Frequently Asked Questions

Top Reasons for Annual Maintenance
Dirty Filters Ruin Air Quality

Top Reasons for Annual Maintenance

Having high quality heating systems installed in your home is only the first step toward being comfortable all year round. It is also important to maintain those systems, so they keep running as efficiently as possible and keep your bills down. If you schedule routine maintenance shortly before the normal heating season, you’ll be able to avoid repairs and prolong the life of your system.

Dirty Filters Ruin Air Quality

The filter in your air conditioner and furnace are there to keep dirt particles from entering your ductwork and getting into your living space. Ideally, the furnace filter should be replaced every six months to a year and the furnace filter every three months. Sometimes, these times can change, depending on the amount of dust and dirt in your home, the location and overall usage. When the filters are allowed to get dirty and clogged up, particles will end up in the air ducts and eventually in the different rooms of your home. Keep the filters clean and your air quality will follow.

What Our Clients Say

Gene Johnson plumbing installed a new toilet for us, it was great working with them! Ishmael gave us estimates for various options, and we decided to buy our own toilet and have them come back to do the installation. Krystal did the install, and she was clean, efficient, very pleasant to work with, and the job was done quickly! It was also easy to schedule the work to be done. I would definitely work with them again!

– Lisa Henry

Another exceptional service call!…Alex was a true expert and he was very thorough and was patient while we went through our list of plumbing goals during this thorough full house inspection. He was able to give us some cost estimates on the spot. I certainly feel like I’m in the best hands and look forward to moving forward with our project.

– Ivan Archer

I had a new water heater installed with Gene Johnson this week and I was very happy with the whole experience. Eric Sams was my technician and he was incredibly knowledgeable and friendly and really took the time to explain my options to me. We have “unique” water heater systems in my place and he really knew what he was doing, I knew I could trust him. The installation was scheduled quickly and works/looks great!

– Ashley Curtin

Great experience with Branson! Very friendly, knowledgeable, and the quote was accurate. Needed shut-off valves installed on my house from the 40s, existing lines were galvanized steel, so that made things tricky. He outlined several options and recommendations, and we settled on something that will be compatible and easy to work with for future kitchen remodel plans. Will definitely be calling Gene Johnson again when it’s time to do more plumbing work!

– Brian Munn

I reached out to Gene Johnson regarding my radiant heating not working properly. They were able to come by within the next day to take a look. Tech Mike F was very knowledgeable and honest regarding next steps and questions my wife and I had. We proceeded to replace the Manifold and add a magnetic separator to my unit. Heat is now working! :)

– Phil Maaa

Prompt, informative, professional, friendly – very happy with service today.

– Francy M

Carlos was terrific!  He had the necessary parts on hand – he explained the problem, the solution, cleaned up after himself and now I don’t have water dripping under the sink!  Thank you Carlos!
