Jeff

Service Technician

I have been in HVAC industry since 2008 and a Tempco service and installation technician since 2013.

Local 265 sheet metal worker

Certifications - universal refrigerant, 410A certified, NATE certified, OSHA 30, fire life safety level one, certified master mechanic

I like being a HVAC service technician because there is something new each day. One day I may be installing a new furnace and air conditioner in a new house and the next day I may be fixing equipment in the attic of a 100 year old house. It is rewarding helping out customers with their HVAC issues and making sure their questions are answered.

Poor communication and code violation
Requested Tempco to install humidifier. Was recommended a humidifier and when asked about other models was told not needed. No issues there. Installer was professional and courteous. Recommended a friend for the same model and he was quoted 75$ less and was given an option between saddle and angle valve. Saddle valves are not code compliant. No such option was provided to me and when I checked I have a saddle valve installed which I am trying to remediate!

Joseph - Huntley, IL 60142
Terrific company/employees
As usual, our experience with Tempco is terrific. They installed the furnace and AC in our newly built home, and we decided after our first year to go with them for annual check ups of these systems, and any emergency work if needed. Could not be more happy with this decision. We have had two representatives of TEMPCO to our house for service, first Jason, and now Jeff. Jeff has answered questions we have had and given us some advice on some issues which we are thankful. Always on time, very kind and professional. We have a lot of confidence in TEMPCO and their employees if they are all like Jeff.

Completely satisfied!!
I was told they would send some out to check out my A/C between 9:00 & 11:00. Jeff showed up a few minutes after 9:00. Great start. He dug right in looking things over. The first thing he checked was the start capacitor which turned out to be the problem. After getting the unit going he further check the coolant temp. All good. We are very pleased and happy with the prompt service.
