What are some common plumbing problems?

Some common plumbing problems include leaks, clogs, and low water pressure. These problems can usually be fixed with a simple repair or adjustment. However, if the problem is more serious, you may need to replace some of your plumbing fixtures.

I’m a do-it-yourselfer. Should I handle plumbing repairs myself?

Some plumbing repairs are simple and can be handled by a do-it-yourselfer, but others are more complicated and should be left to a professional. If you’re unsure whether you can handle a repair, it’s always best to err on the side of caution and call a plumber.

How much does hiring a plumber or HVAC technician cost?

The cost of hiring a plumber varies depending on the type and scope of work, materials required, accessibility of the job site, and other factors. Simple jobs tend to be less expensive than complex ones. For example, replacing air filters in HVAC systems may cost less than a hundred dollars.

Nicole D. Nicole D.

Excellent service and response time!!! I called another company on a Thursday, and they said they would not be able to service my AC until Monday. I called Napps and explain what was going on with my AC, and I was told that someone would be there this afternoon, or in the morning. Within an hour, a technician called me and said they were on my way to my house. The technician did a great job of troubleshooting the problem. He was able to get my AC working within two hours. He did a great job of explaining to me…

Very nice young man gave me a lot of information about what needed to be repaired and replace. He went into specific details about combining a partial new unit with my old until and that I have a leak inside as well as the outside until. He was very helpful in so many ways. He was my ANGEL yesterday!!! Thank you
