Heating and cooling units can be a great thing, but what do you do when they start to fail? To ward off disaster, spend time getting to know the subject before something goes awry. This article is intended to help conscientious homeowners learn how to hire the help they need.
Before calling for help, know the system you have. Look for the maintenance history and brand and model. This will ensure that you can give your new contractor all the information they need.
Before an HVAC expert comes to your home to do any repair work, walk around the home and check out the temps in every room. While you are walking through the house, gauge which rooms are the coolest and which are the warmest. This information will help the contractor determine where the problem is and how to fix it.
It is important to have some knowledge of your present system and needs before calling a contractor. It will be hard for a contractor to give you a price estimate over the phone if they have not seen your current system. If you do not know what you want, the process can become tedious, especially over the phone. So be aware of this information ahead of time.
Fall is a hard time on HVAC units. Clean outdoor units often to remove leaves. When blockages restrict the flow of air to the fan, you could end up with serious issues on your hands.
If the condenser fan has oil parts, then you need to lubricate it at least once per year. These are usually covered with rubber or metal caps. Choose an oil graded SAE 20, it is non-detergent and lightweight. Place about 10 drops into each of the ports, taking care that it does not overfill.
Nobody ever wants their heating and/or cooling systems to go out when it is really hot or really cold. You must have this knowledge in advance though. Use these suggestions to increase the performance of your unit.
