If properly maintained most air conditioners can last 12 to 15 years but they are expected to develop problems in the 8 to 10 year range mostly because of neglect, no or limited maintenance. To achieve the most from your Air conditioner, check your filters monthly and have a licensed air conditioning technician check and clean your system twice per year in the Spring and again in the Fall. Doing this can expand the life of your system and keep you from paying large repair bills along the way.
Keep plants and vegetation at least two or three feet away from the unit to insure it get proper air flow. Remove all leaves or debris that my collect in the unit and hose it down when it is turned off to keep it clean. If you keep the outside unit clean it will insure its ability to exhaust the heat it creates and will run more efficiently.
YES! If your air conditioning unit is constantly running, does not shut off or you feel warm air blowing from the vents you should call a licensed air conditioning technician. Other signs are if you hear strange noises or smells and if you have an increase in your utility bill that is higher than normal. Also, if you see water running out of the emergency drain located somewhere on the outside wall of your home.
Yes, if you see yourself having major repair bills it may be less expensive to go ahead and replace than to continue repairing. The older the unit gets it will start showing more signs of trouble and more visits from the repair technician and the units efficiency will go down and your electric bills will go up. If you are in this situation it is most likely time to get a professional opinion on replacing the unit.
The answer is usually yes. The reason is, you don’t want a mismatched system. I have seen it work on occasion but a mismatched system will end up running much less efficient and cost more money to operate on a monthly basis. Also the new system may not run on the same type of Freon. It is always better to replace both inside and outside units with compatible equipment for best performance and efficiency.
Yes it Will! An air conditioner unit that is old can run up your electricity bills very quickly. It is usually running about 50% to 70 % less efficient than most basic new systems. With today’s new high seer energy efficient systems, they will use a lot less electricity and keep you cooler at a much cheaper cost. I have seen cases where the electricity bills have been reduced by 30% to 40% and higher!
No! You have heard the saying in our area, “it’s not about the heat, it’s about the humidity. You’re a/c unit needs to be sized correctly based on the square footage of your home so unless it was sized wrong to begin with you do not need to up size to a larger system. Too large of a system can actually not remove the humidity properly from your home and not run as efficient.
You should have a licensed air conditioning technician check you’re a/c unit in the spring and also check your heating system in the fall before we start getting cooler and before you turn on the furnace. The professional can check your refrigerant level and clean the evaporator coils and check and perform both an a/c and heating check of your system. Having your system checked by a licensed, trained a/c professional can save you money on potential much larger repair bills.
SEER stands for Seasonal Energy Efficient Ratio and is the ratio of the amount of cooling produced (BTU) divided by the amount of electricity (watts) used. A higher SEER rating on the equipment means greater energy efficiency and is cheaper to operate. Most ac equipment today can range from a 13 to 21 seer.
There can be a number of reasons why one room is cooler than other rooms in your home. Here are a few:
- Could be a heat load issue from windows.
- Clogged system or improperly installed duct system.
- Improper zoning with single system and two story home.
There can be a number of reasons and will require a professional licensed A/C technician to inspect and analyze for the specific problem.
The normal temperature setting in the summer is 74 to 76 degrees and in the winter for heating is between 68 and 72 degrees. Try and set your thermostat to the highest setting in the summer to keep you cool and the lowest in the winter to keep you warm. By doing this you will maximize your energy savings. The rule of thumb is for one degree of temperature change is equal to about 1% in energy savings.
