Heating & Cooling

When you’re at home you should feel comfortable whether it’s hazy and hot or frigid and snowy outside. An efficient and reliable home heating and cooling system not only provides physical comfort, but peace of mind as well. If your heating or cooling system does break down, it’s a relief to have a company that you can trust to perform an honest assessment of the problem and provide reliable repair work at an affordable price — that’s what we provide to our customers.

In addition to repair and maintenance, we also install new heating and central air conditioning systems for homes and businesses, whole home humidifiers and air purification systems, and geothermal systems. See the list below for additional services we provide.


Urgent Repairs for Your Heating & Cooling System

Heating systems seem to break down when you need them the most: on a cold winter’s night. Likewise, a cooling system is most likely to break on a muggy August afternoon. When your home’s heating or cooling system stops working, you want it repaired quickly and correctly.

Call us right away if you notice any of the following:

  • Heater or AC stops working
  • Furnace or blower is constantly running but temperature doesn’t change
  • Unusual smells or sounds coming from your system

If you are experiencing any of these issues with your heating or air conditioning system, contact Haldeman Mechanical immediately at 717-665-6910. An HVAC technician is on-call 24/7 and can respond quickly to fix your problem. We offer 24-hour emergency repair, as well as next-day scheduling for less critical repairs. Also, consider signing up for one of our Customer Assurance Agreement preventive maintenance plans to keep your system running smoothly throughout the year.
