What We Do

Most people would agree that we are becoming more of a “Throw Away” society. It seems like nobody wants to fix things that are broken, or make things that can be fixed.  

At Sheaffer Mechanical, we still believe that most of the time it is worth your while to fix what you have, instead of throwing it away and getting a new one.  You can save a lot of money by repairing that old unit and getting a few more years out of it.  We’re homeowners just like you, and we know how overwhelming that can be sometimes.  

It seems like all we hear from customers is how their past HVAC Service company always pushed a replacement system on them.  They made it sound like a brand new unit was the only solution.  

We’re here to change the way this industry has been operating.  Sheaffer Mechanical is dedicated to bringing every possible solution to your attention.  We will help you weigh out the pro’s and con’s, and work with you to find the solution that fits your needs.  While there are times that a total system replacement is the best option, it is almost never the only option.  

Give us a call today and we’ll stop out and take a look at any issue you are having.

 Is your furnace acting up, or has it quit altogether?  

Are you researching different companies on the web trying to find one that will work efficiently to fix your furnace for an honest rate?  

Would it be nice to find a company that will never try to sell you a new furnace when all you need is a repair?

If you’ve answered “Yes” to any or all of these questions, then please look no further.  We’re exactly who you’re looking for.  At Sheaffer Electric & Mechanical LLC, we enjoy the challenge of diagnosing your furnace problem and trying to fix it as quickly as we can.  We enjoy what we do.  

We were raised in a time when things were made to be fixable, and if it was broken, you fixed it.  With economic times being what they are, we can’t afford to just throw things away and buy new ones.  And Furnaces are made to be fixed.  With all of the built-in safety systems in your furnace, most “No Heat Calls” are just a small sensor that’s gone bad or a wire connection that came loose.  

As with any of our work, you the customer, are always in control of what’s going on.  First, we’ll find the problem.  Then we’ll inform you of the situation and discuss the options for repairing the problem.  Once you give us the “Go Ahead,” we’ll get your furnace back up and running at peak performance in a quick time and in a professional manner.  


Whether it’s a Rheem or Ruud, ArcoAire or Heil, Lennox, Bryant, Carrier, Gibson, Goodman or whatever;  It doesn’t matter!  We are experienced in all makes and models.  Our fully stocked trucks ensure that we will be able to overcome any obstacles and get your house back up to temperature sooner.

Hopefully, the temperature in your house hasn’t dropped while you’ve read this page.  But if it has, please don’t get any colder. Call us now to come out and get your home back to a comfortable temperature. 

Installation Services

Some HVAC companies have a separate crew that will only do installations.  They are usually paid minimum wage, and they only know how to do exactly what they are instructed.  When faced with an unexpected dilemma, they usually lack the field experience to make the correct decision and deal with it properly.

Don’t let this happen to you.  I have seen all too often the mistakes made by rookie employees.  You can always spot the Furnace or A/C that’s installed by a novice, whether it’s leaking ductwork, rusting cabinets, un-level units, or most commonly, equipment that is positioned in a way that it cannot be accessed for servicing.

It’s not their fault.  They are the new guys, and the installation market is often so cutthroat with its pricing, that the company can’t afford to assign higher-paid techs on the job.  Is that what you want to deal with?

At Sheaffer Mechanical, we understand the importance of a quality installation.  We apply our field experience and service background to every installation we do.  Mainly because we hope to be the company that is hired to service it.  With a wide range of brands and models, we are able to fit a system to any house and to any budget.  So give us a call, and consider the overall quality of the install, and who will be doing it.


We’re skilled at all levels of plumbing repair & installation. If you’re having plumbing issues, look no further, we can help. We specialize in, but not limited to:

•Pipe Repair •Well Pumps •Pressure Tanks •Water Heaters •Kitchen Faucets •Bathroom fixtures •Exterior Hookups •Water Softeners

If I’ve learned one thing in this industry it’s this: 

Water Destroys Everything it Touches! 

The only variable is how long it will take.  And of course, there are a few exceptions to the rule (like certain plastics) but you know what I mean.  If you’re reading this page, it’s likely that you’re experiencing this first hand.

At Sheaffer Mechanical, we are skilled at all levels of plumbing repair and installation.  From well-pumps and pressure-tanks to water heaters and kitchen faucets, we’ve got you covered.


This is what your well pump pressure tank should look like.  Stainless Steel fittings are the only way to go nowadays.

All of our materials are purchased locally and we stand behind them 100%.  We use professional plumbing products such as our Rheem Professional series Water Heaters.  You may find Rheem water heaters at the box stores, but they are not the same quality as our professional line.

We also use the most up-to-date and current techniques and materials to ensure long-lasting quality work provided in a more timely manner.  An example is our use of copper press fittings.  Instead of soldering which involves way more time and prep (and fire safety), these fittings use a special tool that permanently crimps them to the copper pipe, resulting in a permanent lifetime, leak-free fitting at a fraction of the cost of soldering.  These fittings can be installed with water running through them, as opposed to soldering which needs to be completely dry in order to achieve a good joint.

If you need some help with plumbing in your home, give us a call at 717-917-9955


What makes us different than our competitors is Honesty, Integrity, Trustworthiness, & Reliability.

