The Benefits of a Well-Functioning HVAC System

The core purpose of your residential HVAC system is to keep you warm during winter and cool during summer, but it should give you peace of mind as well. An HVAC system that is well-maintained and operating efficiently isn’t likely to break down suddenly or cost you more to run than necessary. It should also minimize your long-term costs while improving the freshness and cleanness of the air you breathe.

When you choose Horn as your HVAC company, you do so with the confidence that we’re going to deliver all of that and more. When you need new equipment installed, we’ll ensure that it’s the right pick for your home and wallet. Our team will install it with precision, and we’ll follow it up with seasonal tune-ups that reduce your heating and cooling costs in the short term and over the long term.

Reliable HVAC Repair, Installation & Maintenance

Horn Works with All Residential HVAC Systems

We’re here for you no matter which heating, cooling, or air quality technologies you have in your home. Our technicians work with electric systems and those that burn natural gas, heating oil, and propane, including furnaces, heat pumps, boilers, and ductless mini-splits.

Furnace Tune-Up


Central heating is the most common type of residential HVAC system in our service area. Furnaces are often paired with an air conditioner but can also provide auxiliary heating for a heat pump.

Ductless Heating and Cooling

Ductless Systems

Ductless mini-splits provide cooling and, optionally, heating without the need for ducts. Multiple indoor units can be connected to one outdoor unit in order to achieve a zoned residential HVAC system.

Heat Pump Tune-Up

Heat Pump

A heat pump provides central heating and cooling and is an alternative to the traditional furnace and air conditioning pairing. In our region, a heat pump is often paired with a backup heating system.

Boiler Tune-Up


Many homes in Pennsylvania have a hydronic heating system instead of a furnace or heat pump. Hot water and steam boilers do not blow air and therefore do not have a negative impact on air quality.
