Mitchell and his Dad came to my house last week to add a return air duct and a humidifier to our…read morefurnace. Mitchell was very knowledgeable and I couldn't have been happier with everything he did. It started with the moment that I saw they wore booties when they came in my house, and took them off before they went outside. (Unfortunately, so many people think it is okay to wear booties outside and then come back in your house ~ not sure what they are thinking)? Mitchell did a wonderful job on everything and he and his Dad were incredibly neat. There was no sign of them doing any work. Everything had been cleaned vacuumed perfectly. I highly recommend Knock Knock for any HVAC work you need to have done. I don't say that easily. My husband owns a remodeling company and I have seen many shady people in this industry. Mitchell truly stands out and is a very genuine person.

Knowledgeable and fast! Up and running in just a couple hours! Top notch company with friendly technicians! So glad I found these guys. They also installed my main breaker box a year ago.

First I will say they didn't do any work for me. The guy that came out was nice, on time and really…read moreseemed to know what he was doing. They quoted me $1700 for the job I wanted done, which was way more than I was expecting. I was starting to YouTube how to do it myself! So glad I had another quote because he was also great, showed up on time and knew what he was doing. He was independent and had 12 years experience. He did the job for $480. I was very happy with his work and I can't see that the results would have been any different had I paid $1700. I guess the difference is that he doesn't have to pay all the overhead or middlemen for receptionists, fancy billing, etc. oh yeah, I'm entitled to write a review based on any part of my experience with the company. Now I'm even more happy that I didn't spend my money to support this guy. So make sure you always get a few quotes!

I contacted Birkley despite the previous one-star review (after all, if you don't like a company,…read moreyou don't continue to use them for 2 years). I was not disappointed. Joe, my service technician, arrived right at 9:30 a.m., the front end of his estimated time frame of 9:30 to 10 a.m. (He could give my cable guy a lesson in timeliness!) Joe was courteous, and went right to work. He didn't try to up-sale me on any "premium services" like other companies I have used. He also didn't try to sell me parts I didn't need - like the last company that serviced my HVAC unit. At the end of my appointment, all I needed was a new air filter. Joe thanked me, talked about his family business, and hurried on his way with a handshake and a smile. I will definitely be calling Birkley for my next service appointment!

Over the weekend while out of town on business, my heating unit stopped working. My Nest thermostat…read morewas set to 62F and when I returned, my house was a chilly 54F. Not good, I thought. After doing some basic troubleshooting - making sure the connections were fine and then swapping out Nest for my old thermostat, and seeing no improvement, I called for Birkley. They were able to come out to the house within a few hours, and gave me a courtesy call of 15 minutes prior to arrival so I could drive home. The technician went downstairs to do some troubleshooting, and while he was at it, he checked out the heating unit from top-to-bottom and gave it a good cleaning. Long story short, it ended up being that the neighbor had blocked the input/output pipes that led to the HE furnace. Once those were removed, the heating unit worked fine and now I have heat! Great, professional service. Allowed me to be inquisitive and showed me some of the workings of the furnace. At least now I know how some of it works!

We were in need of a new water heater and came across this company during a Google search. We were…read moresurprised that this company puts their prices on their website. Other companies want to come out and quote you. We stopped by Home Depot and they quoted us a price $200 more, and we never heard from them again. Since Just Water Heaters is BBB accredited with an A+ rating, and their Google reviews are 5.0, we decided to give them a try. Dale, the owner, answered the phone and promised to come out the next day. He confirmed the price that is listed on his website and kept us posted when we could expect him to arrive. He was professional and the work is great. We highly recommend Just Water Heaters.

I have an older ~1910 home, and we have had some serious challenges keeping the 3rd floor properly…read moreheated and cooled. Our third floor had been finished but not insulated, resulting in some very steep energy bills in the summer and winter, not to mention many sweaty/frigid days. Lewis was very patient with me as I explored my options, made some very helpful recommendations for other projects around the house, and provided the most reasonable price. He provided plenty of details about what his team would do without being overwhelming, and answered all questions I had. The team was in and out in less than a day, with very minimal modifications made (just a few access holes cut out), and were very professional in their work. Just with adding insulation on the 3rd floor, the entire house feels much more regulated temperature-wise, and I'm sure the energy bills will reflect the upgrades very soon. I will certainly be reaching out to them again for future insulation and energy-saving projects.

I was directed to this company from Duke Energy. I had been needing to get insulation added into my…read moreattic for a while now. My house was built in the 1950's and the insulation in the attic must have been the original. It was barely there. This company came in and did an assessment that was both thorough and quick. I was walked through everything that was recommended and was sent a quote via e-mail. The company does give you a discount if you sign the estimate within 10 days. I knew this project was desperately needed, so I signed immediately since the price was great. I have had several companies come into my home a few years ago with quotes that were significantly higher than what I was quoted by Sustainergy in October 2021. On install day, there were 2 workers who came in and worked very quickly to get the job done. They asked permission before completing a lot of the tasks (like opening a window, etc.). Very appreciative of the service! Both worked at my two separate attic entrances quite effectively and about half way through mentioned that my bathroom ventilation was damaged. They were able to call in and add it to my invoice and repair it right away! Loved that! They had protective barriers laid out to protect the floors. However, there was a bit of a dust layer left over on all my furniture after they left (to be expected), but it cleaned up easily with the vacuum and soap/water. As of December 13, 2021, over a month since the install - my house has definitely retained the heat and my furnace does not run nearly as much! My November bill was $60 less than it was last year! Thank you!!! Highly recommend!

No comment on the quality of their work, they were difficult to hire.

I was stressed and overwhelmed with all of the back and forth. I contacted Roger, he told me he would be out "tomorrow between jobs". He showed up on time, fixed the short-term issue in 2 hours, and told me the long-term repairs needed- said he would send over a quote for the recommended items in the next day or so.

Thanks again for all of the help.
