Why is it that every advancement and improvement seem to make things more complicated? Not to wax too nostalgic but doesn’t if feel like the ‘good old days’ of shopping and buying are long gone? That’s true even with air conditioning systems, a non-negotiable item for most residents in Drexel Heights, Arizona. The winters can be cold and dry, but those warm months – especially the 4 months of sweltering, 100+ degree heat from May through September – are almost unlivable without some kind of central air system.
However, just because you need something, doesn’t mean you understand all the factors that go into buying it. That’s why we’re hoping to simply the process and answer a few questions for those AC Unit shoppers in Drexel Heights.
Even if you’ve got a reliable HVAC contractor helping you out, as with any purchase, the more you know, the better decision you can make. And, we won’t kid you – a home HVAC replacement can be pricey! So, let’s get stared.
What Do You Really Need?
Every home is different from how much space you need to cool to how much room you have for your AC Unit, and whether it should be all indoors or a split system with part of it located outside. Check out our article on AC Options to familiarize yourself with the basics.
If you have an existing system that doesn’t seem to be doing its job, you may just need some basic maintenance. But if your central air system is no longer up to the job, then it’s time to start shopping.
Here are a few terms that you need to understand:
SEER – Seasonal Energy Efficiency Ratio. This is a rating that measures how energy efficient your AC unit is – much like the MPG (miles per gallon) in your car – so it’s an objective rating. The minimum rating is 13 and the maximum is 21. The higher the rating, the more energy efficient…and that can mean savings on your utility bill.
BTU – British Thermal Units. This is a term that lets you know how much cooling power the unit offers. Without getting too technical, it means the amount of energy needed to raise one foot of water 1-degree Fahrenheit. The larger your room (or space you need to coo) the more BTUs you will need. The good news is that AC units make this information easy to find in the product specifications.
Evaporator and Condenser Coils – These coils do the work of cooling your home, but unlike your furnace heating up air and blowing it through ductwork, your evaporator and condenser coils circulate coolant (refrigerant) to absorb heat in the air and carry it outdoors. They continue to remove heat until the temperature set on your thermostat is reached.
Have you Had Enough?
Knowledge is power, especially in the buying process, but sometimes too much is too much. If all the terms and figuring out the best central air system for your home makes you frustrated, then ask for help!
