I figured it was just part of cleaning, about 10 minutes later the tech calls me downstairs, the dryer is now disconnected and he told me he found all these broken plastics pieces just inside the vent where the dryer connects. He has no Idea at all what happened or what the pieces are. I go upstairs and google and it looks like the blower wheel broke apart. The tech now reconnects the dryer and turns it on and it makes a loud noise, He says "maybe it's unbalanced" I mean really??! I mean maybe the piece would have broke anyway (dryer 8 years old) but at the very least admit it happened. He had the dryer on previously while he was cleaning and it sounded fine. So anyway I pay him because he did clean the vent, I want to pay CC , he suggests venmo, I say cc is fine , he says he'll have to charge me a percentage for fees, I told him I didn't care, so he goes to put thru card then all of a sudden says he just got a text and the system is down so I have to pay another way...Ok..LOL. So he leaves and I looks outside and there was Lint everywhere! I told him he didn't need to go crazy picking up every piece but he didn't pick up anything, All over my bushes, grass, blew up to my deck. The more I thought about it I decided to email the company with pictures, told I would hear back Tuesday. They wanted to send the tech back so I could explain what he didn't do?? then they gave me this explanation**** *** Technician said that he cleaned your dryer vent from both sides. From the inside - out and from the outside - in. When he touched the hose from the inside out , he found plastic pieces inside of the vent, which he reported right away to you . He believes that those pieces were from a dryer blower ( plastic blowers are rare and this probably means that it needs to be changed ) . Those pieces were already there , generally he doesn't touch the machine itself at all which means he couldn't cause those pieces to be there. As for the mess, he says that he picked up like 95% of it , but because it is kinda picky small stuff and the dryer vent was clogged a lot, so the smaller portion of it was probably blown by the wind around the bushes . He says also that you have seen him how he looked after that and he told you that because of that clogness the blower was putting too much force and probably got overheated and that caused those broken plastic pieces. That is what he said , if you want to have a word directly with him please let us know, or suggest what we should do. Thank you.**** I mean the plastic pieces were already there?? he cleaned up 95 percent?? and I'm the one who told the tech what I thought the pieces were!?? Honestly a manager/owner should take responsibility for his employees and not go back and forth with a customer. Also they state they are BBB accredited and they are not. I advise people to look elsewhere."

"Austin, Orin and James were great to work with. Due to raccoon damage to the attic insulation and ceiling drywall all old insulation needed to be removed and contaminated areas treated. They installed new soffit baffles between each pair of rafters, sealed all potential air leakage points (e.g. around can light fixtures), ran all new insulated bath fan ducts (4) to soffit mounted valved vents and blew in all new insulation. Cost was very reasonable. Overall excellent value. Austin provided my insurance company with all necessary information so the claim was quickly settled to my satisfaction. Highly recommend Greenlink Energy Solutions."

Air Conditioning questions, answered by experts

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.
