in order for them to work. A place in which to drain any condensate that will develop when running on the cooling mode. You can purchase mini-pumps to send the condensate up and out but they are expensive. So be sure to mount the indoor part above the outside soil level and on an outside wall.

Do your homework on manufactures. While their are many brands, warranty service is another issue all together. I will not name companies or brands, but there are only two systems I will sell my clients because of difficulty in getting repair parts for the others. Remember you get exactly what you pay for.

There are systems made now that have picture frames covering the indoor part of the system. Unique idea, but steer clear of them. I have removed a few of these systems in the past because of part issues not available in my area. They also have poor air flow. They do not push the air out across the room and only blow it out sideways. If the room is larger you want the air to move around to get the best effect from them.

On cost, these systems cost more then a new system for central AC does. equipment alone. Your not really saving much with mini-split other then to not having to install ducts in the rooms which is often difficult with head room in a basement.

Good luck.

Yes, it has become a issue over the last few years. We have seen an up-tick in the amount of theft in all copper coming out of home. With the coil of a household A/C unit having 30 to 100 lbs of copper and 5 to 10 lbs of lead it has been a target.

and fall, to ensure your system is prepared for months with extreme highs or lows in temperature. Regular tune-ups will extend the life of your equipment and improve efficiency, reducing run time and waste. Not to mention, with the money that you will be saving in utilities each month, the tune-ups will pay for themselves. Great for the environment and your wallet!

Tune-ups are universal. Everyone needs them every year. Other recommendations will vary based on your home and situation. If you plan on staying in your house for years, it might make sense to renovate your duct system, replace your cooling system, or replace your heating system.

control for over 10 years. As a commercial technology it works as advertised. As a residential technology it does not because by law, all residential meters measure real power only. There is no basis in the physics for this to work on a residential system nor does it stand up to any measurements I have performed. I do not dispute that there are those who claim savings based on the electric bill, but I also note that historical compairisons of electric bills show variations as high as +/- 25% year over year. And not to paint anyone with a brush, but I have seen a great deal of shilling in boards like this (sorry).
