It's unbelievable but some companies required upfront deposit even before assessment of the issue. Our technician,Brian,was on time,called prior,came with shoe covers,quickly identified problems with toilet,gave us estimates and couple options to think about. I called next morning and next business day he returned and completed repair. Again on time,very professional and leave no dirt or waste after job. Prices are horribly high now everywhere,but plumbing can't be avoided,so their price point is adequate to area,but service is superb. Can't deduct star for high prices,because they are using gas and supplies which are horrible now.

I hired Mike to fix a plumbing issue at our home which involved replacement of the innards of a…read moretoilet and a bathroom faucet. Upon arrival, Mike did a thorough inspection of the house's plumbing system and found some other issues that may cause problems down the line. He replaced those as well and saved us a huge headache! Mike and Anna are a great family business and do excellent work. He is prompt, communicative, and doesn't try to upsell you. It is important to be flexible with your schedule as a job prior to yours could take a bit longer than expected, but he will let you know if your time window changes. Would definitely recommend!

Requested an electrical service when a bathroom fan blew a circuit and tripped a breaker on the panel. Elijah Jordan was my service tech. He diagnosed the problem - some hack wire-splice job done on the fan motor itself that fried it. He got a replacement motor quickly and replaced it to ensure that it would last without compromising its functionality. He was quick and courteous and explained each component of the replacement so I could understand the scope of work and faulty splicing that caused the issue. Cleaned up all dusty and work areas and completed the job efficiently.

We recently called Cardinal Plumbing, Heating & Air for a leak in our very old HVAC system, and we…read morecouldn't have been more pleased with the service we received from Jay. One of my neighbors referred them to us. From the moment he arrived, Jay was professional, knowledgeable, and incredibly patient. Rather than simply fixing the immediate issue, he took the time to educate us about the various components of our aging HVAC unit and explain how everything works together. As homeowners in a condo community, we really appreciated his willingness to share his expertise in a way that was easy to understand. Although our building uses ME Flow, we did not trust them to service our issue. Jay also provided valuable advice on what warning signs to watch for in the future and what potential issues might arise as our system continues to age. He even showed us detailed photos of our rooftop unit, giving us a clear picture of its condition and helping us make informed decisions about future maintenance and replacement planning. What stood out most was Jay's attention to detail and his commitment to customer service. He never rushed the visit, answered all of our questions thoroughly, and made sure we fully understood our options. If you're looking for an honest, professional, and highly knowledgeable HVAC technician, we highly recommend Jay and the entire team at Cardinal Plumbing, Heating & Air. Outstanding service from start to finish! Our next step will be to get a quote for new unit to replace our 25 year old unit.

We were provided a quote quickly and were pleased that it came in around what we budgeted for the project. He even explained how to operate our HVAC damper after we assumed it was broken for years since the diagram for it was wrong. We've called Cardinal several times over the years of owning our home. To date they have replaced our water heater, furnace, AC unit, and a toilet. We have been satisfied every single time. I would even say that we've been impressed with how well each of their technicians communicate, how quickly the job is completed, and how high quality the work is. We look forward to working with them again for this humidifier.

There was an initial mixup about the appointment time, but that was soon sorted, and Saul contacted me prior to his arrival and arrived on time.

He also provided what next steps would be for a more permanent solution. It was a very professional, friendly service call.

Do not go here, they're scammers and extremely unprofessional…read more Similar to Julie A, whose review you should also go look at, I was bait and switched by this company. They said there was a $49 assessment fee to come out and look at my HVAC. (See attached screenshot of Yelp chat). When they got there, they assured me they could take care of the problem and would provide a quote. The visit ended with them charging me $219 somehow. I disputed the additional $170 with my credit card company because this is FRAUD. Even by their own invoice, they did nothing to earn anything past the $49 assessment fee and even that they don't deserve. They NEVER provided me with a written quote. Because I live in a condo building, they had someone call me back and say I would need to pay $10-15k to rent a crane so they could replace my HVAC system and that didn't include any materials, labor etc. Just the crane. They also said they would have to cut through my upstairs neighbor's unit for the repair and that I would be responsible for all of the costs of demolition and restoration. At the time, I was in a different state taking care of an extremely sick family member and when I asked clarifying questions about how they were going to do the HVAC replacement they just kept throwing out bigger and bigger numbers until I was deeply distressed. $10-15k for a crane, another $7k to run some tests on the lines that run to and from the HVAC system, an overall ludicrous quote of $40k--to replace an HVAC system!! They could've just said they don't want the job. They could've even refrained from following up. Instead they needlessly put me in distress and unjustly tried to take $219 from me while providing NOTHING in exchange. I ended up going with a different company who didn't try to take advantage of a young homeowner and didn't need to get a crane. Please don't go with this lazy, crooked company. Y'all should be ashamed of yourselves. P.S. I also had to ask for a time frame (see other screenshot). They said 9-11. Then I got a call at 7 am that day saying someone was on their way. I was not at all prepared and told them they had to come later.
