"For years I have wanted to update my very old and inefficient American Standard cast iron boiler. I was very fortunate to find Mr Joe Burriesci the owner of Mayjac Plumbing who took the time to evaluate the best options, since the old boiler handled two apartments. We collectively decided to go with two Navien Combi Condensing Boilers, but the best part of the entire process was how meticulous the installation was done. From start to finish Mayjac Plumbing kept every promise and timeline made. I highly recommend Mayjac Plumbing..."

"APV Mechanical got onto the roof of my business and checked the a?c compressor and discovered that the "main" circuit breaker required replacing. They also checked the breaker panel breaker and found it to be functioning correctly. They then went to the air handler and discovered that the thermostat was not sending the necessary signal to the air handler. They repaired the problem and the a/c  is functioning as it should.
I will definitely use them again should the need arise.

"They contacted me very quickly. I requested a quote late at night and they called me at 10am the next day and they had a licensed plumber at my home within an hour of calling me. He was excellent, fixed the toilet bowl in 45 minutes and charged me $250. He was clean, professional and fast. I would recommend this company! I also contracted with them to repair my shower head and install a new bathroom sink. Everything was fully explained to me about the toilet and also what I needed to get for them to fix the shower and the sink. They will be back on Monday 9/28 (today is Saturday 9/26) to fix the shower. It will cost $275.00 + tax and I had to get the shower head. Not a problem, they told me exactly what to get. I had to order the vanity top, faucet and sink anyway so as soon as that is all delivered around mid-October they will return to fix the sink. Installation fee for the sink will run $975.00 +tax, and they are supplying the pipes under the sink, which all need to be replaced. They told me it will take around 5 hrs to install the sink. As this is in the future, I will leave a second review to report how things went, but I am very optimistic that things will go well judging by how they went today."
