  • What causes the dust in our house?

    Dust is a mix of small particles from various sources inside and outside your home. Here are the main reasons for dust:


    • Shedding: Our skin cells, hair, and clothing fibers constantly flake off, adding to the dust. Pets contribute fur and dander.
    • Outdoor invaders: Soil, pollen, and dust particles from outside gets in through open windows, doors, and shoes. Living on a dirt road or near construction can worsen this.
    • Fabric traps: Rugs, carpets, furniture upholstery, and curtains trap dust particles.
    • Airborne circulation: Dust mites thrive in warm, humid environments. Their droppings and dead bodies become part of the dust.
    • Other factors: Poor ventilation, infrequent cleaning, leaky doors, and leaky windows lead to dust buildup.

  • What creates humidity in the house?

    High humidity can make your home feel stuffy, uncomfortable, and lead to mold growth. Here are some reasons why your house might be humid:

    • Weather: If you live in a humid and warm climate, there's more moisture in the air that can get into your house.
    • Daily activities: Showering, cooking, and doing the laundry bring moisture into the air. Keep the bathroom door closed and use exhaust fans in the kitchen and bathroom.
    • Venting issues: If your dryer vents into the house, it can add significant moisture. Also, a broken AC unit might not remove moisture from the air.
    • Leaks: Leaky pipes, basements, or crawlspaces can bring moisture into your home.
    • Structural problems: Poorly sealed doors, windows, or foundations can let humid outdoor air get inside your house.

  • What causes cold spots in the house?

    Feeling surprising chills in certain areas of your home can be frustrating. Here are common factors that can contribute to cold spots:


    Airflow Problems:

    • Blocked vents: Furniture, toys, or rugs, can block vents, preventing warm air from circulating.
    • Leaky ducts: Duct holes or tears can allow heated air to escape before reaching its destination.
    • Duct sizing issues: Ducts that are too small or too large for your house can lead to uneven airflow.
    • Return vents: Make sure return vents aren't blocked, as they allow air to circulate back to the heating system.
    • Insulation issues: Poor insulation in attics, crawlspaces. and walls, allowing heat to get inside and making those areas feel colder.
    • Door and window leaks: Drafty doors and windows let cold air get in, creating cold spots near them.
    • Thermostat malfunction: A faulty thermostat might not accurately display the temperature, leading to uneven heating.
    • Improperly sized furnace: If your furnace is too small for your house, it can't keep up with heating demands, especially in larger spaces.

  • Why is my thermostat not displaying the correct temperature?

    There are 2 reasons why your thermostat might not reach the correct temperature - issues with the thermostat itself, or problems with your HVAC system. 


    Thermostat Issues:

    • Needs calibration: Over the years, thermostats become less accurate. Consult your thermostat's manual for calibration instructions.
    • Dirty or dusty: Dust buildup on the sensor can cause it to display the wrong room temperature. Gently clean the thermostat with a soft cloth.
    • Low batteries: If your thermostat uses batteries, check if they're weak and replace them with new ones.
    • Incorrect settings: Double-check that the thermostat is set to the correct mode (heat or cool) and the desired temperature.
    • Placement: Keep your thermostat away from lamps, vents, or drafty areas. 
    • Malfunctioning thermostat: If none of the above solutions work, your thermostat might be faulty and need to be replaced.

    HVAC System Issues:

    • Dirty air filters: A clogged air filter hurts airflow, making it harder for your HVAC system to reach the desired temperature. Replace your air filter regularly. 
    • Blocked vents or ducts: Furniture, rugs, or closed vents can affect air circulation. Ensure vents are open and unobstructed. For issues with ducts, consult us. 
    • Undersized HVAC system: If your system is too small for your house, it might not be able to maintain the right temperature.
    • HVAC malfunction: There could be problems with the air conditioner, furnace, or parts. If you think you have an HVAC issue, call us for service.

  • How often should I change my filters?

    The recommended frequency for changing air filters depends on a few factors:


    Filter Type:

    There are 2 main types of air filters:

    • Fiberglass filters: They are the most affordable option, but they also collect less dust and allergens. They should be changed every 30 days, or more often in heavily polluted environments.
    • Pleated filters: They are more expensive upfront, but last longer and capture more dust particles. They can generally last up to 90 days, depending on usage.

    Home Environment:

    • Pets: If you have pets, they shed fur and dander, which can clog air filters more quickly. In homes with pets, consider changing filters every 45-60 days.
    • Air quality: If you live in an area with high pollution levels, dusty environments, or pollen, you'll need to change your filters more often, likely every 45-60 days.
    • Seasonality: During seasons with heavy pollen or allergens, you might need to change your filters more frequently, perhaps every 6-8 weeks.
