What to know before getting an HVAC designer or contractor
There's a lot to consider when getting an HVAC contractor or designer, so if you're looking to take the plunge, here are some key points to keep in mind.
Make sure you know what type of system you need – If you only need heating or cooling, for example, your search might be narrowed down considerably. And if your home is large or has a complex layout, it might be worth spending extra money on a contractor with experience designing systems specifically for homes.
Get estimates – It's important to get multiple estimates from different professionals before making a commitment. Not all contractors are created equal, and some may charge more than others for the same services. You can also compare costs online.
Get references – Ask your friends, neighbors, and other people who have used contractors in the past for referrals. They'll be able to give you a good idea of who to go with and what to expect from the process.