When the time comes that the best option is to replace your current Air Conditioning system with a new one, Sheaffer Electric & Mechanical is ready to help you every step of the way.  We understand that nobody wants this to happen, and it can really be a stressful situation.  

Communication is key to this process, and our customers are never left to wonder.  You will be informed of all the brands, options, and prices so that you can make the best decision for you and your household.  

Even though we are now well into the 21st century, some houses in the Lancaster area have no central air.  That’s okay.  Sheaffer Electric & Mechanical can find the perfect type of system to fit your house’s needs.  Whether it’s a conventional system, a high-velocity system, or the highly efficient ductless mini-split systems, we will discuss and find the right system for your house and budget. 

IMG_0330 (2)

We have a few brands that we choose to install.  Rheem, Ruud, Goodman, Amana, SpacePak, Unico, Daikin, and Mitsubishi.  Sometimes the customer has a preference, sometimes the budget will dictate.  Never-the-less, we have a multitude of options for you when the time comes to install a new Air Conditioning system.


So whether you’re replacing an existing system, or installing Air Conditioning for the first time, let Sheaffer Electric & Mechanical help you through this process.  Our great rates and payment options are only paralleled by our attention to detail and quality of work.  

If a high-velocity system is what you need, you will receive an extra 5-year warranty on parts and equipment because we are a SpacePak Factory Authorized Installer.

We’ll perform a “Manual J” Heat Load Calculation on your house to figure out the exact cooling demand of your structure.  No two homes are the same.  Your A/C system needs to be designed specifically for your home.  It’s not a cookie-cutter process.  

Call today for a FREE in-home consultation.

Electrical Repair

Time is Relentless.  

That’s why you’re here.  Now.  Because something in your home or office has finally reached the end of its life of service.  Was it a premature failure, or did it really go above and beyond the normal lifespan?  No matter.  We’ll fix it for you.  The only question left is; Can we repair it, or does it need to be replaced?

The meter base that you see to the right is not repairable.  Even if you could find new parts for it, the utility company would not allow it to be energized anyway as it doesn’t meet today’s ever-changing requirements.  Sometimes the question of fixing or replacing is answered for us by the National Electric Code or the Local Utility Company.  Sometimes, it’s just not worth the time to repair something.  We’re here to help you know the difference and make a well-informed decision.  After all, it’s your money at stake here.

Meter Base

At Sheaffer Mechanical, we take pride in one thing above all else, and that is pleasing our customers.  We know that most people are not expecting things to break, and some people may not have the ability to replace and upgrade when that time comes.  No matter what the issue is, we will work together to find a solution that not only fits your budget but also gives you the peace of mind knowing that it was done right.

Growing up on a Dairy Farm, I never had a choice in the matter. You had to find a way to repair things.  Quickly and economically too.  That mentality still leads the way for me.  Repair is always the first thought on my mind, but then I step back and start looking at the bigger picture.  And maybe depending on the situation, replacing would be the better way.  The homeowner always has the final say.

The panel box to the left was installed to replace 3 different fuse boxes that served a small house.  That’s how they did it back then.  You started out with a 4 circuit fuse box.  Then you had to add another box if you wanted some more circuits, and etc. etc.  When this house was being sold, the seller knew that it would save him in the end if he just replaced those fuse boxes and installed a new panel and meter base.  Now when that home inspector comes through, there won’t be anything to mention.

Electrical Installation

We all know how important electricity is in our lives.  It powers everything!  Stop and try to think of something in your life that does NOT run on electricity.  OK, your car.  And your bicycle.  But that’s it!  Everything else depends on the flow of electrons in order to work.

I am reminded almost every day of how our usage of electricity has grown and grown.  I go into older houses and hear the same old thing.  “This room only has ONE receptacle!  What were they thinking!”  The answer is; they were right on target, for that day and age.  When some of these houses were built, the only thing that ran on electricity in the home was a lamp and a radio!  Needless to say, that has changed.  Even from the ’60s and ’70s, the use of electricity in our lives has increased many times over.​

So if any of this sounds familiar, or maybe you are thinking of making some changes in your house, and they involve some electrical changes or updates, you’ve all come to the right place. With over 15 years of house-wiring experience, I’m not going to say I’ve seen it all.  But I have seen just about everything I need to.  With a specialty of running wires in very tricky places, we can get that job done, and leave no sign of ever being there.  


 Whether it’s a ceiling paddle fan, a chandelier, a generator, jacuzzi hot tub, dimmer switches, recessed can light, new LED lamps and fixtures, a new Breaker Panel Box, outdoor motion sensor lights, over-the-range vent hoods, GFCI outlets, sound system speakers, sub-panels and surge protectors just to name a few, we can surely help you with this project.  

One thing I always hear from homeowners is that some contractors left a huge mess when they were done.  And though it’s not that big of a deal, it has always been one of my pet peeves. Leaving the house in a better condition than it had always been a main focus of mine.  Sometimes the hardest or largest part of a job is doing something that nobody will ever see; running wire in a wall.  Half of our work is never seen.  So when the only thing the homeowner sees that I did was leave a mess, that is not acceptable.  

So if you’re looking to get some electrical work done, and would like to hire someone that will work WITH you, and make you feel at ease, please consider Sheaffer Mechanical.  We are dedicated to our 100% Customer Satisfaction Guarantee.
