Question:

What is the average life expectancy of a system?

Answer:
Most Air Conditioning & Heating systems have a lifetime of 10 to 20 years. As your Air Conditioning or Heating equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show its age, you have two choices — You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new Air Conditioning or Heating system designed with newer, more energy-efficient equipment makes sense, especially if your HVAC system is 7 or more years old. Our certified technicians can provide a FREE in-home estimate of the cost of a new system as well as a payback schedule that will show you how much a newer, more efficient system will pay you back in lower utility bills.
Question:

How can I reduce my energy costs?

Answer:
Here are some ideas to reduce your energy costs: upgrade to a high-efficiency Air Conditioning or Heating system, install ceiling fans, have annual maintenance performed, don’t block vents in well-used rooms, close vents in less-used rooms and install a programmable thermostat.
Question:

What regular maintenance do heating and air conditioning systems need?

Answer:
The most important part of HVAC maintenance aspect is maintaining unrestricted air flows. Dust, dirt, and debris are an HVAC system’s worst enemies. Whether it’s an indoor or outdoor unit, you must keep all filters clean and heat exchangers and coils free of restrictions.
Stacks recommends that your Air Conditioning & Heating system be checked and serviced twice a year; ideally a spring and autumn tune-up. Also we recommend that you change your filter regularly, depending on the type of filter you have. This alone can eliminate many of the most common problems that need fixing and can significantly reduce the likelihood of a serious breakdown. A Stacks Service Plan is your assurance that these maintenance needs are met regularly and that any potential problems are promptly identified.
Question:

Why do I need to change my filter regularly?

Answer:
Regular filter replacement helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to change filters regularly to ensure proper air flow and to keep your home free from dust, allergens and germs. Depending on the type of filter you have, you may require weekly or monthly filter replacements. Your Stacks Service Plan or installation technician will recommend the ideal filters and replacement schedules for your unit(s).
Question:

How do I assure optimal performance?

Answer:
Most maintenance should be performed only by a qualified service technician. But here are some things that you can do to assure optimal performance:<0l>

  • Keep ground mounted outdoor units clear of debris, clutter and weeds; they can reduce the air flow to the unit.
  • Use caution with weed trimmers around the unit to prevent damaging control wiring.
  • Keep pets away from the unit; pet urine can cause expensive damage.
  • Question:

    How long should my air conditioning system run in a cycle?

    Answer:
    There is no exact answer for how long your system should run during each cycle. The average air conditioner is sized to remove the heat from your home as fast as it comes in. Therefore, ideally, on a 100° day the system should be able to keep up with the incoming heat, but not gain on it and not be able to turn off. The cooler it is below 100°, the more the system will cycle on and off. So it depends on the environment of each individual home and the condition of the equipment.
    Question:

    Is there anything I should check prior to calling for service?

    Answer:
    Check to be sure that the air conditioner or furnace is turned on. Check that the breakers and the disconnects are turned on and be sure the thermostat is set correctly. Also make a note of any strange noises or smells.
    Question:

    What are the advantages of a programmable thermostat?

    Answer:
    Because they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. Plus, they allow you to automatically control the temperature in your home at different times of day without ever touching your thermostat.
    Question:

    What is two-stage heating?

    Answer:
    Two-stage heating means a furnace has two levels of heat output: high for cold winter days and low for milder days. Two-stage furnaces start in the first stage, instead of reaching full capacity all at once. That means there is no sudden blast of air. The low setting meets household heating demands 80% of the time, allowing a two-stage unit to run for longer periods and provide more even distribution of heated air. Because the furnace operates mostly in its lower-capacity first stage, it burns less fuel than a furnace that always runs at full capacity and then has to shut off when the heating demand has been met.
