Buying a new system questions

  • Why should I replace my old heating or air conditioning system?

    A good rule in determining if your home or office is ready for and upgrade is if you air conditioning or heating system is old, inefficient or broken. New HVAC systems are as much as 30%-60% more efficient than those systems manufactured in the last decade. Furthermore, wear and tear on a system and poor maintenance can further reduce efficiency of the system. If you have a problem with unusually high electric bills or have a broken AC, considering replacing your system might be a good option. Oftentimes customers much rather upgrade rather than enduring another costly HOT summer season or constant malfunctions on an old AC. Just on the utility cost savings alone a new HVAC system may provide a nice return on your investment. PLUS, if you plan on financing the purchase, the monthly savings on your CPS (electric) bill should be taken into consideration when determining the cost of replacing a system per month. When you look at the savings an HVAC upgrade might look like a good idea.

  • How much does it cost to replace my old AC?

    The size of your home, the type and condition of the ductwork installed are the biggest factors in determining cost. At MFM we offer a complete range of systems and accessories available to meet all your needs, including your financial ones! We will help you find the right system to meet your budget and keep you comfortable.

  • What happens when I replace my old AC?

    MFM HVAC professionals install a new system adequate sized and capable of efficiently cooling your home or office. MFM will inspect several items and determine whether they need to be supplied or replaced. Some of the items include: ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil.

  • What is involved in the new system installation?

    A new HVAC system is sized and designed to efficiently cool and dehumidify. Once the system is installed, the most significant part of the new install is ductwork as it deals with airflow. The ductwork can be made of either metal or fiberglass. Sizing of the ductwork is important to deliver the right amount of air to each room. A central air conditioning system uses supply and return ducts. The supply duct is attached to the outlet of the furnace or air handler and delivers air to individual zones in your home. By calculating the amount of air that needs to be delivered to the space MFM HVAC professionals can correctly size of the ductwork going into a space.

Maintenance Questions

  • How often should I have my AC Tuned Up?

    Maintenance to your HVAC system should be performed seasonally (Spring and Fall) right before peak usage. Having your AC tuned up will not only ensure efficiency, saves you money on your CPS (electric) bill. Consistent bi-annual maintenance also enables HVAC pros to
identify possible problems that may occur in the near future. Our
MFM maintenance plans are designed to keep
your air conditioning system running at its peak efficiency year-round.

  • How do I clean the coils in my AC

    There are two “coil” systems/parts to an HVAC system. For the outside coil you don’t necessarily need to call a professional, save yourself some money and do it yourself.

    Process:

    • The job is light duty so please do NOT use a power washer (likelihood of damage is very high)
    • Before you clean the outside coil, turn off the power. The switch should be next to the outdoor unit. Use a hose and moderate water pressure to wash off dirt and debris from the unit.
    • NOTE: Cleaning the inside coil (inside the air-handler) should be handled by a professional, too many things could go wrong. That’s our opinion anyway!
  • What do I do if my system NOT heating?

    First thing you can do is check to make sure the power supply is on. If your system is electric check for blow fuses. If you system is gas powered check if the gas is on.

    If you cannot find any problems with power or energy supplies, make sure the system is set correctly at the thermostat (on position and set high enough to kick the system on). Again if you system is gas powered, check the pilot light because if it is not lit, it needs to be re-ignited (you MUST follow the instructions in the owners manual for your system).

  • What can I do to make my AC run well and save me energy?

    The most important thing you can do is clean and replace your filters
frequently. Also, a system heats and cools more evenly when the blower
is in the “on” position. The blower provides constant air movement
throughout the home, and allows for better filtration. Finally, shades, drapes, shutters, or screens should be installed on windows that are
exposed to strong sunlight throughout the day.

  • Does a digital thermostat actually save me money?

    Most thermostats are simple, it is either up or down functionality. So depending on the comfort preference people move the dial up or down. Unfortunately this method of heating and cooling wastes energy (your money). The next generation of thermostats are digital, with touch-screen controls that are easy to read and offer more features like the ability to pre-set temperatures for every day of the week to match your schedule. Benefits include functionality to save energy when you are not home even control via your mobile web enables device.

Air Quality

  • What can I do about air pollution in my home?

    The latest advances in air quality combine ultraviolet-light technology and high-efficiency air filters to combat air pollution in the home or office environment. Should you suffer from allergies or asthma investing in a heating and cooling system that reduces indoor air pollution and improves air quality might be a good solution. Ever day dust, pollen, cleaning chemicals and pet dander can make indoor air detrimental to your home or office environment. At MFM we can help you learn about HVAC systems that offer high-efficiency air cleaning with HEPA filters.

  • How often should I replace my filters?

    For optimum efficiency and filtration, we recommend that you replace
your disposable filters at least once a month. If you have washable
filters, they should be cleaned once a month.
