An incorrectly sized unit is either working too hard to keep your house cool or will not be able to perform the task at all, which will cost you money. A qualified HVAC contractor will help you determine the correct size unit for your home.

There are many variables that determine the size of your AC unit. Some of these factors are obvious, such as the square footage. Other aspects aren’t as evident, like the amount of heat-generating technology or appliances in your home. These items produce a lot heat, which your AC must handle.

You should also consider the climate in your area and what type of materials you used. Certain materials absorb and reflect heat differently, which could impact the size of your air conditioning unit. Also, you should think about how well your home is insulated, as well as the number of windows and doors you have. Some of these are designed to let lots of heat in and may require more of an AC unit.

The amount of windows in your home and the orientation of them towards the sun could affect the quantity of heat transferred to your home. The level of insulation in your home will also have an impact. Insulation is especially important since it will prevent cold air from escaping your home at a rapid rate.

For instance, those who tend to open their windows and doors will have to use their AC more frequently than a household that keeps the doors and windows closed. You may also consider tax credits for models that use less energy. These discounts can reduce the price of a new air conditioner. Furthermore, a modern model is likely to be more energy efficient than an older model.

This can also be caused by holes or cracks in the ducts that need to be repaired as soon as possible.

If you hear a hissing sound emanating from your air conditioner, it’s because of a leak in the refrigerant. The hissing sound occurs when the refrigerant flows from the high pressure side of the system to the lower pressure side, via the metering device, which has a tiny orifice. While the hissing sound isn’t an issue however, it is advisable to have it looked at by an HVAC technician just in case. This problem can be expensive to fix, so it’s best not to ignore it.

You can also connect the fins and coils to keep the outdoor unit free of dirt. Just be sure to use a standard garden hose, not a pressure washer that could cause damage to the unit’s components.

Certain AC specialists provide maintenance contracts that buy customers twice-yearly maintenance inspections and reduced costs on parts and accessories. They can be a great option for those who do not have time to maintain your own equipment or if you’d like peace of mind knowing that a trained technician is monitoring your system.
