AC repair and maintenance technicians should advise you on the need to have your unit inspected and serviced on a regular basis. At the very least, you will be guaranteed of breathing in clean air. Clogged ducts and filters can be a source of endless coughs and endless trips to the ER, especially for people with asthmatic conditions.
If you have been experiencing high energy bills, it could be an indicator you need to get your AC unit checked. Avoid waiting till the system is about to break down so you can call in a technician.
A well maintained and serviced unit consumes less energy; thus you get to save a lot of energy bills. It needs no mentioning when your unit starts to make that squeaky sound, it means its working overtime just to maintain the right temperatures hence durability is significantly compromised. This may have a huge toll on the HVAC parts and will only be a matter of time before the parts break down.
It is highly recommended that HVAC maintenance be done by a technician that has the necessary tools, knowledge, and experience. A well-trained technician will not only identify but will also fix possible air conditioning system problems that are about to happen. Some of the critical areas that a typical HVAC maintenance should cover include the following.
Your technician should be in a position to use a leak detector to check whether or not the refrigerant is leaking and to ensure the amount available is sufficient for optimal performance. In the event there are any leaks in the system, your AC technician should capture all amounts that need evacuation rather than releasing them to the environment. Regular AC maintenance also entails checking for and sealing duct leakage in the central AC systems.
The flow of air via the evaporator coil should also be checked and measured accordingly to ensure the right amount of air is going through the coil. Further, the electrical terminals ought to be checked, cleaned and tightened and a non-conductive coating applied should there be a need for a fresh coat. Your service provider should also ensure they check for thermostat accuracy and at the same time ensure the oil motors and belts are fastened accordingly. Last but not least, your technician should verify that the right electric control sequence is taking place to ensure both the heating and cooling systems are not operating simultaneously. A good technician will not only do regular maintenance on the obvious fins, coils, and filters; they should also be in a position to work on the conditions mentioned above.
