Testimonials
What Our Clients Say?
Posted on Google Jeff Hanks I've had Nixon from Fireside Heating & Cooling over to our house twice in the last week (two separate issues) and he's been nothing but professional. He quickly identified the issue both times and either repaired or advised on the best course of action. Most importantly for me, he explained what was going on, how to prevent it in the feature and didn't try to scare us with "this is going to be a huge problem - you need to spend a large amount of money or replace your furnace and AC right now", like we so often here. He was very pragmatic in his approach and its clear he's trying to win customers the right way, through great customer service, transparency, and being fair.Posted on Google Mark Welle Jr. Nixon is awesome! He and his crew diagnosed and repaired my AC system when others thought it wasn't able to be fixed. He went out of his way to find out what as going on, educating me along the way, showing me his findings, and explaining what my options were, all with a friendly and knowledgeable style. He was able to quickly source the parts that were needed and made the repairs the next day. Nearly half the price of one of the other 'big brands' you see on TV. And Nixon is the absolute best guy overall to work with! You absolutely can't go wrong hiring Fireside Heating & Cooling for your repairs or even a new system. Had I needed a new system, which he NEVER tried to upsell me on, that too would have been $1000s less than others. No high pressure sales, no scare tactics, just an honest assessment and repairs at a fair price. What else could you ask for?!Posted on Google Jeff Cline Nixon was fantastic. Helped me through the whole process and answered every question and concern I had before even signing the contract.Posted on Google Jamie Wolff Fast and efficient, very polite, and friendly. He took the time to break everything down for me so I could fully understand what was going on with my system and where it had failed and why. I didn’t feel like I was being swindled, which was a nice change. A great experience overall.Posted on Google Corey Roberts Nixon was a straight shooter and gave me all my options. Never pressured us one way or another. Got a few quotes and his was most competitive on each option and never felt like there was any sacrifice in install quality or part quality. He fixed a lot of unrelated things on his dime to make sure we were best positioned, and best of all our cooling has significantly improved. Will recommend.Posted on Google Jeff Robbins All I can say is these guys rock! Replace one unit and air handler in 4 1/2 hours. The quote we received was thousands of dollars under the next lowest quote. Very respectful and will have my business moving forward.Posted on Google Mike Garcia Nixon was great. Communication was perfect. I knew immediately that he had skills. Everything was done to perfection. I recommend him and have already referred him to other people.Posted on Google Jennifer Morton Highly recommend! My AC is an older unit and I was worried I might need to replace it. They were able to diagnose the problem and repair it the same day. Nixon the technician was awesome! He was professional, honest and took the time to explain everything. Great experience!Posted on Google Tom Feeney Nixon and his team at Fireside heating and cooling did great work. Most importantly they communicated well and followed up to make sure all the work they did was completed to my satisfaction. They came in as the most affordable option between five quotes I took for my AC install. Thanks, NIxon.Posted on Google Annaliese Rutishauser Nixon did such an amazing job for us! He explained everything clearly and his price was completely fair. He was punctual, professional, and completed the job timely. We’re extremely happy we decided to go with him and will use him in the future.Load more
