Thermostat Installation and Programming

I recommend Willy for Water Heater replacement and repair work!! He is hard working professional with pleasant personality. My tankless water heater needed repair. Willy talked to manufacturer on my behalf to get parts under warranty for free. He then installed broken heat exchanger which is no small feat since it requires overhauling the whole unit, replacing almost all major parts.

“Chilly Willy” replaced my aging HVAC system. This required relocating the outdoor, pouring a cement pad, changing to a smart thermostat, modifying the air handler connections to the existing ductwork and installing wiring from the electrical panel to the air handler. As surprises were encountered he approached each issue with a never surrender attitude until the job was finished. It was appreciated to be continually updated on issues and resolutions plus being on site as promised. I would feel secure recommending Chilly Willy to friends and family.

Great folks to deal with. Professional crew, install went great. Will use again if needed Highly recommend them for any HVAC work.

Most up to date technology. Guy can fix any problem quickly usually has parts on truck with him. He also does installs with new homes. He is hands down the guy you want to working in your home treats you like family and knows every brand in and out. Wouldn’t use anyone else.

Exceptional experience with Chilly Willy Mechanical Services. Will was prepared and able to handle all new-homeowner requests I threw at him. From hanging complicated light fixtures, to figuring out the noise on the AC unit - he showed a wide range of skills. I’m thankful to have his contact information handy when in need of home services. Thank you, Chilly Willy!

I’m using chilly for both business and personal hvac needs . Outstanding work with a great attention to detail . And a pleasure to work with !

Awesome job, very respectful, did great work an very professional… Highly recommended!! RGX TN you must just be a hater trying to give people bad reviews post a review with your name on it not just some letters this guy is a hard worker!!!

Second time I’ve had to call for some help with my older AC unit. Will comes by same day and gives me a fair and honest service. Will use them when it’s finally time to replace the system. Would recommend!

He is a very hard worker!!! Would highly recommend him!!! Wonderful company!!!

Fantastic job!! If you need help with HVAC or any of his services this is the guy to call. Fixed my A/C and installed a hot water heater for me and my family. If you need something fixed more importantly fixed right this is the guy to do it.

My husband and I woke up on a peaceful saturday morning and enjoyed our morning coffee like normal when suddenly we hear what sounded like a super loud lawn mower right outside our back door. Suddenly our hvac system stopped. My husband being a mechanic walked outside and tried a few things that he knew of and called a few buddies that he knew but couldnt get anywhere with it. Right then he knew we had to call a professional. We called several companies and nobody wanted to come out on a Saturday apparently. When my husband called Will he immediately said "Man I can be there in an hour to take a look". He showed up about an hour and a half later. (our house is a little complicated to find) Our issue wasnt very straight forward at all.. After 7 very tiresome hours he was finally able to find the issue. Excuse me but I am not very smart when it comes to this stuff but I believe a wire had burnt somewhere inside the house but it was almost 9pm when Will finally found the issue. However he never gave up even when he seemed stomped he got on his phone and called a friend for some advice to figure out the issue was somewhere inside the house rather than outside. We bought this house 5 years ago and was told by the seller that the ac system had been replaced in 2018... after Will checked into things and saw the date on the unit itself it was quickly determined that the unit was a 1999 unit.. And the best thing to do at this point was replace the entire system. Wills prices LITERALLY beat everyone elses. This man not only came in the cheapest, he stayed in touch about arrival of the unit, worked tirelessly, several nights til late in the evening to make sure my family wasnt left uncomfortable in the heat for too many days and even fixed duct work that had been messed up for years. I highly recommend using Will for any HVAC needs. I know me and my family are extremely grateful and will continue to use him and spread his name for many years to come!

Working with this company has been an excellent experience. Initially they came out to diagnose why my old system was off and had me back on with heat that night. The system was back off the next morning but not due to them. It was old and I already knew not long for the world. Will quickly sent me several very reasonable quotes for a completely new system, and installed it in the evenings when I was home from work rather than needing me to take days off from work. He has contacted me several times since doing the work to make sure I'm the whole system is operating well. We have all new duct work as well which is wonderful, especially after seeing the inside of the old system. I will continue to use this company to service and maintain the system. Both Will, the owner, and all of his guys were incredibly respectful of our space and left the property better than they found it hauling out all of the trash from the job as well as some other things they found in the way the previous owner left. This is a great company to work with, I am glad I found them through their previous Google reviews.

I recently worked with Will on an installation project. He was punctual, communicative, and reasonable. Will and his team worked diligently all evening to complete the job. Thanks to their efforts, my garage is now nice and cool. Don’t be silly, call Chilli Willi!

From the beginning Chilly Willy Mechanical LLC was outstanding. Customer service and knowledge of the product stood out from the rest. Replacement of our HVAC unit was a first for us. Instillation and finished product look amazing. I will highly recommend Chilly Willy Mechanical LLC to everyone.

