    HVAC FAQ

    HVAC FAQ

    What does HVAC stand for?

    HVAC (pronounced h-vack or spelled out) stands for Heating, Ventilating and Air Conditioning. The three functions of heating, ventilating, and air-conditioning are closely interrelated. All seek to provide thermal comfort, acceptable indoor air quality, and reasonable installation, operation, and maintenance costs. HVAC systems can provide ventilation, reduce air infiltration, and maintain pressure relationships between spaces. Your heating and air technician goes by the name of HVAC contractor, and can provide heating repair expertise.

    What is the life expectancy of my HVAC system?

    The average life expectancy of your HVAC system depends on many factors. How often you run your system, the system’s age, its make and model, and if it was serviced regularly over the course of its life can all play a significant role in how long your system will last you. You can expect your furnace and/or air conditioner to last approximately 15 years. A heat pump can last 16+ years.

    How often should I replace the filter?

    At a minimum, it is always a good idea to change filters at the start of the heating and cooling seasons and then in between according to your need. Also, it is a good idea to have your heating and air system checked at the beginning of heating and cooling season to insure proper operation.

    How often should I have maintenance done on my air conditioner?

    You should have maintenance done on your air conditioning system at least once a year – spring to early summer being the best times. This not only ensures maximum efficiency, it enables us to foresee any likely problems that may occur in the near future.

    Why should I replace my working furnace or air conditioner?

    Although your present furnace or air conditioner may be working, if it is more than 12 years old you should consider replacing it with a new high efficiency system. A new heating and air conditioning system could save up to 50 percent on energy costs, and save you money in the long run on heating repairs. While these products save you money on your utility bills, they also offer a better degree of comfort within your home.

    How important is it to get the right size of heating and cooling equipment?

    Sizing HVAC equipment is very important from the perspectives of both comfort and energy use. Heating and cooling equipment that are over-capacity will not run as frequently (or as long when it does run). In both cases, this may mean poor humidity control. It could also result in temperature variations or noticeable cycling. Over-capacity equipment will not be as energy efficient either. On the other hand, equipment that is under-sized, will obviously result in loss of comfort during temperature extremes.

    How can I increase the efficiency and life of my home’s heating and cooling systems?

    A few quick tips:

    • Clean and replace your filters frequently.
    • Your system will heat and cool more evenly when the blower is in the “on” position. The blower provides constant air movement throughout the home, and allows for better filtration.
    • Install shades, drapes, shutters or screens on windows that are exposed to extreme sunlight to keep room temperatures at moderate levels.

    How do I find the indoor air quality of my home?

    The indoor air quality of your home can depend on a lot of factors. Pollutants from every day cooking or cleaning, pet dander, or dust can build up over time. Particulates trapped in the air can carry viruses or bacteria, and aggravate conditions like asthma and allergies. Electric Today can provide an indoor air analysis and give you personalized results based on what we find.

    What temperature should I set my thermostat?

    Obviously, the time of year becomes a crucial factor for desired temperature settings. In summer months, the average temperature setting is 76°-78°, and 69°-71° during the winter. Remember, when leaving your house; try to avoid drastic temperature changes. Do not set your temperature back more than 5°; this will cause your unit to work harder to achieve the desired temperature setting.

    What are programmable thermostats and what are their advantages?

    There are numerous programmable thermostats available on the market today that offer many new and exciting features. And because they are electronic, they are more accurate and efficient than thermostats that contain mercury. With programmable thermostats, you can control the temperature in your home at various times of the day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.
