Central Air Conditioning

Central air conditioners cool air from one central location in your home and distribute it through ductwork. When your AC isn’t working, you can trust Haller to fix the issue quickly.

Ductless system

Ductless Systems

These distribute cool air from a wall-mounted system and pump warm air through the outside unit.

Smart Thermostats

These devices allow you to set and control the temperature in your home remotely or on a schedule. If your thermostat isn’t connected or malfunctioning, call Haller for reliable thermostat repair.

Heat Pump

Heat Pumps

Heat pumps provide heat in the winter and cool air in the summer using a reversing valve.

If your heat pump isn’t cooling or heating properly, call Haller.



Furnaces use natural gas to warm air from a central location and circulate it through ductwork. A broken furnace can be uncomfortable during winter in Pennsylvania. Call Haller for fast furnace repairs.



Boilers supply the transfer of hot air in your home by heating a liquid (usually water) and distributing the heat through baseboards or radiators.



These add moisture to the air, either through your central HVAC or a stand-alone system.

Does Your HVAC System Need a Repair?

Signs your heating or AC system may need repair or replacement.

Dirt and buildup can prevent proper airflow within HVAC systems. A clogged filter, condensate drain, or water valve may be the culprit. Power supply issues will also prevent the supply of warm and cool air.

But often, problems are associated with older systems that are less efficient at converting energy into heat. Outdated parts in older systems are more expensive to replace. Consider replacing HVAC systems older than 10 years.

1. Temperature Change

Unexpected temperature changes may indicate dirt and buildup, power supply issues or frozen pipes.

2. Malfunctions

Malfunctions in your home’s systems, like humidifiers and thermostats, might be caused by circuit breaker issues or dirt and buildup.

Smells coming from your furnace could be caused by a gas leak. This should be treated immediately.

4. Strange Noises

Noise is often associated with parts of the system that are responsible for airflow.
