Tried calling a few companies & put off for a week. However Smith & Willis was able to slot me in 2 days. Diagnosed problem & gave me options on solving. Monte completed work in just under a couple hours and took some time to makes sure synced with phone app. It’s been a week & knock on wood everything is working smoothly.

They installed my central air conditioning and furnace. I needed servicing today because a pump quit working to pump the water from the coils partially flooding my basement floor. When I called, they told me they only install new construction and they don't service their equipment they installed! Really!? They told me to call a reputable service company to fix my problem. What!? Why did I spend over $18K with you folks, and you don't service the HVAC that you installed? If I only would have known! Buyers be aware!

We just moved into a brand new house and the fan was already malfunctioning day 3. So first the positives, the company was able to make an appointment within 3-4 days of me calling. When the guy showed up he was able to find and fix the issue within five minutes.

The reason why I gave them only two stars is because when he was cleaning out the fan, apparently he just dumped a bunch of drywall and bugs into our toilet AND left it there! We had a guest come over an hour later and it was extremely embarrassing when they said “ummm you have bugs in your toilet”. How hard is it to first of all, put the bugs in some toilet paper and throw it in the garbage can right next to the toilet? and second, why can’t you carry around a mini broom and dust pan to clean up whatever mess they make at a customers house? You can literally buy them at the dollar store. Ugh!

Their work is completely garbage, got a new home from Lennar and every night I hear popping noise from the HVAC system. They have tried to fix it like 5 times and every time they fail, now they're saying it's perfectly normal. Even their own tech that came out said there's probably a tear or something jacked up with the system and told me to call a duct cleaning company and see if they can send a camera to look for tears. Wouldn't trust them near any furnace. Potential customers BEWARE
