"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."

They did high-quality work at a very good price. They did an outstanding job with the work, with high attention to detail. Their communication was very strong from beginning to finish, their initial plan recommendations were excellent, they made several recommendations to not only make the job better, but also make it more cost effective along the way. They were reliable and consistent, and very genuine, "real" people. I have to imagine there will be very high demand for their services. I can’t recommend highly enough.

"Our family home has always been clean and functional but after thirty years it had become more a picture postcard from the 1980’s than the warm inviting image we had in our mind. It was obviously time to update. Unfortunately, after talking with numerous contractors, it seemed we would have to reduce our expectations or spend more than we had budgeted to afford remodeling our “dining room, living room, kitchen” (and eventually bathrooms too!) project. While pondering our next move a family friend told us they recently had Rohan remodel their kitchen/living space and it looked great and was, they thought, affordable. After seeing for ourselves the quality of workmanship, the improvements to ‘flow and functionality’ and the overall aesthetic appeal, we decided to give Rohan a call. Boy are we glad we did! Upon meeting Rohan for the first time we were shown the same optimism, knowledge through experience, flexibility of thought and dedication to quality that would continue straight through to the end of our multi-week project. His proposal/estimate covered all our wants and needs while fitting within our budget. The job was a total re-do and from floors to walls to counters to cabinets to plumbing to electrics and all were handled by Rohan and his team with time honed skill. The work was done in a timely fashion without ever leaving us wondering where people were or what they were going to be doing each step of the way. Every eventual ‘architectural surprise’ was met with candor, budgeted creativity and a hearty “no problem!” In the end our home was transformed ergonomically, aesthetically and affordably into a beautiful space where family and friends gather in happiness and in harmony with their surroundings. If you are considering remodeling your home we urge you to give Rohan a call. Boy will you be glad you did! "

FAQs for water heater installation and replacement projects in Helen, MD

You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.

For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.

Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.

Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.

A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
