Expert HVAC Services in Knollwood
HVAC systems, like all equipment, experience wear and tear during operation. The only difference between an efficient and reliable unit and a problematic one is maintenance. You must have a licensed technician inspect, lubricate, recalibrate, clean, and fix areas of weakness at least once a year. In fact, failure to schedule maintenance can void your HVAC warranty.
It’s important to understand that even with routine maintenance, malfunctions can still occur. Factors such as airflow, the amount of dust in your living space, usage habits, and the age of the system in North Chicago can impact its integrity.
Refrigerant leaks, faulty thermostats, dirty filters, blocked vents, and more can cause insufficient heating and cooling. For heat pumps and AC units, the refrigerant is the compound that allows for heat transfer from one area to another. For example, in air conditioners, refrigerant transfers heat from indoor air to the outside environment, leaving your rooms feeling cooler.
When there is less of this compound due to leaks, your unit won’t be able to transfer heat efficiently, leading to insufficient heating or cooling. Other issues, like a faulty thermostat, can prevent the system from reaching the desired temperatures. Dirty filters and blocked vents restrict airflow, making it difficult for the HVAC system to supply sufficient amounts of conditioned air.
Frequent cycling can also happen because of all the problems mentioned above. A healthy HVAC unit should cycle two to three times an hour. If your system seems fine but still cycles often, you should call an HVAC contractor to recommission it. An improperly sized HVAC unit is another common cause of short cycling.
Strange sounds, smells, and rising energy bills are indicative of already existing issues. For instance, squealing noises often suggest a problem with the belt or motor bearings, which may need lubrication or replacement. Musty odors could mean that you have mold, mildew, or bacteria growing inside or around your HVAC system. On the other hand, rising energy bills show that your unit is working harder and longer than it needs to.
Consider HVAC replacement if your equipment is older than 10 years or frequently breaks down. A new system is more efficient, effective, and convenient to use. New models also comply with the latest regulations and environmental standards.
