Great Service, repaired furnace where other companies failed!

Joey was very knowledgeable and showed me exactly what was happening causing my heater to fail. He went and picked up the part and repaired it the same day. Thank you so much for the HEAT!!

Great Service and Technician

Had Casteel come out and tell me we needed new furnaces upstairs and down. TE came out the following day and informed me both furnaces were fine after running some diagnostics. Technician Josh was informed and credible. Signed up for their maintenance program knowing their company's integrity.

Trustworthy and Thorough

We have an older home that required significant electrical updating. Jorge did a great job of identifying what needed to be done and was relentless in making sure everything was done properly. A pleasure to work with. They are now my go-to electricians!

Great service

I started using TE Certified a year ago and have been very happy with their service during that time. Both the HVAC and Electrical teams have come out to provide service and have done an excellent job.
