FAQ

Most systems have a lifetime of 10 to 20 years. As your equipment gets older, it’s efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it’s age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old.

Unfortunately, no. Replacing only the outdoor unit will lower the efficiency of the unit. In fact, you can lose up to 15% of the unit’s efficiency! Even worse, your system may fail sooner than normal and most manufacturers’ warranties will be voided. You should always replace the indoor cooling coil with the outdoor unit.

A good rule of thumb is every time you pay your power bill. Dirty air filters reduce the amount of air flowing through a system and make the furnace work harder to maintain the temperature. How often you change the filter depends on the type of filter you use, if you have pets, and the size of your equipment. Please give us a call and we can give you proper guidance.

Yes. Keeping your system properly maintained will lower energy and repair costs, prevent breakdowns and prolong the life of your equipment. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

There are several reasons an AC system may fail to turn on. One of those is frayed or disconnected wires that connect to your thermostat. Another is a thermostat that is malfunctioning and may need to be replaced. If you have either of these issues S-Tek Heating & Air is here to help.

Normal cooling settings are 75 degrees – 80 degrees. Normal heating settings are 68 degrees- 72 degrees. You should always set your thermostat to the highest possible setting that is comfortable for you in the summer, and the lowest comfortable setting in the winter. Setting your thermostat in this way will maximize your energy savings. On average, every 1 degree of temperature change is equal to about 10% energy savings. For example, changing your thermostat setting from 75 degrees to 76 degrees in the summer could result in about a 10% savings on your cooling costs.
