They took the time to answer my questions and made sure I understood the process. The installation itself went smoothly, and the quality of their work was excellent. Everything looks clean and works perfectly. On top of that, their pricing was very reasonable compared to other quotes I received.

I called 6 contractors to get some bids and the majority had a sales team that gave me the estimates, none are actual installers. Ian/Jason stands out because they actually came to my house, gave the estimate, and did the install themselves. No high pressure sales team and no technicians. Ian was very thorough on finding the right solutions for what I need, a rare quality nowadays for an honest contractor. On the day of the install, they came on time, completed the install, and cleaned up everything. I will be using Ian/Jason for all my HVAC needs and will be recommending them to friends and family.

Juan came with the sales pitch (i:e: if you agree to go with us now, we'll give you a discount...but only if you decide RIGHT now). I had to sit through a binder presentation and he told me I needed a new furnace to go with my air conditioner unit because the A/C condenser and furnace have to pair up for operational purposes and they won't replace one unit only if they are both more than 8 yrs old. He showed me some scary pictures of his furnace "inspection" and said my furnace was a fire risk, had evidence of decomposition and potential CO exposure and in the "interest of safety", he recommended a full system upgrade. The pictures were legit bad and concerning, but the funny thing is, the pictures he showed me were not the inside of my furnace. I had 4 other local vendors come after him and all of them showed me photos of inside my unit. Guess what? Their pics all matched each others and none matched Juan's pictures. Weird right? The other 4 local vendors inspected my furnace and all of them noticed the refurb of all the major components I had done 5 years ago. All said that no furnace replacement was indicated and my furnace was in great shape with many high functioning years left. Weird right? I intentionally never offered that info up to any vendor before the inspection as a secret test to see who would be an honest tradesman and who would not. See a pattern here folks? Juan's quotes came in at $17,500 for an electrical system (a/c and furnace) and $18,046 for a gas system (a/c and furnace), because you know...can't just replace the AC unit in his world. All other vendors (who have higher/better reviews on Yelp btw) came in between $8-10k for a new a/c unit. Again, all said no need for a new furnace. So, i'm counting my lucky stars I wasn't duped. Going with someone else and getting my new A/C unit installed tommorow

Last few years, the ac would sometimes turn on and going into this year, I didn't want to worry. I booked Smart on-line and it was really easy. Michael came by and he checked the current setup and explained what needed to be done to replace the unit. He was extremely knowledgeable and answered all my questions. Granted this was my 4th quote so I knew somethings. He never pressured me to purchase but i decided to pull the trigger to have him do the job. The rate was competitive but it was his knowledge and being personable that I made me feel comfortable to have him do the job. The replacement happened the following week and his team took all day. Michael went above and beyond making sure the job was done right and replaced a wood piece to my attic that he didn't need to do, but he did. Very nice. I talked to Susie at the office and she made sure I was aware of the next steps for the HERS test and city permit visit. She was personalable and said to call her or Michael with any questions.

To their credit, the company responded and offered a $50-60 credit, but given three other companies quoted the same repair at $450-$650 all-in, it's hard not to feel overcharged.
