What Customers Say About Smith

Thorough AC Service from Start to Finish

Nate and Kyle did an outstanding job! They were punctual, thorough, and highly conscientious. They took the time to make sure everything worked properly and answered all my questions. They also installed an air scrubber alongside my new air conditioning unit to tackle a musty basement odor. I can't wait to see/smell the difference. Highly recommend!!!

Terri McNamara

Quality HVAC Replacement Without Surprises

Smith Mechanical Heating and Cooling has been wonderful for our family! Previously to new replacement, they came and maintained older unit until it had to be replaced. Nathan and Kyle are amazing! They were quick, mindful of our home, left ZERO messes, explained all the work they did/replaced. I can’t rave enough about the quality of work they do and how professional they are. Courtney in the office is excellent at explaining everything and making sure we knew what to expect. Zero surprise issues or hidden costs. The team also offers a maintenance program and comes to double check everything before winter/summer. Seriously amazing and kind team!

Courtney Searles

Professional AC Service, Excellent Results

Chad the technician was very efficient and professional when he came to service the AC! Also Kyle and Nate put in a new furnace and AC for my mother. They got her scheduled right away since we are having extreme high temps! Great couple of young men! They did a great job of explaining everything to us! The clean up was excellent! Very efficient! Would highly recommend Smith Mechanical!

Susan Hammerbacher

Expertise for Every HVAC System

Smith Mechanical HVAC service is great. Last summer we had then put in an Air Conditioner. This year we had then install our furnace. Nate and Kyle were very the best. These men were prompt, courteous, quiet, and worked hard to adjust the smaller new furnace to the duct work of our old 25+ year old large unit. Our dog took an instant liking to both men. I highly recommend this company and it's employees to anyone needing HVAC services.

Judy Schultz

Quality Work in Every AC Installation

Smith Mechanical installed a new air conditioning system for us. The Installation was in the attic. Nate & Kyle did an awesome job, answered all of our questions, very friendly & courteous. Going to have Smith Mechanical service our air conditioning system & boiler. Trust them to do a great job. Thanks guys!

Alana Beyer

Fair Service with Lasting Value

The technicians came the same day I called and repaired my furnace within an hour. A suspected chipmunk had made his way in our furnace, made a nest and did some damage. They replaced the parts and cleaned the furnace. I was educated on the age of my furnace and was provided with a very reasonable price to replace it when the time comes. They took the time and suggested ways to add heat to my garage. I was extremely happy with the very fair price I paid for repairs. I highly recommend this business and I will definitely use them again in the future.

Matt Mckellip

The Attention We Were Looking For

Our 30 year old furnace needed to be replaced, and of course it was winter. I got two estimates, but I was also searching for a new service company as our long time one had closed (retired) and I wasn’t happy with who was now managing our account. I selected Smith’s for their interest and attention to the project, the communication and the follow through. Great to work with, great product and the long term value we were looking for. They now have our business and we are pleased.

Robert Broekhuizen

Professional from HVAC Inspection to Installation

The team was great. I had them come out for an inspection which ultimately led to me needing a new boiler. Price was reasonable. They got me in fast. Jeremy and the crew were professional, helpful, clean and kind. I will be recommending to anyone who needs services.

Katie Wisneski

Fast, Knowledgeable, and Thorough

Called and got an appointment and was given a time range between 2-4 PM. Got a call that he was on the way and arrived promptly. Did a great job checking both the furnace and A/C. Would recommend them to anyone who needs service. Fast, friendly and knowledgeable.

Jill Balwinski

A Smooth Mini-Split Installation

Very Happy! Our first experience with Smith Mechanical. They responded quickly to our request for a quote. Every person we dealt with was friendly, knowledgeable and they beat the other quote prices. The install went smoothly, the Mini Split is working well to cool our property.
