Tips for Installing Central Air in an Older Home
The hotter the weather, the more we think about air conditioning. Many new homes are built with central AC already installed, but many of us live in older homes that simply aren’t built for a ductwork installation for central AC.
However, no longer does living in an older home mean you can’t have a central air conditioning system. Nowadays, thanks to some spectacular new technology from Mitsubishi, there are some great options for retrofitting AC systems both with and without ductwork.
5 ways you can add central air conditioning to your older home
- You already have forced-air heating with ductwork throughout the house. Adding AC is simple: install a cooling coil on the top of your existing furnace and tie it into a condenser outside.
- You heat your home with a hot-water boiler, and have a newer home with 2×6 wall studs that can accommodate ductwork in the stud pockets. To add central air, you need an inside air handler, ductwork, and an outside condenser. Ductwork can be run to registers in the basement ceiling and the attic floor, thereby cooling both the first and second floors.
- You heat your home with a hot-water boiler, but it’s an older home with horsehair-plaster walls and no stud pockets. You can cool the first floor by installing an air handler in the basement, and the second floor by placing an air handler in the attic. You will also need a condenser outside.
- Your house has no space for traditional metal ductwork but could accommodate high-velocity flex tubing. The smaller size of the tubing makes this an excellent choice when retrofitting central air conditioning in older homes. As well as the tubing, you’ll need an outside condenser and an inside high-velocity air handler.
- You don’t want to take on the cost of installing ductwork or high-velocity tubing. You can still have efficient air conditioning. You can fit a wall-mounted ductless split cooling/heat pump, such as the “Mitsubishi.” The unit can be hung on any internal or external wall as long as it can be connected, via refrigerant lines, to an outside condenser. Multiple units can be linked to one outside condenser, which requires 220v electricity. This is an excellent, relatively inexpensive option for bringing comfort to your home. The bonus is that in spring and fall, when outside temperatures are cool but not freezing, the units can heat your home as much as 60% more efficiently than your traditional heating system!
Want to stay cool next summer? Don’t wait until next July; think about installing central AC today. Doing so could even save you money on your heating bill once the temperatures drop this fall!
