How to Keep Your Heating and Cooling Unit in Good Shape

Your heating and cooling system is a critical component of your home’s comfort and efficiency. Whether you’re trying to stay cool during summer or warm in the winter, your HVAC system plays a central role in creating a cozy and healthy environment. At Trust Heating and Air, we know that keeping your system in good shape not only saves money but also extends its lifespan and improves indoor air quality. Here’s a comprehensive guide to maintaining your heating and cooling unit.

1. Regular Maintenance is Key

Scheduling regular maintenance for your HVAC system is one of the best ways to ensure it remains in optimal condition. Routine check-ups can catch small problems before they turn into costly repairs.

What Regular Maintenance Includes

Seasonal Tune-Ups: Schedule professional maintenance twice a year—once in spring for cooling and once in fall for heating.
Inspection of Components: Technicians will inspect the blower motor, electrical connections, thermostat, and other critical components.
Lubrication: Moving parts are lubricated to reduce friction and prevent wear and tear.
Refrigerant Levels: For cooling systems, refrigerant levels are checked and adjusted if necessary.

Benefits of Maintenance

Prevents breakdowns.
Improves energy efficiency.
Extends system lifespan.
Maintains warranty coverage (many manufacturers require annual servicing).

2. Change the Filters Regularly

Air filters trap dust, debris, and allergens, keeping your air clean and your system efficient. Dirty filters can restrict airflow, strain your HVAC unit, and lead to higher energy bills.

How Often to Replace Filters

Every 1-3 Months: For standard 1-inch filters.
Monthly: If you have pets, allergies, or live in a dusty area.
Longer Intervals: For high-efficiency filters or if recommended by the manufacturer.

Signs Your Filter Needs Replacing

Reduced airflow from vents.
Dust buildup near vents or on surfaces.
Increased energy bills.

3. Keep Your Outdoor Unit Clean

When your outdoor condenser or heat pump is exposed to the elements, it is susceptible to dirt, leaves, and debris. Keeping it clean ensures optimal airflow and heat exchange.

Steps to Clean Your Outdoor Unit

Turn Off Power: Always turn off the system at the breaker before cleaning.
Remove Debris: Clear leaves, twigs, and grass from around the unit.
Clean the Coils: Use a garden hose to gently rinse the coils. Avoid using high pressure, which then can damage them.
Trim Vegetation: Maintain at least 2 feet of clearance around the unit.

4. Optimize Your Thermostat Settings

Your thermostat controls the temperature and energy use of your HVAC system. If you use it effectively, then you can enhance comfort and save money.

Best Practices for Thermostat Use

Set Seasonal Temperatures: Use energy-efficient settings, like 78°F in summer and 68°F in winter.
Upgrade to a Programmable or Smart Thermostat: These devices automatically adjust temperatures based on your schedule and can be controlled remotely.
Avoid Extreme Changes: Drastic temperature swings can strain your system.

5. Seal and Insulate Your Ductwork

If ducts are leaky or poorly insulated, then they can cause significant energy loss and uneven heating or cooling. Properly sealed ducts ensure that conditioned air reaches its destination efficiently.

Signs of Leaky Ductwork

Uneven temperatures between rooms.
Higher-than-usual energy bills.
Dust buildup around vents.

Steps to Address Ductwork Issues

Seal Leaks: Use HVAC tape or mastic sealant to close gaps.
Add Insulation: Insulate ducts in unconditioned spaces like attics and basements.
Professional Testing: Have a professional perform a duct leakage test to identify and fix hidden issues.

6. Monitor Your Energy Bills

A sudden spike in your energy bills is usually because there is a problem with your HVAC system. Monitoring your bills helps you catch issues early and ensure your system is running efficiently.

Common Causes of Increased Energy Bills

Dirty filters or coils.
Refrigerant leaks.
Malfunctioning components.
Poor insulation or ductwork issues.

7. Be Mindful of Unusual Noises or Smells

Your HVAC system will occasionally make some noise, but unusual sounds or smells often signal a problem that needs immediate attention.

Common Noises and Their Causes

Banging or Clanging: Loose parts or components.
Hissing: Refrigerant leaks.
Squealing: Worn belts or motor issues.

Unusual Smells

Burning Odor: Could indicate electrical issues.
Musty Smell: Sign of mold or mildew in the ducts or unit.
Gas Smell: Possible gas leak—turn off the system and call a professional immediately.

8. Avoid DIY Repairs

While regular cleaning and filter replacement can be done by homeowners, most HVAC repairs should be left to professionals. Attempting DIY repairs can void your warranty, cause further damage, or even lead to safety hazards.

9. Schedule Professional Inspections After Extreme Weather

Extreme weather conditions, such as storms, heatwaves, or freezes, can stress your HVAC system. Scheduling a professional inspection is smart because it ensures your unit is functioning properly and hasn’t sustained damage.

10. Replace an Aging System When Necessary

Even with the best maintenance, HVAC systems eventually wear out. Most units last 10-15 years, depending on the type and maintenance history. Replacing an old, inefficient system can save you money and provide better comfort.

Signs It’s Time to Replace Your HVAC System

Frequent and costly repairs.
Uneven heating or cooling.
Rising energy bills despite regular maintenance.
The system is over 15 years old.
