"I'm gradually switching from gas to a mostly electricity-powered home. C.A.B. didn't try to talk me into go with the same old fossil fuel water heater. Other plumbers wanted to take the course of least resistance and just install another gas unit. C.A.B. had the expertise and initiative to take on this complicated, future-looking project. We never run out of hot water!"

"TopTec responded immediately, scheduled the appointment for 8AM the next business day. Jason the plumber arrived early, concisely explained his planned actions, coordinated with other trades, professionally executed the installation of the tankless heater with minimal disruptions, cleaned up and left a happy customer. Toptec did an excellent job, for my next plumbing issue I will call Jason at Toptec."

"It couldn’t have gone better! Carl was experienced, knowledgeable and friendly. Plus, he smelled gas which is why he replaced the valve on my water heater. It was a great visit!"

"We actually had called Emanuel Brothers first since their name was on the water heater. But, after the amount of time and money they quoted us I decided to check Angie's. We had John come out and take a look and he told us he could do the same work for almost $800.00 less! I can't say I didn't have some trepidation. First, just how is it possible to do so much less work than we were told would be necessary (we had 2 water heaters. Neither of which worked after nearly 20 years, that had to be removed first to make room). And, for so much less. Emanuel Brothers were so perplexed by our situation that they had to call the boss to come out and explain everything to us. But, John had this "no problem" kinda attitude. Both refreshing and disconcerting. But, in just a couple of hours he had not only delivered a new water heater, he had the other 2 removed and the new one installed. And its been working flawlessly.

"J. Blanton did an excellent job installing two brand new water heaters in my two flat.  After searching, talking to friends and family, and getting several estimates I decided on J. Blanton.   From the onset, they were courteous and patient with me.  It took some time for me to respond to the initial estimate and another month to schedule the installation but J. Blanton was patient with me  (my water heaters were still functioning but barely hanging on).  I even had to reschedule installation twice yet they were pleasant each time and patient with me.  
On the day of installation, they arrived promptly as promised and in fact the office called letting me know their plumbers/truck had left their yard.   This was very comforting, since I tend to become anxious, in general, when waiting for appointments and service calls. The installation went as outlined and by 2:00 pm that afternoon I had my water heaters installed.  Soon after I had hot water.  I was so happy!
As they began to clean up, the mature plumber of the two,  took time to review the features of the units.  He showed me the warranty and pointed out other functions.  I was very impressed!
I would absolutely use them again and recommend they to friends and family."

"I had Azrikam Heating (Azrikam The Price Is Right Heating) out today replace a part on my hot water tank and to take a look at my HVAC. 1) I am a new customer and even with other calls Bernard still came out to service my home 2) there is no bs. Any other person would tell you replace a unit when a part goes bad and the unit is 10 yrs old but no. Bernard looked at my system (paired water tanks), took pics for future reference, replaced the part and let me know that there is plenty of life left with both units. 3) Bernard is just a down to earth good person looking to give good services and guidance in his area of expertise. Put this company on your speed dial for home maintenance and repairs today."
