Importance of Office and Home Air Quality

Home needs to be a safe place that keeps hazards away from you and your family. Yet, the Environmental Protection Agency stated that indoor air is often 7-19 times poorer than outdoor air quality.  Our HVAC services can improve your home’s air quality by ensuring your HVAC system is functioning properly, helping you remove particles and pollutants while controlling the moisture in the air.

What Customers Are Saying

Google Review

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.

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!

Absolutely love them, they are fabulous! They are awesome. They have been awesome. They have done our air conditioning, our heating, and they replaced our roof as well because they do roofing as well. They are number one. We go to them now for anything that we need.

They have been servicing our furnace they have installed a new central air conditioning unit for us. We have them out usually twice a year for furnace inspection and the air conditioner inspection to keep everything running well. The last time they had to do a major install, thank goodness, was a couple years ago. It always goes out on like either the coldest day of the year or the hottest day of the year, you know, and that is what happened. And they were awesome with the quick turn around and, you know, making sure I think we were only out of a air conditioning unit for two days, maybe three, but that was also because we had called other people in the meantime, so, you know, just to get estimates, but they were awesome. They need to come out and do the regular service and to just check up on the air conditioner.
