Zach is a Great guy to send out to meet new clients, analyze the situation, and generate a plan on the spot. He might take it a little slower when explaining the mechanics of plumbing, pipes, pumps, vents, etc. I have a masters in fluid mechanics and I had to work hard to keep up with him.

Amazing Teamwork and Top-Notch Service!

We recently had a service visit from Cody and Chris, and I was incredibly impressed. Cody has always provided outstanding service, and it’s clear he is helping build a team that holds the same high standards. Chris was professional, friendly, and eager to ensure everything was handled perfectly. They worked efficiently together, explained what they were doing, and made sure I understood the options before moving forward. It’s wonderful to see Jerm’s Heating and Plumbing growing while keeping their commitment to exceptional customer care. If you want a team that is skilled, trustworthy, and genuinely cares about their work, this is the company to call!

Outstanding Service-- Highly Recommend Jerm’s Heating & Plumbing!

Cody at Jerm’s Heating and Plumbing has been servicing my home, our rental property, and my parents’ home for quite some time and he is absolutely excellent. He’s reliable, knowledgeable, and always goes above and beyond to make sure everything is done right the first time. Whether it’s routine maintenance or an unexpected issue, Cody shows up timely, explains everything clearly, and delivers high-quality work at a fair price. It’s rare to find a company you can trust fully, but Jerm’s has earned that confidence time and time again from the very first time we met Jeremy (he's now a manager). If you’re looking for a heating and plumbing service that treats you like family and keeps your home running smoothly, look no further. We wouldn’t go anywhere else!

A new pop-up assembly was installed using plumber’s putty and thread sealant, and fittings were tightened securely.

The hot and cold cartridges were replaced due to the cold side not fully shutting off. After installing the new cartridges, the faucet was reassembled and thoroughly tested for proper operation. All functions were verified, and the faucet is now operating correctly with no leaks and smooth, reliable control on both the hot and cold sides.

-Installed a 2” pvc drain through the home’s foundation for a dedicated dry well drain for the existing water softener. An excavation company is in the process of digging the trench for the drywell. The 2” pipe has been piped through the concrete frost wall. The excavation company is going to connect to the pipe and extend it to the connection to the drywell. A drain receptacle was installed within the house, which features a check valve, air admittance valve, ptrap and air gap fitting. During a follow up visit the softener will be placed into service and a regeneration cycle. This follow up visit will be completed once the exterior piping is complete -Repaired the leaking 3” pvc drainage stack in the main floor bathroom. There was a dry fitted 3” sanitary t that connects the vent and the second floor drainage. The water from the vent was causing the fitting to leak. This connection has been replaced.

Arrived onsite to diagnose a possible gas leak on the water heater gas line in apartment #3. I had installed a Rinnai the previous day and noted a leak during our leak check that I suspected was coming from the existing water heater gas line. I performed a leak check on that line, and it held at 8.5 in/wc for 3 minutes with no pressure drop. When I went down by the meter, I noticed a gas odor. I bubble-tested the meter and found a small leak. Since the meter is typically owned by the gas company, I advised Mr. Walthour to contact them for repair.

Upon arrival customer had a leaking shutoff at their 1st floor lav, a shower with no hot water, and a garbage disposal they wanted installed. Customer wanted to wait to do garbage disposal. I disassembled Moen Posi-temp shower valve and found a corroded section of pipe on cold water inlet. I informed the customer and gave options for a valve replacement but they chose to move forward with just replacing the cartridge. I installed new cartridge and restored full function of the shower. I then removed the old leaking shutoff by unsoldering it. I cleaned the pipe and soldered on a new chrome sleeve soldered angle stop shutoff. I turned the water back on and tested everything. Everything is working well with no leaks present at time of service. Upstairs tub was found to have dysfunctional trip lever. Customer will follow up with a repair for this and the shower valve at another date.

Upon arrival, the customer reported that both the upstairs and downstairs radiators were not heating. I began a full diagnostic of the heating system and identified significant cold air infiltration around the piping entering from the exterior of the building. Accessible openings were insulated; however, a substantial amount of cold air continued to enter the structure. To further address the issue, I carefully cut multiple access openings in the walls to expose the piping and utilized a heat gun in an attempt to warm the affected areas. The supply piping extends across the ceiling and is currently not fully accessible for complete thawing or insulation. At this time, it is recommended that the customer have a qualified carpenter open the necessary ceiling and wall areas to ensure full access to the piping and to properly seal the cold air entry points. Once adequate access is established, we can return to fully thaw the piping and provide insulation as desired. The piping remained

Arrived on site to diagnose no hot water after new install. We found that the temporary water supply line we piped to the boiler when the water heater originally failed was allowing cold water to cross with the hot causing lukewarm water at the fixtures. Closed the valve and now we are getting sufficient hot water at all fixtures. This valve is okay to stay closed as the boiler is still being fed water. Water heater is operating properly.

Arrived onsite to replace a failed gas valve on a York propane furnace. During testing of the new gas valve, I noticed that when the blower came on, the flames fluctuated. I checked the carbon monoxide levels in the exhaust, and it was reading over 400 parts per million. Due to this unsafe condition, we are required to red tag the unit, and I advised them that it is not safe to operate. The furnace is approximately 15 years old and showing signs of age. When I originally diagnosed the failed gas valve, the unit was not running. I had also warned them at that time about the furnace’s age and the unknown condition of the heat exchanger. They would like a quote to replace the furnace and to install mini-splits. 1500 sq. ft house with a 80k btu propane furnace. 25 ft of 2 inch pvc vent with 5 90s. Needs filter rack. Return plenum 20 x 16.5, supply 19.5 x 16, only has 2 returns.

We removed the existing Symmons shower valve due to its ongoing leak and installed a new Delta shower valve to provide improved reliability and long-term performance. The wall was opened as needed to allow proper access, and the new valve was set in place with all required fittings, ensuring every connection was secured to current plumbing standards. After installation, the system was thoroughly tested to confirm proper operation and verify that the leak had been fully resolved. All work was completed in a clean, professional manner.

Arrived on site to perform an annual tune up on propane boiler. After our initial inspection, we provided an estimate to perform the work. It was accepted. We started by turning off the gas and power to the unit. We then removed the pilot assembly and burner tubes. We found that the thermocouple had some buildup on it and part of the nut looked like it had melted. Wire brushed the burner tubes and inspected the heat exchanger. Heat exchanger had some combustion particle buildup but it wasn’t terrible. Provided an estimate to replace the thermocouple but it was declined as he can do it himself. We then reinstalled pilot assembly and restored gas supply. We tested gas pressure and found it was only 6” w.c. This is extremely low as it should be 10” w.c. minimum. Adjusted it at the gas valve to get desired reading. Performed combustion analysis. System is operating safely at this time. Thank you for your business!
