Excellent Service!

Ty our service technician was great! Very friendly, personable, and he explained everything in simple terms along with both Pros and Cons. No pressure sales for recommended repairs and/or upgrades and replacement options. A pleasure to work with! Very happy with service provided.

Excellent Service!

Ty was on-time for the appointment, he is very courteous, professional, experienced, and thorough. He identified problems with my AC system, and fixed them right away. He also scheduled a follow up visit to make sure the problem is indeed fixed and no other issues exist. It was very pleasant to talk to him too. Thumb up! Also, it was a previous work by Thompson, they did not charge me for the service, I feel they are responsive and trustable company.

Couldn't have been better

Thompson was recommended by a friend who had used them. I am so glad she suggested them. The service, professionalism, timeliness and products are all top-notch as were the techs on the jobsite. We highly recommend them. Their pricing was WONDERFUL when we compared it to their competitors!

1. We opened an access at shower to determine where the leak was and why. We determined that the shower arm is loose and spraying water forwards which is running down wall in side tub. We recommend removing the shower head and re-installing with tight seal to stop leak. There appears to be damage at the base of shower where the water has leaked down wall. We recommend remediation or drywaller to remove and repair drywall. 2. The toilet is loose. We recommend pulling toilet and resetting. It might need a new toilet flange or just need to be reset with a new wax ring and hardware . 3. The venting on the water heater is older and is recommended to have it replaced from the top of the water heater to the roof. The water heater vent is not shared with any other fixture.

Removed and replaced the asbestos flue venting and replaced it with dual wall b vent to prevent flue gasses from reaching dew point and condensating back to the furnace. Performed a heating maintenance on the 1 yr old Bryant furnace. Replaced the filter and the system is running well and has no issues at this point.

For this job we replaced a 50 gallon water heater that was no longer working. Customer tried to re light the unit but it would not stay lit. Unit was approximately 7 years old. We installed a new Bradford White 50 gallon water heater. Added new supply lines, new expansion tank, new gas line and sediment trap. We also installed a new expansion tank and set the pressure to 65 psi. Comes with a 2 year warranty on the water heater from Thompson.

Customer will pay us the 360 for the leak detection. CPL does not take Discovery so we will be paying the service and the customer will pay us back.

No cooling from the downstairs unit. Inspection of the system showed there was no refrigerant in the system 0 psi. Given the age of the system and cost for repairs I recommended replacement. Trevor will be out to talk to homeowners between 10-12. 12 yr old carrier.

Install a customer supplied garbage disposal, as well as a thorough testing to ensure proper installation. Homeowner also bought the extension cord to connect to the new garbage disposal since the new one did not come with one from the manufacturer. After the installation was completed I ran water and checked for leaks. No leaks were found. The work preformed comes with no warranty since the disposal was purchased by the homeowner.

Inspection of the condensing unit showed the compressor making a light squealing noise. When testing the system I was able to locate the noise coming from the compressors internal components. Further tests showed the the compressor winging tolerances are out of tolerance. In situation like this the only option is to replace the compressor. Sent an estimate for the cost of labor and refrigerant.

Supply and install noritz tankless water heater, factory, 12 year warranty on heat exchanger. We will also installed new waterlines new gas light at new vent line through the roof. Also, when I opened up the vent pipe, it was broken inside the ceiling so I had to open up the ceiling a little bit to fix it. Luckily I was able to get it and not a problem. The only thing we need is patching in the garage just a little bit. I will text you a number for someone who does patching. Thank you also regarding a discount I will leave the price the same and not charge you for fixing the vent in the ceiling. I think that’s a nice discount.

Customer states that ever since they had the new stove top installed they could smell gas. They turned off the gas going to to stove top to be safe . When I arrived I turned the gas on and used my sniffer to locate the leak. The leak was coming from the gas line that connects to the gas regulator. Tighten the hose down and checked for leaks. No leaks were found. There is no warranty on this repair.

37 yr old furnace. Tested system functions and ignition of the pilot the first two times was longer than usual. Two tests afterwards the furnace ignited and operated as it should, even though the furnace is functioning I still recommend replacement of the system as the pilot not igniting right away poses a hazard and is unsafe. I shut off the gas and disconnected the furnace.
