Air Conditioner Condensation Problems - It is important for air conditioning preventive maintenance to be performed on your system to avoid problems. Condensation water leaking near the air handling unit can be avoided with proper air conditioning repair and preventive maintenance. Normally this is a very simple problem that can be fixed in less than 30 minutes. Here is a list of what can cause water around the outside of the air conditioning air handler unit. (more…)
Bad Ductwork - Ductwork is necessary to deliver the air throughout the HVAC system. It is important that the system has integrity with no leaks. Ductwork is made of different materials. Duct systems also have different construction methods which hold the ductwork together.
Pictured above is an old ductwork system (which needs to be replaced) made of duct board, which is a rigid fiberglass board, metal, and flex ductwork. The duct board is cut to size from the ductwork sizing requirements for the tonnage and taped together with special duct tape. For the branches coming off the duct board trunk, metal collars are inserted into holes cut to size in the duct board. Flex ductwork is attached to the metal collars for the branch ductwork. (more…)
Leaking Air Handler- Air Leaks - Dear Richard… my partner and I moved into a brand new mill conversion/rehab condo last year that we absolutely love, but after the summer was over, I went into the utility closet (where the air handler/gas furnace are) and noticed that there was copper corrosion crust/rust that had run down from the air handler (not sure from where, but somewhere fairly high up on the AHU). It had dried up, and didn’t seem to be enough to run down the sides of the burner even–no streaks). (more…)
HVAC Duct Systems - Ductwork systems channel the air to the spaces where it is needed from the air handler. HVAC duct systems also will pull the air from the space and channels it back to the air handler where it needs to be conditioned. In some commercial applications, the area above the ceiling is considered the return duct. All the return air is channeled back to the air handler through the plenum where it is conditioned in the air handler. Part of the conditioning process is the air being passed through an air filter and then an exchanger like a coil or heat exchanger. (more…)
Ductwork Integrity and Insulation - So you are having a new HVAC system installed and you selected a system that is high efficiency and you want to get the most out of it. Have you looked at or has the HVAC contractor looked at the ductwork and determined if it is good enough for the high-efficiency system.
A good HVAC contractor would look at the ductwork to make sure it is adequate and sized properly for the new system. This is often done as the HVAC contractor wants to ensure that the new system is properly matched to the HVAC ductwork lest the system not work as it should. Beyond that, the most overlooked part of the ductwork is the ductwork integrity.
HVAC Tip - Some people refer to refrigerant as Freon. So when something is wrong with their HVAC system they say, “I have a Freon leak”. Freon is a name trademarked by Dupont for R-22. R-22 is being phased out because it contains chlorine. While Freon will soon be a thing of the past, the name Freon has found its way in our lexicon as a reference to refrigerant, any type of refrigerant.
