Plumbing & HVAC Services in Upland, CA FAQS
The most common plumbing repair is fixing leaks. Leaky faucets, pipes, or toilets are frequent issues that homeowners encounter. Typically caused by worn-out washers, damaged seals, or loose connections, these leaks waste water and can lead to water damage. Promptly addressing leaks with simple repairs or replacements can prevent further issues. While fixing leaks is a common DIY task, consulting a professional plumber is advisable for complex or persistent leaks to ensure a thorough and lasting solution.
The phasing out of gas furnaces is a possibility due to increasing emphasis on energy efficiency and environmental concerns. Some regions are implementing measures to transition to more sustainable heating options, such as electric or renewable energy-powered systems. However, the timeline for any phase-out varies by location and depends on evolving regulations and technological advancements. It's advisable to stay informed about local energy policies and consider more sustainable heating options as they become available and practical.
Changing or cleaning filters, inspecting and cleaning coils, checking refrigerant levels, lubricating moving parts, testing thermostat performance, and looking for leaks in the ductwork are all important parts of annual HVAC maintenance. Furthermore, make sure the system is operating properly, tighten connections, and verify electrical components. Expert technicians are able to carry out a thorough inspection, fix particular parts in accordance with system requirements, and spot possible problems before they become serious. Frequent maintenance ensures that the HVAC unit functions dependably and efficiently all year long by extending its lifespan, maximizing system efficiency, and preventing unplanned breakdowns.
If your AC leaks water in Upland, CA, first check if the condensate drain line is clogged and clear it if necessary. Ensure the drain pan isn't full or damaged. Inspect the air filter and replace it if dirty, as this can cause the coils to freeze and leak when they defrost. If the issue persists, contact a local HVAC professional to diagnose and repair the problem, ensuring proper operation and preventing further water damage.

Jake spoke with Kim about changing out 3 different shower valves in 3 different buildings. ALL DAY JOB. IMPORTANT: KIM WOULD LIKE 3 DIFFERENT INVOICES FOR EACH PROPERTY.


8 - 11. Per Jesse: Send Jake since he will be out here already. Check out water heater for this building UNIT B. Tenant said it is making gurgling sounds and has a blue light on. Jesse said to check out. It is still under warranty we installed it September 2024.

2 - 3 (TIME & DAY REQ). COD. Spoke to Ray. Front tub stopper not holding water and also wants to talk about handrails for shower and tub. Said that he tried to adjust stopper, kind that has brass fittings. Might have to replace whole assembly.

8-12. COD. CC on file. Call Myra she will be the point of contact (909) 931-1500. We've worked on the split unit a few times and now they're getting an error saying no fan movement and the unit is not working at all.

8-10. COD. Requested Sal. Call when in route. I spoke to Tom, they have a knocking sound in their kitchen pipes that happens when they run the water to it. They're unsure what the cause of it but noted that the noise is loud and sounds like hammers hitting the pipes.

1-5. COD. Text when in route. Service agreement member, diagnostic will be $99 dollars! Customer will not receive 10 percent discount off of that, but will get the discount if they agree to estimate for work depending on what is happening and the work will need to be written up on a separate ticket. I spoke to Gail, they had David out on the 20th of March this year, they noticed that their unit stopped heating over this weekend and did not turn back on. She is not sure what caused it.

1-5. CALL WHEN IN ROUTE. David returning to install part for customer.

3-5. COD. I spoke to Sherry, she is the daughter of Jim and will be the point of contact, (909) 225-4604 call when in route. Their thermostat is not working properly, they are not sure if it was not wired up correctly but it does not turn the heater on in the home. She also mentioned that she MIGHT want to have their floor heater looked at. I quoted $158 for the thermostat diagnostic and $350 for the floor heater diagnostic.

8 - 12. Spoke to Raul. He would like a maintenance on his AC to make sure it's all good before Summer starts. Also said that we replaced a heat exchanger inside the house last year, so he wants to make sure that's working correctly. Everything is working fine at the moment. Quoted $158.

(8-10) Spoke with Mike to confirm timeframe. Per Jesse, please clear the line again at NO CHARGE, due to it backing up again so quickly. They initially called in to get it re-cleared last week but wanted to wait to speak with a manager about pricing.
