A/C Repairs by Licensed HVAC Technicians

When temperatures begin to rise in the summer months, it’s crucial to have a functioning air conditioner to help keep you and your family cool. With the added load, your air conditioning system has a greater chance of developing problems or even breaking down as the temperatures peak. While there are many air conditioning companies that serve the Lancaster, PA area, simply randomly choosing one may not yield the best results.


For quality air conditioning service, consider our professionals at The Witmer Company. We have been in business for over 80 years and are one of the most trusted HVAC companies in the area. We provide HVAC repair, maintenance, and installation, as well as indoor air quality, plumbing, and water conditioning services.


Contact us at (717) 229-0741 and you'll always get a same-day response.

When to Schedule Your A/C Repairs

Before an air conditioner stops working completely, there will often be signs of an imminent problem, such as:


  • Higher utility bills
  • Reduced cooling performance
  • Ice accumulation on the evaporator
  • Leaking or dripping water
  • Frequently tripped breakers
  • Tripped compressor overheat switch
  • Hissing noises or visible refrigerant leaks
  • Screeching noises from the compressor
  • Banging noises form a damaged blower fan belt
  • Arcing or burned electrical contacts


If you notice any of these symptoms in your air conditioning system or have other concerns, contact our experts at The Witmer Company. We will inspect your system for problems and offer sensible repair solutions.

Emergency Air Conditioning Repairs When You Need Them

At The Witmer Company, we understand that air conditioners do not always malfunction at the most opportune times, and that is why we offer 24-hour emergency A/C repair services. With us, you can get the help you need any time, day or night, weekend or weekday.


For 24/7 emergency A/C repairs, call (717) 229-0741.

Air Conditioning Repair FAQ

  • What can I check before calling for A/C repairs?

    If you would like to avoid an unnecessary service call when your A/C won’t start or shuts down prematurely, first check to see if the thermostat has power, is working properly, and is set correctly. Make sure the air filter is not dirty or clogged, check for blocked ducts, then cycle the breakers for the system off, then on, to reset it. If the A/C still won’t start, call our HVAC experts at The Witmer Company for in-depth A/C troubleshooting and repairs.

  • Why is my evaporator frozen?

    If you notice frost or ice accumulation on the evaporator, refrigerant lines, or the compressor housing, shut off the power and call an HVAC professional for help finding the cause of the problem. In most cases, a frozen evaporator is caused by a clogged air filter, airflow issues, dirty coils, low refrigerant levels, or compressor problems.

  • Why is my air conditioner so loud?

    Some noise from your air conditioning system is normal, but if the sound changes, becomes louder, or you notice a new noise, it could indicate serious problems or mechanical damage. Grinding or squealing from the interior portion of the system could be a damaged fan, for instance, while screeching, buzzing, or clicking from the condenser unit outside could be a faulty compressor.

  • How can I improve the reliability of my A/C unit?

    The best way to keep your air conditioner running smoothly and increase its service life is to schedule A/C maintenance at least once a year. Between service visits, check your air filter monthly, and replace it when it is dirty or every three months, whichever comes first. Keep the area around the outdoor condenser unit free of debris, and make sure none of your ducts are blocked by furniture, drapes, or other obstructions.

  • How long will my air conditioner last?

    Most air conditioners, heat pumps, and ductless mini-splits should last 12 to 15 years before an A/C replacement becomes necessary, though some can last up to 20 years with careful attention to the preventative maintenance schedule..

  • Why is water leaking from my A/C unit?

    The condensate drain inside your A/C unit may be clogged, allowing the drip pan to overflow and spill. Call our team at The Witmer Company for help clearing the clog and avoiding water damage in your home.

"I have used their services for the past five or six years. They've always done a good job. But wow they knocked it out of the park recently. They put in a gas hot water heater earlier this year. Through no fault of their own, the heater just didn't work right. I was concerned and told John. the head of service. He said no matter what we will do the right thing even replace it if we have to to make things totally right.

Just a few weeks ago they came out and totally replaced the system. Thank you to them for keeping their word and for running their business the right way."
