My thermostat stopped working. Universal had a tech out the same day. He was friendly, identified the issue in minutes, and had it replaced quickly. The price was very reasonable, and he even gave me a quick tutorial on the new programmable features. Great job!
We replaced our entire aging HVAC system. From the initial consultation with Mike to the flawless installation by Jose and his team, the experience was top-tier. They were meticulous, respectful of our home, and explained everything. The new system is quiet and efficient. A five-star company!
I bought a smart thermostat online but was too intimidated to install it myself.Universal sent a technician who had it installed and fully integrated with my phone in under 30 minutes. He showed me all the features and how to set schedules to maximize efficiency. Fantastic service for the less tech-savvy!
They replaced a 60 year old furnace with this new Goodman 3 ton. The job went smooth and quick and the crew was clean and professional. I got the Google Nest Thermostat included with it and they paid the tax. It was easier for me to install and connect with the Nest App than the Google Home app so that is working and will be very convenient to control the furnace from a cell phone app.
Fast, Reliable, and Friendly! They came promptly during this crazy heat wave and got us taken care of quickly. Once I accepted their estimate — which was completely fair compared to two other companies I quoted — they came in, did the job efficiently, and even checked our other AC units to make sure everything was in good shape. The team was professional, friendly, and thorough. Highly recommended!
