Job Locations and Reviews
Upon arrival I did a home inspection last Friday. I gave the customer multiple options on things to fix/upgrade. Customer went with my quote. Work was performed today. All work was tested no leaks and a happy customer.
Arrived to complete previously approved work. Disassembled both outdoor units, removed accumulated grass and debris, and chemically cleaned both condenser coils from the inside and outside. Reassembled both units after cleaning. Installed a dedicated transformer at each attic unit to power its IAQ equipment, including the UV lights and electrostatic filter, reducing the load on each system’s control transformer. Cycled both systems on and verified proper operation following repairs. Both systems were operating properly, with no additional issues noted at the time of service.

HVAC System Diagnostic – Upstairs & Main Level Equipment: 2025 Goodman Gas Furnace & Straight Cool Air Conditioning System System Configuration: Three-Zone Zoned HVAC System Zone 1: Main Level Zone 2: Upstairs Zone 3: Upstairs Customer Complaint Customer reports that during the summer months, the HVAC system struggles to maintain the desired indoor temperature and does not adequately keep the home comfortable. Diagnostic Findings & Recommendations 1. Low Refrigerant Charge During the diagnostic evaluation, the system was found to be low on refrigerant. An insufficient refrigerant charge can significantly reduce the system's cooling capacity, cause extended run times, increase energy consumption, and prevent the home from maintaining the desired temperature.

For this job, I worked on replacing an outlet and cover outside on the back porch and outlet and cover outside at the dock. I also made a switched outlet into a constant hot outlet and put a free hanging wire in a box and capped off.
Today is I arrived I came and installed a new customer supplied Tesla charger in the garage area. There was already a 50 EV outlet in the garage. I use the wire for the outlet to power the new Tesla charger. Once everything was installed, the Tesla charged properly once power was turned on. I also checked on a receptacle that was worked on by another company recently. The new wire had broken off on the backside of the receptacle. I reattached it and once that was done, the receptacle worked properly. It was very nice to meet you today! If I can ever help you with anything else, please feel free to give me a call anytime. Thank you, Brandon

Very knowledgeable and educated me and husband on somethings going on in the house. A fellow vet.
From start to finish, Anthony was very helpful and informative. He understood the stress I was dealing with and made sure I understood what needed to be done so I could properly relay the information to the person in charge. He even took the time to write everything down for me, which I truly appreciated. His patience, understanding, and willingness to help made the entire experience much easier. Thank you, Anthony, for your excellent customer service!
Mr. Nathan Callaghan did an exceptional job with my HVAC check. He was extremely thorough, professional, and knowledgeable, taking the time to carefully inspect the entire system and make sure everything was operating properly. He explained what he was checking and answered all of my questions without rushing. I really appreciated his attention to detail and the care he put into the inspection. Its refreshing to have someone who takes pride in doing the job right and genuinely looks out for the customer. I would highly recommend Mr. Callaghan to anyone looking for a dependable and thorough HVAC professional! I will be asking for Mr. Callaghan going forward on any other HVAC issues that might arise.
I had a great experience with Marc. He was very kind and courteous. He was able to give me a quote rather quickly. He was very familiar with the faucet and water filter that I had ordered. The initial quote was a little out of my budget but he was able to work with me to get it in my budget. He did a great job and was able to install everything before I had to leave for work. This is the 3rd time I’ve used TE certified and the first time I’ve used their plumbing. I would definitely use them again.
He was very knowledgeable and helpful
The technician was on time early, very polite, professional, and thoughtful.
