"We were without water in 2019, and was dreading the cost and time when a plumber could come. Someone suggested this company and we called figuring we were going to wait a week or be charged an outrageous price, but what were we going to do. We called this company, and to our surprise, he came the next morning, he also installed a pump in our well, and we had water within hours, that same day! We were with out heat this Nov 2021. We had burned wood and then coal.Our coal stove went out, and we decided we were done messing with it. We called the same company, and Mr. Trump and Ben came, again the next day. They inspected and gave a estimated cost . We accepted and 2 days later Ben and another were here and installed a heat pump and returned the next day to finish the work so we had heat. The central air needed completed and as soon as they received the parts, they scheduled and completed that work too I would recommend this company to everyone. If he does for you as quickly, and efficiently as he did for us. You will be a happy customer. I need to add, he didnâ t gouge us because we needed immediate help. We didnâ t see any increase and were very happy with the end results. There was nothing to clean up after they left. They were polite and got the job done. Explained how to use the controls and answered all of our questions.Again, the price is so reasonable. And fast. When your without convenience of water, or heat on a cold night, it makes you really appreciate a business that makes it seem like no big deal. They can handle it. Iâ d recommend and will say this is one of the best , honest and trustworthy companies around this area."

"Mr. Raffensberger was extremely knowledgaable and was careful to do everything right and to a very high quality. Fees were very reasonable. I'm exceptionally pleased with the new high efficiency boiler installed at a different location than the old one was in our basement. It was necessary to run a lot of new hot water heating lines, add a natural gas supply to the boiler location, and add air intakes and exhaust through the walls of the old brick farmhouse. The new boiler is heating at a far lower cost than the old oil boiler from the 1950's. Mr Raffensberger didn't cut corners. The installation and operation are great!"

Water heater installations and replacements FAQs
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.
