Q/A: Filters
  • How often should I replace my filter?

    Replacing your furnace filter depends on your air quality and the type of filter you have. As a rule of thumb a 1” thick disposable pleated filter should be replaced at least every 3 months. A 4” to 5” inch thick disposable pleated filter should be vacuumed every 3 months and replaced every 6 months or 12 months depending on air quality.

  • How do I install my filter?

    Before installing the filter, make sure the power is off to the system. Different filters have different styles of access. Once you determine the filter access simply remove the old filter and install the new one with the arrow pointing towards the furnace or air handler.

  • How often should I clean my Electronic Air Cleaner?

    An Electronic Air Cleaner (EAC) should be cleaned regularly. The 4” to 5” thick electronic air cleaner cells need to be cleaned every 1 to 3 months depending on how quickly dust residue builds up on them. Even a thin layer will diminish the cells ability to remove particles from the air. Keeping the Electronic Air Cleaner cells clean is paramount for this filter to work correctly. The thin prefilters need to be cleaned at least every 3 months.

  • How to light my Furnace Pilot Light?

    Do Not attempt to relight your furnace pilot. All modern furnaces do NOT have a standing pilot and it is dangerous to attempt to light the pilot manually. If your furnace will not light, there is something else going on that will require a professional to diagnose and repair.

D. Lee

The technician was great: he knew exactly what the problem was and fixed it quickly and efficiently. Even when a glitch happened in the repair, he was totally prepared to handle the situation. I will definitely contact Day & Nite Plumbing for future problems. Thank you!

D. Thomas

We had a great experience with Day and Nite from start to finish. Chris was great at the no obligation consult. He explained things clearly and covered everything but didn’t waste our time. They also provided lots of options and thoroughly explained them but never tried to push or up-sell us. Installation was fast and very professional. We will definitely be using Day and Nite in the future.

E. Rubio

I had the privilege to meet Zach on two separate occasions within a two week span. He was upfront and honest about the work that needed to be done. He is a hard-working, dedicated, professional employee of Day and Nite Plumbing. He explained what needed to be done. I asked questions and he was patient and explained things further so that I truly understood.

D. Campbell

Very pleased with the professional technician, Donavan, who came out when our water heater quit working. This was the third major problem with this water heater, so we took his advice and replaced it. Thankfully, he was able to also install the new one right away. I had confidence in his advice and ability to do the job. He was thorough and friendly. It was a five star experience. I highly recommend.

S. Lippold

Outstanding Service! Scheduler was pleasant and receptive. Technician (Collin) communicated well, arrived in the agreed upon time frame, diagnosed the problem and fixed the issue quickly. Previously, we had two other companies misdiagnose the problem and one company stand us up for a scheduled appointment. If we have plumbing issues in the future, Day & Night Plumbing will be our first call !

M. Lindell

Collin was our tech and he was very knowledgeable answered our questions and what they charged was very reasonable and we are very happy to have water again. I was really impressed by everyone that we dealt with they all were professional and helpful.
