When it is time to replace your AC unit in your home, you should avoid rushing into the purchase of one. There are things you need to be aware of and several decisions to be made. The following are three things you need to think about.

Buying an AC unit that fits your home

Air conditioning systems today are more efficient than ever before, but the savings that you can realize with a modern design will be wasted if you buy the wrong size unit. If the unit is too small for your home, it will be working hard to keep your home cool and will use too much power. A larger unit will easily keep your home cool, but if it is larger than you need, you are spending too much money up front to purchase it. The solution is to take the guess work out of the process. An HVAC contractor can run a load calculation to determine the optimal size unit for your home.

Buy your new machine directly from a dealer

Often, a homeowner will buy their new AC unit from the contractor that installs the system, but this is not always ideal. Once you know the exact requirements for your optimal AC unit, you can shop around for the best deal. When you buy from a contractor, you are buying from a middleman, and the brand name selection may be limited. Shopping around will enable you to get a good price. However, you should still get a quote from the contractor you plan on using for installation because their prices can sometimes be competitive.

Switching to a ground level unit

If your old AC unit is on your roof, you might want to think about switching to a ground unit. An AC unit on the ground is not subject to higher temperatures than those on a roof. In addition, they have a tendency to last longer and require less maintenance because they are protected better on the ground. If you are considering switching to a ground unit, make sure an HVAC service technician is aware of this. You may be able to buy a smaller unit if you are installing it on the ground, and the installation cost may be different as well.

Whatever you decide, you shouldn't rush into buying your next AC system. Your new AC system will last you for many years to come, so you need to make sure you get the unit that is best for your home and at a price that is acceptable. And don't hesitate to get help from an HVAC contractor. Installation is only one of their services. They can provide valuable consultation service as well.
