"The old air conditioner was installed after purchasing new windows. The window company installed it as though it would never be removed. The prior handyman could not remove it after 3 hours of trying. Ivan and his worker removed it in 30 minutes. The entire job was completed in less than 90 minutes."

"Superior craftsmanship on installing the new cabinets."

"Very responsive and offered options for financing. The Legendary Service Team has a thorough understanding of regulations and offers environmentally friendly suggestions for your HVAC needs.

I will use them for all future maintenance needs."

"Leon was amazing! We had another company out a few days prior to look at our backed up drain pipe. When they arrived, they told us that the c/o pipe had to be installed outside of the house in order for them to rout and flush. They said our crawl space where the inside c/o pipe was, was not accessible, basically leaving us with no other option than a $4,700 estimate to install the c/o pipe. We wanted a second opinion. That’s when we called Top Tech. Leon arrived the next day and immediately recommended to rout out from the inside (even though the first company said this was not possible) first while using a camera to ensure there was no break in the sewer line. Even though a c/o pipe on the outside would be something beneficial in the future, we had just bought the house and were in no position to spend a lot of money. Leon and his crew came two days later and were fantastic! Not only did they clean out all the tree roots that were causing the problem, Leon was great enough to allow me to see the camera as it was going down- to ensure to myself that there was indeed no break. I felt like the previous company was trying to get a bigger job out of me, whereas Leon and Top Tech really has my best interests in mind- not just spending my money. And guess what!? It worked! He also gave me some great recommendations on things that can help with the root growth in the future. And hey, when we’re ready to get that outside c/o pipe installed- I know who I’m calling!"

"AVI installed my ecobee3 lite thermostat quickly and helped to set it up. They then showed me pictures they took of our condenser and that it was really dirty and so we had them clean it on the spot. Looks great. Will have them back for season maintenance"

"Val did a great job. He responded to my calls quickly, arrived at my residence on time and prepared. He diagnosed a faulty ice-maker on my 13 year old fridge and located and ordered a replacement and installed it. It works perfectly."

"Quick to respond, they installed a smart thermostat. Install went quickly and price was reasonable."
