As an HVAC expert with years of experience, I have helped countless homeowners choose the perfect AC unit for their 1200 sq ft house. It can be a daunting task, especially if you are not familiar with the terminology and technicalities involved. But don't worry, I am here to guide you through the process and help you make an informed decision. First, let's understand the basic parameters that determine the size of an AC unit. A portable or window air conditioner designed for one room is usually measured in BTUs (British Thermal Units), while a whole-house air conditioner is measured in tons.
For a 1200 sq ft house, you would need a two-ton unit. Similarly, a 2400 sq ft house would require a four-ton unit, and a 2000 sq ft house would need around five tons of air conditioning. Now, you might be wondering how to determine the exact size of AC unit your house needs. While an HVAC professional or HVAC installation company can provide you with an accurate calculation, there are a few factors that you can consider to get a rough estimate.
Consider Your Climate
The climate of your region plays a significant role in determining the size of your AC unit. If you live in a hot and humid area, your AC unit will have to work harder to cool your house.In such cases, it's best to opt for a slightly larger unit to ensure efficient cooling.
Insulation and Energy Efficiency
The insulation of your house also affects the size of your AC unit. A well-insulated house will require a smaller unit as it will retain cool air better. On the other hand, if your house has poor insulation, you might need a larger unit to compensate for the loss of cool air. Additionally, consider the energy efficiency of your house. If you have energy-efficient windows and doors, your AC unit won't have to work as hard, and you can opt for a smaller unit.Number of Occupants
The number of people living in your house also impacts the size of your AC unit.If you have a large family or frequently host guests, your AC unit will have to work harder to cool the house. In such cases, it's best to opt for a larger unit to ensure everyone stays comfortable.
Other Factors to Consider
Apart from the above factors, there are a few other things that can affect the size of your AC unit. These include the number of windows and doors in your house, the direction your house faces, and the presence of heat-generating appliances like ovens and dryers. Now that you have a better understanding of the factors that determine the size of an AC unit, let's look at some common mistakes homeowners make when choosing an AC unit for their 1200 sq ft house.Common Mistakes to Avoid
- Choosing a Unit Based on Price: Many homeowners make the mistake of choosing an AC unit solely based on its price. While it's essential to consider your budget, don't compromise on the size and quality of the unit.
A smaller unit might be cheaper, but it won't be able to cool your house efficiently.
- Ignoring Professional Help: As an HVAC expert, I highly recommend seeking professional help when choosing an AC unit. They have the knowledge and experience to accurately calculate the size of the unit your house needs.
- Not Considering Future Needs: When investing in an AC unit, it's essential to consider your future needs. If you plan on expanding your house or adding more rooms, you might need a larger unit in the future. It's best to invest in a slightly larger unit now to avoid any inconvenience later on.
It's always best to seek professional help and avoid making common mistakes that can lead to inefficient cooling and higher energy bills. I hope this article has provided you with valuable insights and will help you make an informed decision when investing in an AC unit for your house.
