Routine Rinnai propane direct vent furnace maintenance

Aaron came and did our annual maintenance. He was very friendly. He made sure I understood pricing, did a good job cleaning up after performing the service, and showed me photos of the furnace guts before/after the maintenance.

Great Service

Had a great 1st experience with Jerms plumbing from a service prospective. I like the text and email appt. confirmations. They were very accommodating with appt. time. Tracey was detailed and communicative. Only reason I didn't give 5 stars is I'm not a fan of the $59 "Dispatch Fee". I understand charging a visit fee if no work is completed but don't agree with adding visit fee on top of $350+ worth of work. Also thought $350+ was a little pricey for re-setting a toilet & changing flange - wasn't quite an hour worth of work.

I had a couple of small projects done on one day. They did them all very well and described all of the options and pricing before letting me choose which direction to go. They were friendly and made sure to clean up any mess before they left. I appreciated being updated on the entire scheduling and arrival time via text, including a picture of the people who would be arriving at my house before hand. The whole process was very straightforward and the work was done well.

The primary bathroom sink was draining slowly due to a buildup in the drain line. Multiple applications of Thrift drain cleaner were applied and flushed with warm water, successfully clearing the blockage and restoring proper drainage; the sink was tested and confirmed to be draining correctly with improved flow. The existing 1” main shutoff valve for the building was not operating reliably. The water was shut off and the system drained, a new 1” quarter-turn shutoff valve was installed and clearly labeled for emergency use, then water service was restored and the system was tested with no leaks present at this time.

The customer-supplied water filter was replaced as requested. The existing filter was removed, and the new customer-provided filter was properly installed to ensure correct fit and secure connections. All fittings were checked and tightened as needed, and the system was tested upon completion. The filter is functioning properly, with no leaks observed, and the system is operating as intended.

Upon arrival the kitchen trap was leaking and the wet tailpiece was very corroded. I removed both and found the drain to be clogged. The threaded 45 by the wall was back pitched causing it to build up with food and grease. I snaked the drain and ran water down the drain and repeated the process until I was happy with the drainage. I then put the wye and trap back on and attached the dishwasher discharge hose back on. Everything is working well with no leaks at the time of service. I also built an estimate to replace a leaking cartridge for the soaker tub.

Installed new Viessmann 200 Series boilers in each building, including complete removal and replacement of associated systems. Scope of work included installation of new venting and condensate piping, required electrical connections, near-boiler piping, and the addition of new high-limit and low-water safety controls. Each propane system was pressure tested with a three-minute leak check to confirm leak-free operation. All heating zones were individually purged and balanced, with twelve zones per building addressed to ensure proper circulation. Boiler operating curves were programmed for maximum efficiency while maintaining consistent heat output and occupant comfort. Final startup procedures were completed, and all systems were tested and verified for proper and safe operation.

The bathtub was initially draining but doing so very slowly. An attempt was made to improve drainage by treating the drain with Thrift. After the treatment, the tub was tested and showed a significant improvement in drainage, flowing the way it should. The customer verified that the bathtub was draining much better following the treatment.

During this visit, the homeowner expressed concerns regarding a loose kitchen faucet handle and the need to replace the sediment cartridge. Upon inspection, we found that the internal components of the Moen Arbor faucet were loose, allowing excessive movement at the handle and cartridge; while there are no active leaks at this time, the handle is significantly worn. We discussed repair options and advised that, based on experience, the fixture will require replacement. As the faucet is a Moen product and the homeowner is the original purchaser, it should be covered under warranty; however, due to the holiday, the Moen service center was unavailable and will be contacted on the next business day to arrange a replacement. The handle was temporarily reinstalled and confirmed operational, and we will return at a later date to install the new faucet and replace the customer-supplied sediment cartridge.

