Real Reviews From Real Homeowners

In honor of Women's History Month Frank's put on an evening plumbing class for women which I attended with a friend. Abby, Mike and Frank were incredibly welcoming and generous with their time for this free event. Mike and Frank traded off during the presentation and their passion for their work was obvious. They let us ask as many questions as we wanted and provided thorough explanations of common household plumbing issues. Always make sure your sump pump is plugged in before you call a professional!

I especially appreciated that they were very clear that they would not be making any sales during or after the class. If you want to set up an appointment you have to call the next day. There was no pressure to buy anything, it was truly just a free service to better the community and that is hard to find these days.

"The whole team was so very helpful and made me feel comfortable..."

Was visiting family and a drain clogged up. I had to leave next day out of state and Franks plumbing (Kyle) came by. Kyle was so friendly, went above and beyond. Have had plumbers play tricks before and not with Frank's. Will be using them for life. The whole team was so very helpful and made me feel comfortable that I could trust them to work with my family member who was at the house.

"They were excellent and I will never go with any other company!"

Al and Dante were amazing! Very polite and professional. Al explained everything to both me and my husband so we could actually understand what is going on. Al said the sump pump looks good other than the roots that are growing inside. He told us exactly how to fix that problem. He was able to get the hot water tank lit again, but did honestly say it will most likely need to be replaced. Thank you for your great service!

"Both of these gentlemen had pure compassion for me as a customer."

I wanted to share my gratitude to Mike Russo (manager) for taking a lot of effort to keep me happy and take care of my sump pump issue quickly and for sending out one of his best techs (Seth) who was fantastic! Both of these gentlemen had pure compassion for me as a customer. A lot of places just want to fix it, get paid and leave. People who take the time to listen to the customer and talk/explain/etc. are what matters to us homeowners.

"...Diligent in explaining and showing what was going on...."

Tanis was prompt, professional, courteous, and solved our problem well. He was particularly diligent in explaining and showing what was going on and left the work area super clean. Great work!

"So beyond thankful for Mike, Abby, and Frank for their hospitality today during their class!"

I cannot begin to describe the amount of information they provided to us all... and the truly best part…the community they are building. I truly cannot wait to go to more classes in the future. Because of this class I know without a doubt who I will be calling for any plumbing needs moving forward. Thank you, Mike, Abby, and Frank!”

    Many installations can be completed in a day, though timing depends on your home and the system being installed. We’ll set expectations before we begin.

    Not always. In some setups, you can replace AC equipment without replacing your heating system. We’ll evaluate your system and explain the best path forward.

    The right size depends on your home’s layout and cooling needs. We don’t guess—we evaluate and recommend what fits your home.

    Financing may be available for qualifying installations. Ask our team for details when you call.

  • How do I maintain my new AC?

    Regular maintenance and filter changes help your system run efficiently and reduce the chance of breakdowns. We can recommend a seasonal tune-up schedule.
