A Maintenance Check is a scheduled, inspection and maintenance of your HVAC system in preparation of the upcoming season. These checks are usually performed semi-annually to maintain peak efficiency, help prevent utility overpayment, and avert system failures—all of which can help extend the life of your HVAC system.
Most people don’t think about regular maintenance when it comes to their heating and air unit. Ordinarily the only time the unit gets attention is when it’s not working. Following are a few reasons why you should do a regular service of your unit:
Many people do not realize that your heating and air conditioning system is one of the biggest uses of energy in your home. Neglected maintenance will result in higher utility bills and decrease the life of your unit. The old cliché’ “out of sight, out of mind” is true. Your HVAC unit is one of those things you don’t think about until it fails. Decreased efficiency, utility overpayment, discomfort, loss of productivity, premature replacement, and higher repair cost are all results of neglect.

A programmable thermostat is ideal for people who are away from home during set periods of time throughout the week. Through proper use of pre-programmed settings, a programmable thermostat can save you about $180 every year in energy costs.
If the temperatures that your thermostat reads are not reflective of the average temperature in your home, your air conditioner will either operate too often or not often enough. In either case, it will be difficult to maintain the temperature levels that you want in your home. Since thermostats are typically installed when your air conditioner is installed, improper placement might occur due to a poor system installation or a remodel to your home that changes the area surrounding your thermostat.
In direct sunlight. If the sun is shining through a window directly on your thermostat, your thermostat will think your home is hotter than it actually is. This will cause your air conditioner to operate more often than it needs to, which will make your home too cool and cause your system to consume more energy.
Near air vents. If your thermostat is near an air vent, cool air from your air conditioner can blow on it and your thermostat will think it’s cooler than it really is. This can cause your air conditioner to short-cycle, which is bad for your system and your home comfort.
Near other drafts. In addition to your air vents, drafts can come from windows, doors, fans and other places that can influence your thermostat’s temperature readings.
Near heat-producing appliances. If your thermostat is near any heat-producing appliances (especially near your kitchen), your thermostat will get warmer readings than the rest of your home and tell your air conditioner to stay on longer.
In a de-centralized location. Your thermostat should be placed in the center of your home, because that’s where you’re most likely to get an average reading of your home’s temperature levels. If it’s not in a central location, its temperature readings will likely not reflect the rest of your house and your home will either be too hot or too cold.
Like central air conditioners, these units have a split design but without an elaborate system of ducts. The split system (also called a mini-split, ductless split, or duct-free system) has at least one unit inside the home (this is the evaporator) and one outdoor unit (the condenser). Small tubes of refrigerant run from the outdoor unit to the indoor units—these are also known as line sets. Indoor units can be wall or ceiling mounted. Ductless splits can be used to cool one zone or multiple zones, applying two to four indoor units to one condenser. The indoor units can all be used independently of each other.
