Effects of Low Refrigerant in Your Air Conditioner

Monday, June 29th, 2015

An air conditioning system is based around the use of refrigerant: a chemical compound that makes the whole process possible. Your system first compresses the refrigerant and shifts it from a gaseous to a liquid state (which releases heat into the surrounding atmosphere), then moves it to an evaporator coil, where it is shifted back into a gas (which pulls heat in from the surrounding atmosphere). That cool air is then moved into your home while the gaseous refrigerant returns to the start of the cycle to begin it anew. Contrary to popular belief, refrigerant isn’t consumed: it needs to stay at set levels determined by your make and model of air conditioner in order for the system to work. But when leaks spring up or refrigerant levels otherwise run low, it can have a bad effect on your air conditioner: the last thing you need in the middle of another hot Austin, TX summer.

Repairs a Ductless Heating System May Need

Monday, January 12th, 2015

Ductless systems are a unique and effective way to heat your home. Like all heating systems, however, they occasionally run into issues. Ductless heating systems are not combustion based, so a lot of the problems they experience are very different from your standard boiler or furnace problems. Let’s take a deeper look at the repairs a ductless heating system may need, and how you can identify them.

Refrigerant Leaks

Refrigerant is a vital part of a ductless heating system’s operation. When the heating system turns on, the outside unit uses an evaporator coil to convert refrigerant inside the coil into gas. This turns the refrigerant into a heat sink, leeching heat out of the air around the unit and into the coil. The refrigerant then carries the thermal energy through the refrigerant line and into the indoor unit, which converts the refrigerant back into a liquid. This releases the thermal energy so that it can heat the room.

Refrigerant is not consumed by the ductless heating system. Instead, it is recycled each time the heating is turned on. A refrigerant leak is a major problem because it drains refrigerant from the system, making it unable to transport heat into the home. If you notice any pooling or dripping liquid around your ductless unit, call a professional right away.

Broken Defrost Cycle

When the ductless heating system’s outdoor unit evaporates refrigerant to draw in heat, it also creates condensation on the coil itself. The combination of condensation on the coil and a drop in the surrounding air temperature can cause ice to begin forming on the unit. All ductless heating systems are designed with a defrost cycle, to melt the ice off of the unit. If the defrost cycle isn’t working, however, ice can build up until it covers the entire outdoor unit. This cripples the whole system by depriving it of the air that it needs to siphon thermal energy from.
