Our Installations

Equipment We Install

We take pride in our work. This is why we go beyond industry standards when installing your equipment. It’s the extra steps we take that will keep systems running efficiently and safely for years to come, with the proper maintenance of course.

Our technicians are background checked, drug free, factory trained and NATE certified. Feel free to check them out on the Z-Team page. They will typically arrive between 7:30 and 8 to get the job started. Drop clothes and shoe covers will be used to protect your home as the old equipment is removed and disposed of and the new equipment is installed. If our installation is being done during extreme temperatures, we will provide temporary air conditioning units or heaters until your new system is operational. Once an installation is complete one of our team leaders will perform a 21-point system check and go over the system with the home owner.

We back all of our work with a minimum 1 year labor warranty, most of the HVAC systems that we install come with a standard 2 year labor warranty and up to a 10 or 12 year labor warranty!

  • How long can an installation take? A best-case scenario is that an installation service may take a day, while more extensive work can take much longer depending on what the job calls for. Just like houses, none of the systems we install are the same; they are customized to suit the needs of the home. We may not be the fastest installers for a job, and that’s because there’s an easy way and a right way to do things.
  • What do you need to do to prepare for an installation? We ask that a clear path is made in the home for easier maneuverability for tools and equipment. Also, as much space around the indoor unit as possible, ideally a 4’ radius. Exterior, we again ask for a clear path and space to work. We do our best to work around foliage to prevent any unnecessary trimming. Otherwise, clean and sanitary workspaces are a must.

A Wide Variety of Installation Options

What type of installations do we do? We’ve got a broad range to suit any of your home plumbing, HVAC and related needs, including:

If you need a ductless heat pump installation in Mechanicsburg, we can help. Ductless heat pump systems, or mini-splits, are advantageous in that they are small and flexible and can be used to heat one room, multiple individual rooms, or the whole house.

If you’ve been looking for an AC installation or heating installation contractor in Harrisburg or Mechanicsburg, look no further. Our certified technicians are the AC installation specialists, with HVAC technicians trained not only on basic home air conditioning installation but on installing multiple heating and cooling systems, including geothermal systems, standard heat pumps and more.

While you’re at it, you can check the search for a backup generator installation contractor off your list. Let us give you a free estimate on a new standby generator. Weather extremes are becoming more and more common in Central PA, so a whole-home backup generator is the sensible choice to protect you and your family. Automatic backup means if the power goes down, your generator immediately fires up, making sure your lights, appliances and other electricity-powered systems keep working when disaster strikes.

Is dry air a problem in your home? Air that’s too dry can give rise to a whole host of health problems, including colds and flu, and can even damage your home and increase your energy costs. We can install a whole-home humidifier system in your house to combat dry air, improve your home’s energy efficiency and make sure your home has the proper level of humidity.

If you have the opposite problem of too much moisture, it can be just as uncomfortable, if not more. A home that’s overly humid can:

  • Be a breeding ground for insects
  • Warp and rot wood floors and furniture
  • Create an unpleasant smell

It can affect your health, too, allowing toxic mold and mildew to grow and increasing the level of lung-irritating dust in your home. We can come to the rescue here, too, with a whole-home dehumidifier installation that will keep excess humidity down.

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

An accurately sized air conditioner is critical to the performance of your system and the comfort of your home. A load calculation should be performed by a professional to determine the exact heating and cooling needs of your home. There is no real rule-of-thumb as it encompasses much more than just the square footage of the home.

If you find your air conditioner frozen in a block of ice, it’s best to immediately turn the system off and let it completely thaw before any additional damage occurs. There can be several reasons as to why this happens.
First, check that the system is collecting warm air from the house by confirming that return vents are clear and the air filter in the system is not clogged. Bigger issues include low refrigerant or an issue with the systems fan. Regardless, this is a clear indication of a problem and should be diagnosed by a professional right away.

Dust is usually generated by the activity in the home, the more people, pets, and movement throughout, the more dust. It also infiltrates the home via air leaks. Dust can also be introduced by loose or detached ductwork in attics, basements, and crawlspaces. It’s important to seal gaps around the home and ductwork. It is also important that ductwork is properly attached and in good condition.

AC, HVAC and Plumbing Services You Can Trust
