Many homeowners have limited information about their HVAC system. However, being unfamiliar with HVAC systems can cause a number of problems including unneeded service calls, an inefficient system and premature system failure. By learning about the basics of HVAC systems, homeowners can save both time and money.
Thermostat
Many HVAC service calls are a result of an improperly set thermostat. Whenever a system problem is present, it is important for a homeowner to carefully check the thermostat. Many service calls, and service fees, can be avoided by simply checking the thermostat’s settings. If the thermostat is set properly and still not working, there are a couple simple things that homeowners can do to try and correct a faulty thermostat. With an older thermostat, a homeowner can remove the outer housing and brush or vacuum away any apparent dust. With a newer programmable thermostat, new batteries should be placed into the unit. Some thermostat’s use on certain types of batteries, so it is important to make certain the properly type of battery is being used.
Maintain the Filter
The simplest way to keep an HVAC system working properly is to change the filter according to the manufacturer’s recommendation. A clean filter will reduce the amount of dust that enters the system, reducing the amount of wear on the system. A clean filter also provides adequate air to the system so that it works as efficiently as possible. In most cases, manufacturers recommend a monthly filter change.
Annual Check
HVAC systems should be inspected at least annually. While most systems will provide years of trouble free service, issues can arise. For example, ductwork can become loose and begin to leak. Leaking ducts will not cause any harm to the system, but the leaks will prevent the system from working efficiently. Problems such as leaking ducts can be found and corrected during an annual inspection.
Professional Repairs Only
The combination of high voltage electricity, high pressure components and poisonous gas make HVAC repairs the job of a trained professional. While a homeowner can replace filters and vacuum dust and debris away from the external system, internal repairs need to be made by a trained professional who can safely and properly maintain the system.
Odd Sounds Equal Problems
HVAC systems may begin to make odd sounds over time. While these sounds may not seem like a big deal, they may indicate a serious problem. A tapping noise may indicate that something is obstructing the blower. A rattle may indicate that a section of duct work has pulled apart. Whenever an HVAC system starts making a new sound, a homeowner should call a service professional to have the system inspected.
