AC System Installation: Top Mistakes to Avoid


When you’re looking at a new AC system installation , there are many things to consider. How much will it cost? Does the room have enough space for the unit? What kind of ductwork do I need? There are so many questions that it can be overwhelming. Here are some mistakes that people make when installing an AC unit:

Not enough planning

Planning is the key to success. It’s important for every aspect of life and business, but especially when it comes to installing an AC system. If you don’t plan ahead, you could end up spending more money than necessary. For example:

  • You might not have enough cash on hand for your new AC installation because you didn’t budget appropriately;
  • The contractor may run into a problem during installation that requires extra time or materials; or
  • Your house could be located in an area where winter weather makes regular maintenance difficult (like frozen pipes).

Not making sure the room is centered correctly

When an HVAC service Orange County Ca system is installed, the room should be centered on it. If you’re installing a new unit and have a space that’s not centered, then there are several ways to get it so:

  • Make sure your ductwork is in the center of your house. If you don’t have any ducts going through your walls (and instead rely on open grilles), then make sure they are all facing outwards from either side of where you need to put the machine.
  • Position electrical panels so that they line up with each other as well as with anything else connected to them (such as fans). Check with an electrician or plumber if this isn’t clear enough!
  • Position plumbing lines so they aren’t touching any pipes/valves/etc., but also don’t obstruct anything else either accidentally or intentionally by making sure everything fits inside its designated area correctly before putting things together.”

Not getting a permit correctly

  • Not getting a permit correctly
  • Getting an incorrect permit
  • Failing to pay for the correct permit

Not measuring correctly

  • Measure twice. The first time you measure, take a basic measurement from the wall and then check to see if it’s correct. If it is, go ahead and move on to measuring in the correct direction.
  • Measure for height and width first. After taking your initial measurements of length and depth, add up all of those numbers to get an idea of how much space you will need for each part of your system—including any pipes or ducts that may need to be installed underneath furniture or other items around your home (or office). Once you have this information handy, pull out a piece of paper with dimensions listed so that they’re easy enough for anyone else who needs them too; this way everyone can follow along easily as well!

It’s better to be safe than sorry.

If you want to be sure that the AC system will work well and last long, it’s better to hire a professional. It takes experience and knowledge to install an air conditioning system properly. It’s also important not to make mistakes when installing an AC system because they can cause serious problems later on in the future.

As you can see, there are a lot of things that go into installing your AC system. You really want to make sure the room is centered and that you have enough space around it so that the ducts don’t obstruct traffic in other areas of your home or office. You also want to make sure that everything is running smoothly before moving on to anything else!
