Plumbing & HVAC Services in Upland, CA FAQS

What is the most common plumbing repair in Upland, CA?

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.

Will gas furnaces be phased out in Upland, CA?

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.

What annual maintenance should be done on an HVAC in Upland, CA?

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.

What should I do if my AC leaks water in Upland, CA?

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.

Friday morning, our dishwasher started leaking on the floor. I called Klaus and Sons and was very please they scheduled a plumber to come within a few hours. He found the problem but it was the dishwasher itself, not actually a plumbing issue. He didn't even charge for the visit. When was the last time you heard of THAT? I've been a customer for over 12 years and with that kind of treatment, you know why.
