Ultra Built In Systems Heating And Cooling

Called in Christmas Eve as our furnace which was used to tripping its limit switch had apparently stopped working entirely. After a quick Facetime call, we arranged for Paul to come over same day, he adjusted his schedule to come sooner which we deeply appreciated. He was very knowledgeable about our furnace system which was ~24 years old (original Carrier system from builder). After some diagnostics he confirmed the furnace was working just fine and we found that the thermostat had come loose that it wasn't communicating with the furnace, still had power but signal communication wasn't working properly. We properly reinstalled the thermostat and everything was working again.

What i especially appreciated was that Paul went the extra mile to check if the furnace was indeed working properly by measuring carbon monoxide, cleaned the flame sensor within the furnace and most importantly he used his diagnostic tools to determine that our gas pressure was set too high and adjusted it down lower. This explains why the furnace limit switch kept tripping past few years.

Super grateful for Ultra Built In System, a gem of a family owned company -- extremely honest and a true pleasure to work with. Highly recommend.
