"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.

"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."
