What Is An HVAC Start Capacitor, Why Does Your AC Need It, And What Malfunctions Can Thwart Your System?

A central air conditioner contains two main segments, the outdoors condensing unit and indoors air handler, and each segment contains a variety of parts that work together to move a chemical fuel through to provide the cooling your home needs. The process starts at the thermostat, which sends a signal to the condensing unit and powers up the compressor. The compressor squeezes out the refrigerant gas that will move through the whole system in various phases.

The compressor depends on a couple of capacitors, which include the start capacitor, to function properly and reliably. What is an HVAC start capacitor, why does your air conditioner need it, and how can the part malfunction and thwart your system?

Start Capacitor Use and Function

What Is An HVAC Condensate Pump, Why Does Your AC Need It, And What Pump Malfunctions Can Thwart Your System?

The air handler portion of your central air conditioner is inside your home, normally in the furnace, and contains the parts that make up the final stages of the cooling cycle. The parts include the evaporator coils, which receive a liquid refrigerant from the outside condensing unit and perform a phase change that both makes the refrigerant a gas and makes the surface of the coils cold. The cold coils chill the circulating ambient air that is then passed back into your home.

The evaporator coils have some correlated parts important to making the system work effectively and safely. One of those parts is the condensate pump, which is located in the drain tray at the bottom of some air conditioners.

Condensate Pump Function

The evaporator coils become moist during the phase change that ultimately cools the coils. That moisture forms condensate, which needs a place to go since a …

Keeping Feathered Friends Away From Your Air Conditioning Unit

If you use an air conditioning unit to cool yourself off during warmer temperatures, you most likely want to keep the appliance in good working order to avoid unnecessary downtime when the unit is needed most. One hazard to an air conditioner is when birds use it as a nesting place. Nests built on an air conditioner can lead to inadequate airflow due to obstructions caused by twigs and grass. Bacteria can also become present within the unit, leading to compromised airflow into the home. Here are some tips you can use to ensure feathered creatures do not take up residence on your unit.

Cover The Unit When Not In Use

It is important to take the time to use an appropriate air conditioner cover during its off-season. This will not only keep roosting birds away from the unit, but will also protect it from other pest invasions as well. A cover will additionally provide protection against ice …

Should You Consider A Hybrid Heating System?

Energy-efficiency is an important trend today among homeowners, not only because energy-efficiency is better for the environment but because it’s also better for your wallet. If you’re getting ready to replace your furnace this fall before the cold weather starts, you may want to consider a hybrid model. These are some things to consider before you start.

Do you have a somewhat unpredictable climate?

If the most reliable thing about your weather is that it will probably change in the next hour or two, a hybrid furnace system with a dual-speed fan could be a big energy and money saver. A hybrid heating system can be set to handle the cooler temperatures that come with an elongated autumn or mild winter weather using an electric heat pump. Once the temperature dips closer to freezing, you can switch the unit to propane. This lets you conserve the expensive propane for the …

Four Problems That Arise When You Install an Oversized Furnace

A good HVAC technician will recommend a furnace that’s correctly sized for your home. However, some homeowners demand a larger furnace because they (falsely) believe it will keep their home even warmer or will operate more efficiently. This is just not a good idea. If your HVAC contractor recommends a furnace of a certain size, trust that that is the size you need. Installing a furnace that’s too large can cause the following issues.

High Energy Bills

A furnace that is too big for your home will end up turning on and off very often. As soon as it gets burning in its peak-efficiency range, it will be time for it to turn off again. This short-cycling requires a lot more energy, so your utility bills are likely to shoot up. Once the too-large furnace is installed, no amount of scrimping and insulation will bring your bills back down to …