Will has been my go-to for all HVAC questions for years, even before Chilly Willy was founded. He’s unbelievably knowledgeable, more than fair cost wise, and just gets the job done. It can be difficult to find trustworthy contractors and Will is the best of the best.

What a great experience I had with Chilly Willy Mechanical Services. Will was very professional, extremely knowledgeable, and thorough. He installed a new HVAC system in one of my rentals. Provided good advice and followed up. I will trust my routine maintenance and service needs to CWMS.

Our outside HVAC unit went bad on 1/15/24. I had recommendations to call Chilly Willy Mechanical LLC, He came down and gave me a better price than any other HVAC Company. He put a new Trane inside and out, as well as new lines, wires and thermostat. My wife and I are very well pleased. He explained how to use the new equipment and called twice to make sure all is working well and to see if we were satisfied. He did a great job and I wouldn't call anyone else. We highly recommend him. He was very polite, friendly, and professional. David and Lynne

I highly recommend Chilly Willy services. He was prompt, courteous, and knowledgeable of our HVAC situation. Most importantly, he offered practical and affordable solutions that the big corporate companies often overlook, saving us time and money. Added bonus: He drives a super cool truck

Exceptional experience with Willy. It’s very obvious he has decades of knowledge in the HVAC and plumbing trade, both commercial and residential. Usually with that type of experience you pay a premium, but his rates are some of the most affordable in the greater Charlottesville/Fluvanna area. If only all contractors were like Chilly Willy… TOP NOTCH!

Great service and emergency response. Very affordable and easy to work with. I would highly recommend him to anyone.

They responded, they showed up when they said they said they would and they did good work, all while being friendly and honest. You can’t ask for much more than that.

Great communication and service. Thanks!!

I call Willy at 4pm advise him we had no heat (with an outside temperature of 25 degrees). He arrived on time, quickly diagnosed the problem and made the necessary repairs. While looking over the unit Willy discovered the emergency heat was not functioning properly. After few minutes Willy had the emergency heat working. I would highly recommend Chilly Willy

Chilly Willy worked long hours when our heat pump went out to get us back up and running. Very professional, clean and tidy! Would definitely use again and recommend to friends and family!

Will came to by rental property at 6PM on a weekend to install a failed(failing) thermostat. His prompt response and ability to quickly diagnose the problem left me satisfied. My tenant especially! Thanks Will for your prompt response!

I have used Will Mayo to install a new AC unit in my house. He was courteous, neat and professional. His quote was reasonable compared to other HVAC quotes. I would highly recommend him for your project

Thank you for the dedicated and awesome work. With the hot weather and a bad part, William was only available to drop by at 9:30 pm for an emergency fix, he had to troubleshoot and temp fix until the part was installed the next day. Excellent job and a very nice guy who got the job done! Thanks Aj

I feel very fortunate to have found an individual as passionate and hard working as Will for something as mundane and foreign to me as HVAC. I was very nervous going in because I knew so little about HVAC. From the start Will came off as straight shooter that could be trusted. He was very good at explaining the scope of work involved, something I did not get from other companies! He was great about answering questions and it felt like he was excited to explain things. The full system replacement he did for us was exceptional; the new unit was installed with great care and neatness. It goes beyond that, though. While he was giving me an estimate, he looked at my sump pump and asked me a few questions about it. Basically the water level looked high and he wanted to make sure it was working. So this guy spends like 15 minutes trying to get this thing to trigger. I feel like for most that would be an "eh not worth the trouble at this point" when I insisted to not worry about it when he had to go to his truck but he insisted. He had to get a special bit to open the cover so we could add water. It was just the most above and beyond experience I've had with a skilled tradesman. It was just somebody being a good person. With 10+ years of experience you can't go wrong with Will. His communication was solid, his pricing was more competitive than other large HVAC companies, and it was a painless process. Might have been two weeks from estimate to the installation being done. This is a business I definitely recommend to others!

Chilly Willy is the man I’ve bought a 1998 single wide and the HVAC system had been badly abused he showed up in a very timely matter and cleaned my neglected ‘98 HVAC system photos are before he cleaned parts in my unit but it’s blowing really strong and quiet plus has it cooling really well, like his saying says “don’t be silly call Willy” thanks Willy

Fast, fair, thorough, incredibly knowledgeable and a straight shooter. Gets it done when others couldn't. Quite possibly heroic, depending on your circumstances, as he takes calls later than most regular business hours. He's the gold standard for mechanical services in Central Virginia, as far as my restaurant is concerned.

Kate in the evening my AC went out I called Mr Mayo came right out checked my unit out found the issues out a universal part in that he had on his truck until my part came in came back the next evening and switched parts out not a bit if issues since didn’t over sell me and didn’t charge me a fraction of the other so called Bug companies was going to charge me He will be my first call the next time I need any work done
