HVAC Furnace Filter Basics | Indoor Air Quality - Pollen, molds, and dust are common in any household and can be reduced by using an air filter. To maximize the benefits from the cleaner indoor air you should use electrostatic furnace filters and air conditioner filters along with a high-efficiency air cleaner. Electronic Air Cleaners (EAC’s) can also offer you high-quality clean air over the typical cheap air conditioner and furnace filters on the market today. Clean the air in your home and breathe easier. (more…)
About Chilled Water Systems HVAC Hydronics - Chilled water systems are mainly used in large commercial HVAC air conditioning systems and industrial cooling applications although there are some residential and light commercial HVAC chilled water systems in use. Chilled water systems are popular because they use water as a refrigerant. Water is far less expensive than refrigerants. This makes them cost-effective, especially in commercial HVAC air conditioning applications. (more…)
Condensing Unit Too Close to House - This condensing unit was too close to the house to effectively reject heat. It was a bad HVAC condensing unit installation job by the HVAC installers. A mechanical inspector rejected the final permit until the condensing unit was correctly installed.
It is recommended that condensing units have at least 2 feet of space so that they can effectively reject heat. It needs space to breathe and pull air into the coils so that there is a proper heat exchange taking place when it is running. On this air conditioner condensing unit there are four sides to the unit.
By installing the air conditioner condenser too close to the house the installer effectively reduced the capacity of this unit by nearly one-fourth which will cause problems with the unit in the way of higher head pressures and that will cost the homeowner more money in the long run.
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…)
Air Conditioner Squirrel Cage Blower | HVAC blower motors move the air through the system. The blower motor is sized based on the amount of air flow necessary for the system. This blower motor is the supply fan for the supply air in a large commercial York AHU. An AC and heatingforced air system is sized based on load. The load factors include heat loss and heat gain, number of people in the building, types of rooms served, factoring in heat produced by equipment such as computers and other heat producing equipment.

Air Conditioning Service Repair - No matter what name brand (York, Trane, Carrier, Goodman, Lennox, Rheem) of air conditioning and/or heating unit you purchase some time or the other you will need to have that air conditioning and heating equipment checked for a problem and repaired. Even if you have regular air conditioning maintenance done. While there are air conditioning and heating manufacturers that engineer quality into their air conditioning and heating equipment, that equipment is prone to breakdown simply because it is a mechanical/electrical device and will need repair sometime throughout its useful life.

HVAC Mechanical Code Overview - Many people unfamiliar with air conditioning and heating do not know that the mechanical code regulates air conditioning and heating system installation in many municipalities. (more…)
HVAC Tip - Carbon monoxide detectors are important to own for those people who burn fossil fuels for heat. Carbon monoxide is a flammable, colorless, odorless, tasteless toxic gas produced during incomplete combustion of fuel - Natural Gas, Oil, Coal, Wood, Kerosene, etc. Someone suffering from carbon monoxide poisoning generally has severe headaches, nausea, and sinus problems. These symptoms generally begin with mild effects and people usually remain unaware of what the exact problems are until, sometimes, it is too late. How many cracked heat exchangers or faulty furnaces are out there that no one knows anything about except a slight headache and nausea? Don't take any chances, get your carbon monoxide detector and call your local heating and air conditioning company for a heater inspection today. Read more on this subject on the Furnace Page.
