HVAC reviews in Whittier, California

Bud and his colleague delivered top-notch service for our backflow system installation. Their communication was spot on, arriving on time as promised. They walked us through each step, ensuring we understood what they were doing. The end product is impressive - clean, sturdy, and well-designed. It's clear these professionals have a solid grasp of their craft and take pride in their work. We're thoroughly satisfied with the outcome and would highly recommend them for any plumbing or irrigation needs.

I've continued to rely on Marathon Plumbing Heating and Air for my home's heating and cooling needs since moving here. They met my expectations just as their predecessor did in my previous homes. When evaluating my old HVAC system, they presented me with three options and swiftly replaced it. The whole process was smooth, thanks to the technicians' professionalism. Notably, start-up technician Daniel went above and beyond by identifying a wiring issue that others had missed, addressing it efficiently while maintaining excellent customer service throughout.

Justin did an outstanding job inspecting and cleaning my furnace. His attention to detail was impressive, and he explained everything clearly. He even shared photos of the work done, which helped me understand the process better. I'm extremely satisfied with the service and will undoubtedly choose them again for future needs.

The plumbing valves in both showers needed fixing and so did the kitchen plumbing - unfortunately the walls weren't finished as promised. They left them open when they said they'd put panels in instead. When they cut into the walls to do the work, they accidentally severed an electrical line. It took five days for them to finally seal the walls. Although the job was done, there's still no electricity in the back of the house and we need to get a separate electrician to fix it. I'm leaning against using their services again for future repairs due to the cost - it might not be worth it.

I had hired someone to just replace the thermostat system, but when they opened it up, they found corrosion and leaks that required a full overhaul instead of just fixing the issue. The technician took pictures of the system before leaving, then promptly shut off the temperature control. When I turned it back on, the system refused to cool below 80 degrees - which was disastrous for me since I had bronchitis and couldn't sleep due to the heat. It's clear that my new thermostat is faulty because the previous technician never mentioned anything like this when they did a similar job in the past, implying they also didn't do it right.
