“I feel very blessed to have found an amazing HVAC company that I will use again and again! Below is my step by step experience with Smith & Sons Heating and Air Inc. Scheduling was easy. Rescheduling because I lost track of a medical appointment two days prior (on a Saturday) was also easy and very pleasant. There was no fuss about the short timeframe before the original appointment (Monday), just prompt customer service and were able to schedule me for the day after my original appointment on Tuesday. Kyle came to my house and was very polite and professional. He had booties to wear inside as to not track through my house, which my wife and I appreciated very much. I do not know much about HVACs, but Kyle was thorough, taking pictures of every measurement (heat and A/C temps at the vent, temp at the intake vent, measurements on the HVAC system in my attic, and condenser/fan outside) so he could show and explain to me any outliers outside of the normal range. The only outliers I had were on my capacitor on the condenser/fan unit that is outside. He took the time to explain to me what role a capacitor has in the HVAC system and when it underperforms, it stresses the fan motor and condenser. It was performing at 58% and 20ish% (I did the math, what can I say, I am a nerd sometimes lol) of what it should have been for the condenser and fan motors, respectively. Very important: He was not pushy whatsoever about the replacement. He simply offered a quote for the part and labor, and said he would be able to do it on the spot. No pressure, which I very much appreciated. I opted to have Kyle replace the capacitor, as it is much cheaper than replacing a fan motor or condenser, which he was able to do very quickly. As a new homeowner, I have discovered that I need to have a go-to company for certain items outside of my ability to do on my own, which I have gained considerable handy-man skills in the last five years as it is much cheaper to do work myself. I am very glad to have my go-to HVAC company as Smith & Sons Heating and Air Inc! P.S. Military friendly company!”

“After dealing with several HVAC companies, Guthrie & Sons clearly stood out as the most ethical, honest, and reliable. From the very beginning, their approach felt transparent and genuinely focused on what was best for us—not on upselling or unnecessary replacements. We worked with Vlad T., who had previously been out to our home and saved us tens of thousands of dollars by getting our existing AC unit up and running when other companies were pushing for a full replacement. That experience alone earned our trust. Now that we’re finally ready to purchase new units, there was no question that Guthrie & Sons was the only company we would consider, and Vlad was the obvious choice. He was extremely professional, punctual, and exceptionally knowledgeable, taking the time to explain options clearly and thoroughly. His expertise and honesty made the entire process straightforward and stress-free. If you’re looking for an HVAC company you can truly trust—one that values integrity, quality workmanship, and customer service—I cannot recommend Guthrie & Sons and Vlad T. highly enough. This is how service should be done.”
