Jennifer Lee
HVAC Technician
Energy efficiency specialist with 11 years in HVAC. Based in McKinney, serving all of Collin County. I do energy audits, ductwork sealing, and system optimization to cut your energy bills without replacing equipment. Many Collin County homes are losing 25-40% of their cooling through leaky ducts and poor insulation. I find the waste and fix it.

Energy audit + duct sealing - Stonebridge Ranch (HVAC)
Jennifer did an energy audit and found our ducts were leaking badly in the attic. After she sealed everything our electric bill dropped $80 a month — we could not believe it. She showed us thermal camera images before and after. Eye opening.
Response
Thank you Dave and Michelle! Those thermal images tell the real story — $80/month savings adds up to almost $1,000 a year. The duct sealing paid for itself in under a year.
Attic insulation and radiant barrier (HVAC)
Our attic was like an oven. Jennifer added insulation and a radiant barrier and our upstairs is finally comfortable. The AC does not run constantly anymore. She explained the science behind it all. Very knowledgeable.
Response
Thanks Lindsey! That radiant barrier makes a huge difference in a Texas attic. Your AC will last longer too since it is not working as hard.
Ductwork redesign - hot rooms fix (HVAC)
Three rooms in our house were always hot and we assumed we needed a new AC. Jennifer found a disconnected duct and undersized supply lines. Fixed for a fraction of what a new system would cost. Honest and smart.
Whole-home air sealing (HVAC)
Jennifer set up our Ecobee thermostats and taught us how to use all the features. She even enrolled us in Oncor's rebate program. Our energy bill went down $40/month just from smart scheduling. Simple but effective.
Response
Thanks Amy! The Ecobee with room sensors is a great setup. The Oncor peak time rebate is free money — glad we got you enrolled.
