I was pleasantly surprised with the company's after hours prompt service when our furnace tripped. A field technician came out to diagnose and thankfully we didnt have to go elsewhere or call for second opinion. Although, I thought it was fast service and the issue was resolved promptly, I felt there is room for improvement in communication, and overall servicing a clients home furnace.

Highly recommended. I used L.R. Gregory and Son to replace the central air unit in a remodel project, so cost was a major factor. They put a plan together for me that fit within my budget and finished the install within the time needed. In my experience, this is an honest company that cares about delivering for the customer.

I try not to be negative, but I need to share a very dissapointing experience with LR Gregory and Son. They were called out to assess our flat roof in Lake Forest. Not only did they quote projects that were not needed, their estimates for potential projects came in at 3-4x what others quoted. In total they estimated that we needed $30,000 for work that we were told from two competitors that could be done for $3,000-$8,000. I cannot speak to the quality of their work because I did not use them for obvious reasons, but I would SERIOUSLY recommend getting additional quotes before you go with this

Mr Gregory came to individually inspect my home. He offered a fair deal on pricing on a new furnace and home A/C unit. His men were quick and thorough in the installation, and answered all my questions regarding new unit operation, as well and parts and service warranties. This is a great family business to work with! --EL, Homeowner

LR Gregory and Son is my go to company for everything HVAC! Jim Gregory does great work and his service team is thorough and efficient. I've done my homework and their pricing is by far the best I've found. Great work!!

We had an A/C that was chronically malfunctioning. The staff at LR Gregory from the office, to the guys in the field, to the owner, gave the problem their full attention and did not give up until the problem was resolved. They even monitored the situation while we were out of town - with a key to our house. They are honest, trustworthy, friendly, and care about the work they do. I highly recommend this local company.
