“We had a great experience with Kalka Plumbing. They came out three times to repair my Kohler smart toilets, and every visit was professional and punctual.

Derek was exceptional. He was knowledgeable, experienced, and clearly knew exactly what he was doing. He arrived on time, was friendly and courteous, and took the time to explain the issue and the repair process.

What impressed me most was his dedication to getting the job done right. After one visit, an issue still remained. I contacted Kalka, and Derek returned the very same day I requested service and successfully fixed the problem. That level of customer service is rare these days.

I truly appreciate Derek's professionalism, responsiveness, and commitment to customer satisfaction. I highly recommend Kalka Plumbing and especially Derek for any plumbing service needs.“

“We had the most amazing experience with Rooter Hero Plumbing! Our 50 year old plumbing system decided to retire without authorization and backed up (you can imagine what) into our new bathroom and toilets. Emergency call and Rooter was there in 3 hours. They quickly identified the problem, were so knowledgeable and thorough. They stayed until almost midnight for the initial phase and the next 2 days over the weekend replacing. I simply can’t say good things about our experience. I would call them anytime in the future asap!!!!“

“We met Avi when he was servicing our neighbor across the street. He kindly came and evaluated our unit in the middle of the night and gave us an honest answer, a simple change of filter could solve our problem. This is the most honest, well experienced (over 22 years) company I have come across. Highly recommend !“

“Kemnitz upgraded my AC & Heating unit in 2019 and has been providing annual service ever since. Jason just performed it, for a very reasonable fee (less than $200). Very knowledgeable and friendly. Left behind a detailed invoice explaining what exactly was checked. Does not try to upsale on repairs that are not considered necessary. I am soooo very glad to have established my relationship with Kemnitz! PS: their dispatcher Kalie (may be misspelled) is also wonderful to deal with on scheduling the service.“

“Diamond Air exceeded every expectation. We reached out after noticing our heating system wasn’t performing well—and with kids in the house, comfort is a big deal for us. From the very first interaction, the team was responsive, professional, and incredibly knowledgeable.

They took the time to assess not just the unit but our entire system, and explained the issues in a way that made total sense. What really stood out was how much they cared—about doing quality work, about our budget, and about making sure we were truly comfortable with the decisions we made.

We ended up going with a system upgrade, and I can’t tell you how much it’s changed our day-to-day. Every room in the house feels just right now—no more constantly adjusting the thermostat or piling on blankets. It’s made our home feel so much better, especially during cold nights and hot afternoons.

They showed up on time, cleaned up after themselves, and finished ahead of schedule. You can tell this is a team that values integrity and customer satisfaction above all.

Highly recommend Diamond Air to anyone looking for HVAC work done right the first time. Local, honest, and truly the best in the business.“
