Oil and Gas Boiler

A boiler works by distributing radiant heat throughout your home through a closed network of hot, water-filled pipes. While boilers are a very efficient source of heat, there are many parts to the boiler system that, if not properly maintained, could cause your boiler to break or work improperly.

Oil and Gas Furnace Services

A furnace contains a heat exchanger — heated by an ignited fuel source such as gas or oil — and a fan assembly to push the air through your duct system. Common issues we see during a furnace repair visit could involve moving parts of the burner and air assembly, heat loss in ductwork and electrical components.

Heat Pump Services

If you live in the Lehigh Valley area, you know how difficult it is to heat your home during the winter with a heat pump. Without a supplementary heating source, your heat pump will struggle to keep up with the demand to heat your home. Unlike a traditional air conditioning unit, a heat pump runs all year long, which means it needs maintenance and seasonal inspections.

Forced Heating Systems

With a forced-air system, heated air travels through a system of ducts and gets expelled through vents into the different rooms of your home to maintain your set temperature. Having reached the desired temperature, the heat will shut off until the temperature drops down again.

Many forced-air heating systems are remarkably energy-efficient and can keep your family comfortable all winter long.

Mini-Split Systems

Mini-splits are heating and cooling systems that allow you to control the temperature in individual rooms or spaces. Mini-split systems have two main components: an outdoor compressor/condenser and an indoor evaporator. 

Mini-split systems are not only great solutions for new constructions, but make excellent add-ons to homes with non-ducted heating systems. They can also be a good choice for room additions where extending or installing distribution ductwork is not possible.

When Your Broken Heater Is Beyond Repair

When we inspect your system, we will always give an upfront price estimate for your repair. However, if we see that your system is too old and in need of replacement due to poor energy efficiency or incompatibilities, we will propose a high-efficiency solution to replace your broken heating system.
