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.

Unfortunately, your response omits several important objective facts that I discussed with you…read moredirectly during our phone conversation. First, repeatedly referring to my furnace as "a 1996 furnace" is misleading. While the cabinet was originally installed in 1996, all major internal components were professionally replaced five years ago. Multiple licensed HVAC contractors immediately recognized the refurbishment during their inspections and all independently concluded that my furnace was in excellent operating condition with decades of service life remaining. More concerning was your technician's sales presentation. I was told my furnace was a fire hazard, posed a carbon monoxide risk, and required replacement in the interest of safety. Those are serious claims. Yet four independent licensed HVAC contractors disagreed with that assessment, and none recommended replacing the furnace. Instead, they all recommended replacing only the air conditioner. You also claim the photos your technician showed me were legitimate. That claim is difficult to reconcile with what I personally witnessed. I watched all four of the other contractors perform their inspections in real time. They each inserted their phones into my furnace, showed me live video from inside the unit, and provided photographs of the internal components. All four sets of images were consistent with one another. None resembled the photos your technician used to justify replacing my furnace. That discrepancy is exactly why I sought multiple independent opinions before making an $18,000 decision. During our phone call, I explained all of this to you and provided the context regarding the refurbishment. Your public response ignores those facts and instead repeatedly relies on the original installation date to justify the recommendation somehow. My review was never about whether homeowners can replace both systems at the same time. Many choose to do so. My concern was being told that I NEEDED to replace a recently refurbished, fully functional furnace because it was supposedly unsafe. After obtaining four independent opinions, I concluded that your recommendation was not supported by objective facts. "Facts don't care about your feelings" the saying goes. Prospective customers can draw their own conclusions. I certainly did, which is why I sought additional opinions before authorizing nearly $18,000 in work. That decision saved me thousands of dollars, a potential service install nightmare (see the numerous 1 star reviews by others) and I stand by my review.

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.

He patiently answered my questions, was willing to help whenever I had concerns, and never made me feel rushed. Everyone on the team was polite, respectful, and took great care to protect my home during the installation. It's refreshing to work with a contractor who truly cares about quality and customer satisfaction.
