This Goodman 13 SEER Heat Pump condensing unit is a new installation. The inside Goodman air handler attached to the heat pump condenser via line set was also replaced. It was replaced with this new Goodman heat pump. It’s not a good idea to put a new high SEER air conditioner or heat pump condenser without matching it. It should be matched with a properly rated and efficient air handler especially the coil. (more…)

Air Conditioner Ductwork Leaks | Leaky Duct Work - A good consideration when replacing the air conditioning system is the ductwork.
Red Arrow Shows a Duct Work Leak
Ductwork seems to be the most ignored part of an HVAC system. However, it is a very important consideration in this age of new technology and higher energy-efficient equipment being developed and manufactured. You can have the most energy-efficient engine but if it’s in an old 60 or 70’s model car your efficiency is going to suffer. The same is true with HVAC systems. (more…)
How Air Conditioning Works - Ever wonder how air conditioner works in a house? AC’s work by removing the heat from the space they service. An AC is simply a big refrigerator that uses the process of refrigeration to provide cooling for a building. AC’s work by using direct expansion coils or chilled water coils to absorb and move the heat from the air as air is blown across the coils.
Types of air conditioner systems that use direct expansion coils for cooling are window units, split system air conditioners, package unit air conditioners, packaged terminal air conditioners like the air conditioners used in hotels, and mini-split ductless AC’s. Essentially, an air conditioning system works by removing heat from the air. (more…)
HVAC 3R NEMA Rated Control Panels - These control panels offer resistance to inclement weather. They house the DDC controllers for two small chillers and two air handlers. The chillers provide chilled water for air conditioning to the air handlers. (more…)
HVAC Damper Actuator for Economizer Free Cooling - This damper actuator controls a free cooling damper for an economizer. It is part of an economizer damper system which allows free outside air cooling when the outside air temperature and humidity are ideal. In the Fall and the Spring when the outside air temperatures are mild it is unnecessary to run the air conditioning system to cool the building if the system is set up for free cooling. (more…)

In addition to the boiler do you have an air conditioning system with ductwork or a mini-split ductless system? Do you have a heat pump system? Do you have electric baseboard heating? Do you have an air conditioner system with electric heat? It is important to know the answers to what kind of HVAC system you have installed in your home. (more…)
Air conditioning preventive maintenance is a thorough check of the air conditioning system by a professional HVAC Technician. The technician will check the following:
