Air Conditioners: From Maintenance to Buying New

Central air conditioner units

Staying cool is on the top of most people’s minds during the hot summer months. But what if your air conditioner isn’t working properly, or you don’t have one at all? Whether your existing AC is in need of upkeep or you’re in the market for a new one, read on for some helpful tips to keep you cool!

Maintain AC Units for Maximum Performance

By performing regular maintenance on your air conditioner, you will not only extend the life of the unit, but your home will remain at a comfortable temperature without an uncomfortably high energy bill.

How to Maintain Window, Portable, and Wall AC Units

If you have window units, the most important maintenance step is to change the air filter regularly. Most window units have a simple filter in the front grill area. Clean it once a month during cooling season and be sure to replace it when it has any holes or just appears worn. Also, be sure to clean the air conditioner properly by vacuuming around it to remove any dust and dirt that will clog up the unit and cause it to not work properly.

During the off season, if possible, take the unit out of the window and store in a dry location. If you must keep the unit in the window, be sure to cover the part that is exposed to the outside.

How to Maintain Central AC Units

For central air conditioning units, the single best way to keep yours working properly year after year is to have it serviced annually by a trained HVAC professional. They will take care of the many items related to maintaining the unit and be able to perform any necessary repairs or “tune-ups”.

Beyond that, be sure to keep the unit outside free from leaves and debris by raking around it and spraying off the unit with water. And make sure, above all, to change the air filter inside the house every few months or more.

    I recently read in a leading consumer magazine, the the portable type air conditioners are next to useless. Let the buyer beware. Just sayin!

    This is so useful, thank you! My air conditioner is in need of repair probably due to overuse this summer. It is an older unit and it is about time anyways for a replacement. However, I am so glad that it lasted throughout the summer. I would really like to get another one that is long lasting. Which brand is known for being the most durable?

    Inquiring on the average cost to have my 18,000 btu Ramsond a/c wall unit cleaned (has some mold on the plate). I would appreciate knowing the cost I will be expecting to pay for this service.

    I have central A/C but its only one zone. Upstairs I have 3 bedrooms and its always warmer. I hate to waste the central air at night since I just need it to cool upstairs. I was thinking of getting a window air conditioner, but I don’t think it will cool one of the bedrooms because of where it is located. It can cool off 2. So that would mean I would have to get another small a/c for that 3rd bedroom. Would it be cost-effective to buy one average size a/c and one small a/c for night time only instead of runnning our central a/c? Plus I think it will cool it better since its a one zone and upstairs is always warmer then downstairs.

    Dear Sir,
    I am setting up a motor home and wish to place a window wall air conditioner inside the bus, the rear of the unit would extend to the out side of the bus wall and the remainder or the unit would be in an inclosure with four inches on either side of the unit, is this exceptable for air flow to the unit or not, I am not sure if a unit needs to have air flow around it or only on the rear, any help would be appreciated.
    thanks
    Michael.

    Would window air-conditioners installed on its side instead of its designed upright position due to window space restrictions function properly or not?

    I have seen a system advertised on the Wether Channel that dosen’t require duct work. Right now we are using 2 window air conditioners & they work fine, but, I also know they are now as cost effective as centeral air. We are also getting older & putting them in & taking them out every season can be back breaking. Please let me know how well these work & where I can find a dealer in my area. We live in St. Pau MN.

    What types of house insulation are availble and illustrate to pros and cons of each?



  • John Cannamela Says:

    A few other things to remember.
    The units seer rating may only be as good as the building its installed in.If the envelope is less than to be desired than the hi seer unit will not pay back as quickly as stated.It is as important to have the home checked for window,insulation and air infiltration.You may want to spend the money on insulation instead of the hier seer ,the cost offset could be the same or in most older homes better to insulate in the long run.
