"Excellent,prompt,courteous and professional service all the way from initial contact from ARS quickly reaching out to me to set up an appointment to the work done by their technician. He arrived on time, was friendly, professional and proved to be very knowledgeable and skilled in his profession. He quickly identified the problem with my water heater and had it fixed in a short amount of time. I am very impressed with ARS and will use their services again in the future for any plumbing needs.

"I had heard good things about Alpine and decided to give them a try.  I called right before lunch and asked if they could send someone out to get my air conditioning working.  Alpine was willing to accommodate my schedule on a work day and showed up on time.  Met with Ricky and explained the situation.  Prior to coming inside, he put on some little booties so as not to bring in any unwanted dirt or dust.  He evaluated the situation and explained that the drain line was stopped up and that the aux drain pan had water in it which shutdown the system.  Ricky cleared the line and removed the water from the pan so that the float switch would reset.  Shortly thereafter, the AC was running again and starting to cool off the house.  

From the initial phone call to the dispatcher to the service to the cost, and emailed receipt, I was completely satisfied.  I would highly recommend Alpine HVAC Services to my friends and others.

Water Heaters FAQs, answered by experts

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.
