We were shown options that he could install right then and there, and told how we could do it ourselves if we wanted a different thermostat. We chose a different one and installed it according to their directions. We have been toasty warm all winter."

David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

"PERFECT INSTALLATION WITH VERY PERSONABLE AND RESOURCEFUL PROFESSIONALS. I WOULD RECOMMEND THEM HIGHLY"

"We had no heat, and we had other companies come out and they said we had to replace our system. DNA heating and cooling came out and recommended we replace our system, but did offer other options. We opted to repair versus replace for the time being and the system has worked thus far. We would highly recommend this company as they were gloves, masks and booties over there shoes. The technician was extremely thorough with the unit, and he was able to communicate with me so I was able to understand and make an informed decision. When it comes time to replace our system we will definitely be using this company they have our business for life."

"The representative from Baltica arrived on time. Quickly diagnosed the problem (where previous plumbers could not), fixed the water pressure valve, advised me on do's and don't in use of the Noritz system. He also advised me that I should change the cap on the water heater, which was confirmed by the Noritz representative when I called the company. I would recommend Baltica any day to any one. Knowledgeable and courteous technicians. Reasonable prices. If you have tank-less water heater, don't use just any plumber, use Noritz certified technician. My heaters were previously incorrectly installed by licensed plumber, but he did not have experience with tankless."

"Carlos Chamorro from Southland Heating and Air Conditioning was very helpful and explained the details very well. He was on time and very friendly. He was very professional. I had a very positive experience with this company. They confirmed with me and gave me a half-hour window to meet up with them. Great company so far."

"Joe was amazing. He not only found a better A/C unit than the one we we were looking at (for even less than what we had originally budgeted) he also installed it perfectly. When we had a small issue (turned out to be low FREON) Joe came, replaced a valve and fixed it perfectly. Our new A/C is working great and Joe has been amazing to deal with. We would hire him again in an instant."