During inspection, it was found that the oil furnace is very old and had not been cleaned or serviced in approximately nine years. The air filter located at the furnace was heavily soiled, and the blower belt was cracked and near failure. Upon removing the furnace cover, it was discovered that the combustion air intake was completely obstructed, preventing adequate combustion air from reaching the burner. With customer approval, the blower belt was replaced and a full annual service of the oil furnace was performed. This service included replacement of the nozzle, oil filter, and strainer; thorough vacuuming of the furnace; cleaning of the smoke pipe; resealing all smoke pipe connections with high-temperature RTV; and securing the smoke pipe to the chimney using furnace cement. During further inspection, the transformer wiring showed signs of overheating and melting, and the cad cell eye was found to be deteriorated.

Responded to a report of the recently added thermostat not properly responding. Upon arrival I found a mistake in the recent installation involving the wiring of zones. I provided a temporary fix to allow the thermostat in place to heat the bedroom, but we will need to return to address a permanent fix. All zones are heating properly at this time.

The existing tub/shower valve was leaking and failing to deliver consistent hot water, and due to prior unsuccessful repair attempts, full replacement was recommended to restore proper operation. Water was shut off and the system drained, the existing valve and trim were removed, and a new valve was installed on added blocking with new connections for hot, cold, and shower piping; new trim, tub spout, shower arm, and customer-supplied handheld sprayer were installed, the system was tested with no leaks or issues found, and all trim was sealed with caulking for added waterproofing. The existing mixing valve was leaking and had severely corroded fittings, so replacement was recommended to ensure safe and reliable performance. Water was shut off and the system drained, the failed valve and fittings were removed, and a new mixing valve was installed with new copper piping and adapters; the system was restored and tested with no leaks present at this time.

Installed four Aprilaire Wi-Fi thermostats and verified proper operation. All systems are working correctly at this time. The thermostats will need to be synchronized with the homeowner’s phone using the Aprilaire app. No one was home at the time of installation; the homeowner stated they would reach out to schedule a follow-up appointment if needed. I recommend performing an annual tune-up, replacing a leaking Hy-Vent on the boiler, and replacing the zone control board on one of the air handlers due to its age. I will provide estimates by Wednesday next week. We also noticed an active roof leak while we were in the attic..

For this job, we came out to inspect a reported blockage affecting the laundry area. Upon arrival, the customer demonstrated the issue by flushing a toilet, which caused water to back up into the laundry sink. This confirmed that the blockage was located further down the line, likely in the main drain. We explained our findings to the customer and recommended that Beards Sewer and Drain be contacted to properly inspect and clean the main drain, as we are not equipped to service main line blockages. The customer stated that she will contact Beards to resolve the issue. Customer would Also like a heat tech to look at radiator that is leaking.

Service was performed in response to the homeowner reporting that the sewage tank alarm was actively sounding. Upon arrival, the sewage system was inspected and it was determined that the pump’s float switch, which controls the pump’s on and off operation, had failed. The homeowner advised that the existing pump was over 20 years old. Due to the age of the equipment and the failed float, it was recommended and approved to replace both the sewage pump and float assembly to ensure reliable system operation. The existing sewage pump and float were removed, and a new pump and float assembly were installed. The sewage tank was properly resealed after installation. The system was then tested to confirm correct pump operation under normal conditions. Additional testing was performed by temporarily turning the pump off while running water to simulate a failure condition, verifying that the alarm system continued to operate as designed. All components responded properly during testing.

Arrived on site to replace 2nd failed damper. We removed the old damper and replaced with the new one. Wired it up and tested operation. Both dampers are working properly. Matt mentioned that after replacing the first damper, the main floor was still not keeping up. We looked into the wiring and configuration of the dual fuel system. We found that when the furnace ran 2nd stage heating it would hit the high limit rather quickly and cause an E5 error code to show up on the control board. Changed dip switch settings to allow only the Honeywell board to control heat stages. We also changed the discharge air temp limit to 130 from 145. The high limit trips at 150 which we believe was a cause of the furnace not keeping up especially at night. Propane should now kick on when it’s 40 degrees out. We asked Matt to monitor how the furnace performs after these changes. If it’s still not keeping up we may need to dig deeper into it. Thank you for your patience!
