My wife and I moved into our new house on Main Street Saturday. Monday night some boiler sensors went out on our radiators. Long story short our whole house started to leak from basement to 3rd floor. Their emergency services were ready to take our call at 9:30 at night. Jason walked us through how to shut off the boiler and step by step to keep further damage from happening.Fast forward to next morning less than 12 hours after the initial call took place Zimmerman’s had a technician in route to come take a look. Justin greeted us with a friendly smile and was master class in knowledge of our boiler and issues taking place. After a short time he discovered the reason for our problems. Soon enough we had a quote to fix our boiler.Not ready to jump ship and push our emergency to another day he asked if he could fix the boiler now. Justin worked for 2-3 hours until the boiler was up and running. Testing it multiple times to ensure it was functioning properly.Did I mention this all went down on 12/22 and 12/23 right before Christmas. I can’t thank Zimmerman’s enough for saving our holiday season and making us feel safe in our new home!

We highly recommend Zimmerman Plumbing and Heating in Mechanicsburg. We use them for all our heating & cooling needs. We got a new oil furnace several years ago. They had 3-4 levels of pricing. They’re not cheap, but their workmanship and Service is top-notch – the best I’ve ever come across in all my years. We have met Earnie Zimmerman personally. His guys are professional, super nice and trustworthy. We also used them for air conditioning splits in our house a few years ago- can’t recommend them enough.

I own a local small business and we had a clog. The Zimmermanns were helpful and extra attentive in helping me to get the issue resolved immediately and outside of my peak business hours. Having a reliable plumber is wonderful- having an honest plumber who understands the unique challenges of dealing with a repair quickly, cost effectively and with a cheerful disposition is priceless. I highly recommend using this incredible family owned and operated business- they get it!

Highly recommend!! They sent a plumber to my house for a sewer back-up in less than two hours of my call when they opened on Monday morning even though I was a new customer. I got a quote for a gas line to a new gas stove on Friday and some time over the weekend, we had a back up of water from a floor drain into our basement. Bill was thorough, helpful and knowledgeable and he and a second guy worked really hard to resolve the problem. I am so grateful for their service. They also installed the new gas line when they were done with the sewer problem. I’m a customer for life!

We recently had a very disappointing experience with the service company assigned by our home warranty provider. Upon arrival, the technician insisted our air conditioning unit had not been cleaned and refused to proceed with service until it was. They even offered to clean it themselves for $350 on the spot.Since we had EZimmerman clean the unit back in May, we immediately contacted them to clarify the situation. They responded with exceptional professionalism and understanding, and within two hours, they sent a technician to reservice the unit. As we expected, the unit was not as dirty as the other company had claimed. Nevertheless, EZimmerman recleaned it thoroughly, treating us with the same courtesy and expertise we’ve come to appreciate from their team. They did not charge us for the additional service, and their responsiveness and integrity truly stood out.We continue to be impressed by the quality of work and customer care at EZimmerman, and I will wholeheartedly recommend them for any plumbing, heating, or air conditioning needs.

I recently had a mini split system installed by Zimmerman’s and was very satisfied with the service I received. The communication was excellent and they thoroughly prepared for and executed the job. The team coordinated perfectly with one another and communicated every facet of the install and usage of the units to me. It was a pleasure meeting Earnie and his team throughout this process and I am extremely grateful for the level of service that I received throughout each phase of the process. I highly recommend them to anyone looking to have work done on their homes and I will be happily working with them again in the future.

First experience with Zimmerman, but it will not be our last. We had an electric problem, which we thought was not a danger. Although we called on a Saturday, Jayson arranged for Nick to come that day. Nick diagnosed the problem and fixed it. As we understand it, our issue was potentially dangerous. Thanks again for the wonderful service.

FAQs

This is a very common occurrence during the cooling season. Of course, heat naturally rises, but that’s not the primary culprit. A major contributing factor is the amount of heat that a second floor is gaining from the attic, many attics can reach 150° or higher in the summer. If an attic is under-insulated, this heat has no problem affecting the comfort of the second floor.

Second floors can also suffer from a lack of return air, while the system in the house pulls most of the warm air through the path of least resistance, i.e. the first floor, this results in hot air becoming trapped upstairs. Duct design and thermostat location also play major roles in temperature differences. Adjusting balance dampers can be a way to force more cool air to the second floor.

A Standard 1″ air filter should be changed at least every 3 months, even as soon as monthly during heavy use times and if there is a lot of activity from people or pets. Media air filters, usually 2″ – 4″ thick, will last longer, usually around 6 months, because of a bigger surface area. These can be changed annually in some cases.

Hard water is not necessarily bad for you to drink but it can have adverse effects on hair and skin. Otherwise, it is harmful to your home’s plumbing and any water-using appliances, resulting in a decrease in their efficiency and useful life.
