Technician was able to arrive same day, repaired our A/C quickly. Our A/C is colder now than it has been since we bought our house 14 years ago. Because the experience was exceptional, we purchased a service plan.

This company is honest, value priced, and did excellent work repairing my furnace. The owner was very responsive to new codes with my city’s utility company and corrected some small issues. I recommend them and will use again. Great customer service and satisfaction. They deserve more than 5 stars.

We had an outstanding experience with Smith Heating & Air Conditioning, LLC when replacing our HVAC system. Not only did they install a new unit, but they also ran some new ductworksomething that required careful planning and expertise. Unlike other companies weve dealt with in the past, this company didnt just guess what we needed. Their team took the time to thoroughly evaluate our home and calculate the correct system size and duct configuration to ensure good performance and comfort, and were able to use a dual-fuel system.The technicians were top-notch: professional, courteous, and highly skilled. They kept us informed every step of the way and treated our home with great care. Just as impressive was their follow-through after the installation. They checked back to confirm everything was running smoothly and made sure we were fully satisfied with the results. Outstanding follow through after the sale.Having owned multiple homes and worked with several HVAC companies over the years, we can say without hesitation that Smith Heating & Air Conditioning, LLC stands head and shoulders above the rest. We cannot recommend them highly enough.

I can't say enough about their staff. Everyone is absolutely amazing between being knowledgeable to their customer service. Shout outs to Jack, Jimmy, Ethan, Heather, and Dean for just being amazing. I highly recommend this company for any HVAC needs. Thank you everyone who was involved with our unit, and the replacement of it. I can finally breathe and know that my family will be warm this winter and cool in the coming summer.

Spent the most time doing the job right than many other HVAC companies I have seen. Took pictures of everything before and after and did not try to up sale or hit with hidden charges like others have in the past. Identified immediate concerns and addressed and gave suggestion on things to consider or think about, but zero pressure. They will be getting my future work for sure. Thanks Ethan for doing such a great job
