Getting a new HVAC system installed is a big job since there are several parts to the system. It could take a few days to get the job done, depending on the size of your house. An HVAC system is composed of a furnace, ducts, thermostat, and an air conditioner. Here's a look at having each of the components installed:
The Air Conditioner
The air conditioner is usually a split system that has an air handler inside your home and a condenser outside. One consideration is where the installer will put the outdoor unit. It often rests on a small concrete pad near the electrical panel. The HVAC contractor has to consider the best place for the condenser so the noise doesn't keep you awake at night and so it isn't in full sun all day long, if possible. The condenser and air handler need to connect to each other through refrigerant lines, and the air handler needs to drain condensation outside, so this part of the installation usually involves drilling some small holes in the side of your house.
HVAC ducts are often placed in the attic so they are out of the way. When the contractor calculates the right size for your HVAC unit, the size for the ducts is calculated as well. Proper installation of the ducts is important so no air leaks into the attic. Sometimes, blown insulation can be placed over the ducts to provide some insulation for them, so if you plan to get new attic insulation as part of your renovation you may want to install the ducts first.
A thermostat is an important part of an HVAC installation, and you have a lot of variety when you pick out the thermostat. A basic programmable thermostat is all you need, but if you're moving toward a smart home then you should look into the smart thermostats that are available. You can program these as well, but they also detect your presence and can adjust the temperature automatically based on different factors. A smart thermostat could help save on your power bills, especially when you combine it with a new energy-efficient HVAC.
Replacing your entire HVAC system at once keeps everything aging at the same rate. That's why it's often good to replace an old furnace at the same time you replace an old air conditioner. This also ensures the ducts are the right size for both a new furnace and AC system. One choice you have with a new furnace is if you want electric or gas. That may depend on if you already have a gas connection, since running a new gas line or installing a propane tank will add to the cost. Another consideration with a new furnace is where to place it. A basement is often a good location, but if you don't have a basement then the laundry room or a converted closet might be another option as long as there is enough ventilation to the outside.
