Big Air Conditioners Are Not Always Better in San Diego
Freezing cold? Sweating? Boiling?
None of these conditions are bearable, and you should not have to live with them. Your home is your refuge, after all, and you bought the air conditioning unit to help you relax there. While plumbers and home builders can make mistakes, homeowner misconceptions about air conditioning systems also lead to long-term air quality disastisfactions. Get clear on the truth behind your air conditioning system so you can help guide your San Diego plumbing contractor into the best decision for your home.
First: Bigger is NOT Better
Many San Diego former renters have sweated through August, September and even October with no air conditioning. While our really hot periods are short-term, they can be debilitating, forcing family members to sleep downstairs, at friends’ homes and even hotels.
The minute these brave people buy a home, their former cool air deprivation drives them to buy big. Ethical San Diego plumbing contractors will and home remodeling magazines will tell you that bigger is not better. Even Energy Star, the EPA’s program for energy efficiency, recognizes that too many “buy an air conditioner that is too large, thinking it will provide better cooling.”
Here are a few reasons you must simply buy the right sized air conditioner for your home:
- big air conditioners with a lot of power blow cold air through a small home quickly. While this sounds good, it really means a big system starts and stops constantly throughout the day, giving you poor electricity mileage and energy efficiency.
- a large air conditioner requires larger ducts. Do the ducts on the home handle the volume of air the furnace forces through it? Also, it will require a larger furnace. If it has neither, it will be very noisy.
- The starting and stopping of a large air conditioner is hard on the environment. Once you start running an AC, you want it to keep running for a while.
- A smaller air conditioner running more consistently removes moisture from the air more efficiently.
- A large air conditioner can seem to be running properly just from its power. If there are duct leaks, poor airflow across coils, inadequate charge, they may remain masked for months, leading to high energy usage, poor air quality and pollution.
How to Properly Measure for Air Conditioner Size
EnergyStar makes clear that determining how many BTUs per hour requires more than the overall house square footage. In general, 1,000 to 1,200 square feet requires 21,000 BTUs and 2,500 square feet needs 34,000 BTUs. You can extrapolate between those numbers to determine your home’s air conditioning power needs.
Still, tweak your numbers if certain conditions exist. The above guidelines should be:
- increased by 10% if the rooms are very sunny
- decreased by 10% if they are shady
- increased by 600 BTUs per person over two occupants
- increased by 4,000 BTUs if installed near a kitchen.
- increased by 10 – 20% if home is in humid area (by the beach!)
