Heating & Cooling F.A.Q.

Frequently Asked Questions

HVAC maintenance should be scheduled at least twice a year, ideally in the spring for your air conditioner and fall for your heating system. Regular maintenance ensures optimal performance, energy efficiency, and longevity for your system.

Why Biannual Maintenance is Important

  1. Prepares for Seasonal Changes – A spring tune-up ensures your A/C is ready for summer, while a fall check-up gets your furnace or heat pump ready for winter.

  2. Improves Energy Efficiency – A well-maintained system runs more efficiently, reducing energy consumption and lowering utility bills.

  3. Prevents Costly Repairs – Technicians can catch small issues before they turn into major (and expensive) problems.

  4. Extends System Lifespan – Regular servicing helps your HVAC system last longer, delaying the need for a costly replacement.

  5. Maintains Air Quality – Cleaning and replacing filters, checking ductwork, and ensuring proper airflow improve indoor air quality.

  6. Preserves Warranty Coverage – Many manufacturers require regular professional maintenance to keep warranties valid.

Additional Maintenance Tips

  • Check and replace air filters every 1-3 months.

  • Keep vents and outdoor units free from obstructions.

  • Listen for unusual noises or performance issues and schedule service promptly.

By keeping up with routine maintenance, you can avoid breakdowns, improve efficiency, and enjoy year-round comfort.

The ideal thermostat setting for energy savings depends on the season and your comfort preferences. The U.S. Department of Energy recommends the following settings:

Summer Settings:

  • 78°F (26°C) when you’re home for a balance of comfort and efficiency.

  • 85°F (29°C) or higher when away to save energy without overworking the system.

  • Use a programmable or smart thermostat to automatically adjust settings based on your schedule.

Winter Settings:

  • 68°F (20°C) when you’re home to stay warm while keeping energy costs lower.

  • Set it back to 60-65°F (16-18°C) when away or sleeping to reduce heating costs.

Additional Energy-Saving Tips:

  • Use ceiling fans in the summer to help circulate cool air, allowing you to set the thermostat higher.

  • Wear warmer clothing and use blankets in the winter to stay comfortable at lower temperatures.

  • Seal drafts and insulate your home to prevent heat loss in winter and keep cool air inside in summer.

  • Upgrade to a smart thermostat to automate temperature adjustments for maximum efficiency.

By following these guidelines, you can save up to 10% per year on heating and cooling costs while maintaining comfort.

Strange noises from your HVAC system can indicate various issues, ranging from minor concerns to serious mechanical problems. Here are some common sounds and their possible causes:

1. Banging or Clanking

  • Likely caused by a loose or broken part inside the blower or compressor.

  • Could indicate an unbalanced blower fan or a failing motor mount.

2. Hissing

  • Often a sign of a refrigerant leak, which reduces cooling efficiency and can damage the system.

  • May also be due to a leaky air duct, causing airflow loss.

3. Screeching or Squealing

  • Usually caused by a worn-out or loose belt in the blower motor.

  • Could also mean there’s an issue with the motor bearings.

4. Rattling

  • Might be due to loose screws, debris inside the unit, or a failing motor.

  • If coming from the outdoor unit, check for leaves or twigs caught in the fan.

5. Clicking

  • Some clicking is normal when the system starts or shuts down, but frequent clicking could indicate a faulty relay or failing capacitor.

6. Buzzing

  • Could be due to electrical issues, loose wiring, or a failing compressor.

If you hear persistent or unusual noises, it’s best to schedule an inspection with an HVAC technician to prevent further damage and costly repairs.

The right HVAC system size for your home depends on several factors, including square footage, insulation, climate, and home layout. Choosing the correct size is crucial for efficiency, comfort, and longevity.

General Sizing Guidelines

HVAC systems are measured in BTUs (British Thermal Units) for heating and cooling capacity. A common rule of thumb is:

  • 1 ton of cooling (12,000 BTUs) per 400-600 square feet of living space.

  • Example: A 2,000 sq. ft. home may require a 3.5 to 5-ton A/C unit, depending on insulation and climate.

Factors That Affect Sizing

  1. Climate Zone – Homes in hotter climates need higher cooling capacity, while colder areas require more heating power.

  2. Insulation & Windows – Well-insulated homes with energy-efficient windows require less heating and cooling.

  3. Ceiling Height – Taller ceilings increase the volume of air that needs conditioning.

  4. Number of Occupants – More people generate more heat, affecting cooling needs.

  5. Ductwork & Airflow – Properly sized and sealed ducts ensure efficient air distribution.

Why Proper Sizing Matters

  • An oversized unit cools or heats too quickly, leading to short cycling, higher energy bills, and uneven temperatures.

  • An undersized unit struggles to maintain comfort, running constantly and increasing wear and tear.

For an accurate system size, have an HVAC professional perform a Manual J Load Calculation, which evaluates all key factors for optimal sizing.

Tips From The Chelsea, Michigan HVAC Experts

The highly skilled and trained technicians at Aspen One Hour are experts in all things HVAC. We’re dedicated to providing you with valuable insights and practical advice to keep your home’s heating and cooling systems running smoothly and efficiently.

An air conditioner can freeze up due to restricted airflow, low refrigerant levels, or mechanical issues. To prevent this, follow these steps:

  1. Change Air Filters Regularly – A dirty or clogged air filter restricts airflow, which can cause the evaporator coil to freeze. Replace your filter every 1-3 months, depending on usage.

  2. Keep Vents Open and Unobstructed – Ensure all supply and return vents are open and free from blockages like furniture or curtains. This allows proper air circulation.

  3. Schedule Routine Maintenance – Have your HVAC system inspected by a professional at least once a year. They can check refrigerant levels, clean coils, and ensure components are working correctly.

  4. Check for Refrigerant Leaks – Low refrigerant can cause pressure imbalances, leading to freezing. If you notice ice buildup or reduced cooling efficiency, call a technician to inspect and refill refrigerant if needed.

  5. Ensure Proper Thermostat Settings – Running your A/C at very low temperatures for extended periods can cause the system to overwork and freeze up. Keep your thermostat set at a moderate temperature.

  6. Inspect the Blower Fan – If the fan isn’t running at full speed, airflow can be restricted, leading to ice formation. A technician can diagnose and repair blower issues.

By following these steps, you can keep your A/C unit running efficiently and prevent freeze-ups.

A ductless mini-split system offers several benefits, making it an excellent choice for both residential and commercial spaces.

  1. Energy Efficiency – Mini-splits are highly efficient because they don’t lose energy through ductwork, which can account for up to 30% of energy loss in traditional HVAC systems. Many models have high SEER (Seasonal Energy Efficiency Ratio) ratings, reducing energy costs.

  2. Zoned Heating and Cooling – Unlike central air systems, which cool or heat an entire home, mini-splits allow you to control temperatures in individual rooms or zones. This customization improves comfort and energy savings.

  3. Easy Installation – Without ductwork, installation is much simpler and less invasive. The indoor unit connects to the outdoor compressor through a small hole in the wall, making it ideal for older homes, home additions, or rooms without existing ductwork.

  4. Improved Air Quality – Traditional ducted systems can accumulate dust, allergens, and mold. Mini-splits use multi-stage filtration to improve indoor air quality without the need for extensive duct cleaning.

  5. Quiet Operation – Mini-split systems run much quieter than traditional HVAC systems, making them ideal for bedrooms, offices, and other quiet spaces.

  6. Year-Round Comfort – Many ductless systems provide both heating and cooling, ensuring comfort in all seasons.

With their efficiency, flexibility, and improved air quality, mini-splits are a smart investment for any space.
