AC went out on Tuesday. Had another company that we've used in the past come out on Thursday and…read moredetermine it was the evaporator coil needing replaced. So decided to check around on timing and pricing after doing some research on the internet. I submitted a request for estimates on HomeAdvisor and Yelp, describing the repair needed. KTS reached out to give an estimate, where many did not, and I called John on Friday and told him the situation. He gave an estimate in range with what internet suggested for Chicago area and said he could come out Sunday morning. He came out early Sunday morning, verified the problem and replaced the coil efficiently and cleanly. Cost was in line with the estimate he provided. Very happy to have the AC going again and will use them again for any other heating cooling needs.

He was professional and arrived on time. However, when I got a quote to install a Nest thermostat it was $200 for maybe 20 minutes of work. I got a quote (attached) for Aprilaire 500 bypass Humidifier installed to replace an existing one that's failing and I was told the unit is worth $600 and it would be $1170.00 to install (which included a 5% discount if I bought a service agreement with them). I said it seemed a little high so I got more quotes. So far two reputable places quoted $550 and $425 installed and the unit is $230 at most online. Update: so my Aprilaire 500 humidifier was installed by Green Air Care and everything was great with them (see review). They even fixed a couple quirks with my system. Per Brian's Heating & A/C's request I did call Brian's to see why their quotes were so high but they were unavailable so I asked for an email response. If their response email makes sense this may be updated but $600-900 an hour for labor seems really high to me. As with all large projects I'd recommend getting multiple quotes if time allows but the quotes I received from this business were a little outrageous in my opinion.

They came out twice to review the job to figure out the right way to install the internal parts so the two units would be in the ceiling. It was incredible how they did this.

We had a small issue afterwords, but they came back and corrected it with absolutely no problem. I HIGHLY recommend this company for any HVAC work needed.

I wonder why... 2. For those who want to try him, here is the summary, FYI: He posed as a legit company, and we believed and hired him to install our furnace and a/c 3 years ago in the late fall, but a) he charged us $400 more than quoted, and b) he did not charge the cooling agent in the a/c, promised to come back and adjust and charge it in the spring, but he never came back and stopped answering the phone, and I had to hire a dif. HVAC guy to charge the coolant. 3. Later on, it turned out he violated the fire and building code by installing a flexible gas hose to the furnace instead of solid metal drip leg for moisture and debris (to protect the gas line), and I have to hire a dif. HVAC company to do that too. 4. He is not a registered installer with any HVAC manufacturer, like Carrier, Trane, Lennox, etc.

He took the time to thoroughly explain the issue and walk me through the solution, making sure I felt confident and informed every step of the way. What really stood out was his attention to detail and commitment to doing the job right--not just quickly, but correctly. His HVAC knowledge is second to none, and it truly shows in his work. If you're in Carol Stream and need honest, reliable HVAC service, I highly recommend Giovanni and the team at Grays Mechanical!

My AC stopped working on a hot and humid day, and I initially assumed it was a complex issue like a…read moreleak, which felt beyond my ability to fix myself, so I called a professional. I was incredibly impressed by how quickly Affordable HVAC responded, with a technician arriving within 30 minutes. The technician was on-site for about 45 minutes total, seemed knowledgeable, and checked the pressure in addition to diagnosing the problem. He identified a swollen capacitor, a clear sign of failure. I was a bit confused during the diagnosis, as I had observed my unit turning on and blowing marginally cold air before his arrival, and he stated a bad capacitor would prevent the unit from turning on at all; perhaps there was a misunderstanding or a communication gap regarding the nuanced stages of capacitor failure, or it failed completely just prior to his check. He then proceeded to efficiently replace the capacitor very quickly, getting my AC up and running in about 15 minutes. Before starting the work, I was quoted $420, which I agreed to at the time. In the literal heat of the moment (it was 85 degrees!), I blame myself for not voicing my concern about the price and simply wanting my AC fixed. After the repair was complete and he was preparing the bill, he asked if I would be leaving a review. When I said yes, he offered a discount, bringing the total down to $390. While I'm very happy my AC is fixed and truly appreciate the fast, effective service, I do feel that the final cost of $390 was quite high for such a straightforward and quick capacitor replacement. As someone who is handy and has even tackled much harder DIY projects (like replacing an entire sump pump last year), and later learned the part itself costs around $30 locally, I couldn't help but feel the price was on the steeper side for this specific fix. Frankly, if the total had been closer to $290, I honestly wouldn't be having this buyer's remorse, and it truly would have been a 5-star experience. The irony of the company name, 'Affordable HVAC,' was certainly not lost on me given the cost. Ultimately, you live and learn.

My husband and I are so thankful that John was recommended to us. Two of my coworkers (one teaches…read moreHVAC classes!) both gave such positive remarks about the work that John has done for them. Since my husband and I recently bought our first house, I wanted to make sure that our furnace was prepared for our first winter in there. John was extremely pleasant over the phone, and he arrived within 15 minutes of the 1-hour window that he gave us. When you plan your day around someone being over at a certain time, it is wonderful that they actually show up when they say they will! John took the time to explain everything he was doing. His motto is "an informed customer is a happy customer" and I could not agree more. He replaced our furnace humidifier filter - which I didn't even know we had one! He checked what our humidity levels were at (found out they were too high). He gave great recommendations for products, as well as super helpful maintenance advice on everything furnace-related. He uses excellent quality products and charges a very fair price. We will absolutely be calling him in the spring for our AC tune-up. I wish he offered more services so that we could get his expertise all around our home! We're so thankful and relieved that we found someone who is local, experienced, honest and trustworthy! We could not ask for a better person or company!
