  • What is the average life expectancy of equipment?

    Most systems last between 10-20 years. As equipment gets older, its efficiency can decrease. You may notice it gets noisier and needs repairs frequently. When a unit begins to fail, you can overhaul the system or replace it. New systems are designed with more energy-efficient equipment. We can give you a free quote on the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back with lower energy usage.

  • Can I just replace the outdoor unit with an older system to save money?

    No. Replacing just the outdoor unit will lower the efficiency of the unit. You can lose up to 15% of a unit's efficiency! What’s more, your system may fail sooner than normal. Most manufacturers' warranties will be voided. Always replace the indoor cooling coil with the outdoor unit.

  • Will a bigger-sized system perform better?

    No, you don't need your air conditioner to be too big. Air conditioners control the comfort level in your home by cooling air and removing humidity. An oversized air conditioner will cool your home faster but will use more energy in the long run and will not remove humidity adequately.


    A unit that’s too big will have short-run cycles. It may take a short time to cool the air, but the unit shuts off before enough air blows across the indoor coil where moisture condenses into water and drains from the system. This can lead to mold and mildew problems.


    Running short run cycles also means the system starts and stops more often which uses more energy, causing wear and tear. Air conditioners operate more efficiently during long-run cycles.


    It’s the same for heating systems. An oversized furnace will warm your house quicker, but it uses more fuel and causes higher temperature swings in the home.


  • Why is a system with matched components so important?

    Comfort. When all components are properly sized for a home, you can control how much heating or cooling you need. Also, a properly sized matched system allows every component to perform as designed. This means that proper cycle times are maintained, humidity is controlled, and the system’s sound is minimized.


    Another reason is efficiency. Most systems people purchase are too large for their homes, using more energy than needed. A matched system provides just the right amount of heating and cooling, so you get the most value for your utility dollar.


  • How often should I change my air filter?

    Replace the air filter in your furnace regularly. Dirty filters reduce the amount of air flowing through a system and make the furnace work harder. How often you change the filter depends on the type of filter you use. Reach out to us. We can give you proper guidance depending on the size of your equipment.

  • Why should I switch to a high-efficiency air filter?

    Proper air filtration is important to the health of your heating and cooling system and the health of your family. Without proper filtration, dust and dirt build up in your system which impacts operation and efficiency. High-efficiency filters remove more dust, dirt, pollen, mold, and other particles from the air. If you have allergies or other respiratory problems, you should consider a high-efficiency filter. No matter what type of filter you choose, change it regularly.

  • Should I have my furnace and air conditioner serviced every year?

    Yes. Proper maintenance will lower energy and repair costs, prevent breakdowns, and prolong the life of the equipment. Neglecting necessary maintenance ensures a decline in air conditioning performance while energy use increases.

  • Why should I purchase a service agreement?

    Without warranty coverage, a breakdown can mean high expenses in parts, labor, or both. With one of our service agreements, you avoid unexpected expenses. While no warranty can guard against every problem, we can explain the broad range of protection our service agreements provide.

  • How can I reduce allergens and improve the air quality in my home?

    With a high-efficiency air cleaner, you can remove up to 99% of the spores and pollen. There is also a reduction in household dust, dirt, smoke, and other air pollutants. Your indoor air will become cleaner while reducing allergens and dust that circulate throughout your house. With a whole-house humidifier, you can say goodbye to the discomfort of dry indoor air. The humidifier reduces itchy skin, scratchy throats, static electricity, and damage to your furnishings. Since humid air feels warmer than dry air, you won’t have to set the thermostat as high to get the comfort you want. A lower thermostat setting will reduce the costs of your energy bill.

  • I am concerned about mold growth, what should I do?

    Molds are part of our natural environment. Outdoor molds break down dead organic matter including fallen leaves and dead trees. Indoor mold growth should be avoided. Molds reproduce using tiny spores; spores are invisible to the eye and float through outdoor and indoor air. Mold can begin growing indoors when mold spores land on wet surfaces. There are many types of molds. None of them will grow without water or moisture. 


    When humid air passes over chilled cooling coils, water condenses and will drip through the coils into a collection pan where it continuously drains. Problems may occur when water collects and becomes stagnant if it’s blocked, either on the coils or the drip pan. The pan grows mold that can infect your home with dangerous mold spores quickly. Problems also exist when the HVAC ducting contains microscopic mold spores that stay continually present and blow contaminants around the home or office.


    You can do 3 things to prevent mold growth in your system:


    • Preventative maintenance
    • Install ultraviolet lights next to the cooling coils
    • Keep ductwork clean and use a high-efficiency filtration system
