Spring HVAC checklist: what to include before cooling season
- Air filter replacement : Replace or thoroughly clean your furnace and AC filters. A clean filter is crucial for maintaining steady airflow, which is essential for system efficiency and for keeping indoor air quality high by trapping dust, pollen, and other allergens. Aim to check monthly and replace every 1-3 months.
- Outdoor unit cleaning : Inspect your outdoor condenser unit and remove any accumulated leaves, twigs, grass clippings, or other debris from around its base and fins. Clear away any plants or shrubs that are too close, ensuring at least two feet of clearance on all sides for optimal airflow and heat dissipation.
- Thermostat check and calibration : Confirm your thermostat is accurately reading and controlling the temperature. Test its functionality by switching between heating and cooling modes. If you have a programmable or smart thermostat, ensure its settings are updated for the spring and summer schedule to maximize energy savings.
How to prep your air conditioner for summer
- Coil cleaning : The outdoor condenser coils can accumulate dirt and grime over time, hindering their ability to release heat. Gently spray the coils with a hose to remove surface dirt. For more stubborn buildup, a specialized coil cleaner may be necessary, but always consult your owner’s manual or a professional for guidance.
- Refrigerant level check : While this is typically a task for professionals, understanding its importance is key. Correct refrigerant levels are vital for your system to cool properly. Low levels often indicate a leak, which can severely reduce cooling capacity and strain the compressor. If you notice reduced cooling, it’s time to call a pro.
- Thermostat testing : Beyond just checking the temperature, test your thermostat’s various settings, including fan modes (auto/on) and programmable schedules. Ensure it responds promptly to changes and maintains the set temperature consistently. Consider upgrading to a smart thermostat for enhanced control and energy management.
Recommended professional services for spring
- Comprehensive system inspection : A certified technician will perform a thorough inspection of all components, including electrical connections, moving parts, and safety controls. They can find hidden issues, such as refrigerant leaks or worn-out capacitors, that DIY checks often overlook, preventing future breakdowns.
- Duct cleaning (as needed) : While not an annual task, professional duct cleaning can significantly improve air quality and system performance, typically recommended every 3–5 years. It removes accumulated dust, pet dander, mold spores, and other contaminants from your ductwork, ensuring cleaner air circulation.
- System tune-up : A professional tune-up involves precise adjustments, lubrication of moving parts, cleaning of evaporator and condenser coils (more thoroughly than a homeowner can), and checking refrigerant pressure. This ensures all components are operating as intended, maximizing efficiency and extending the system’s lifespan.
Summer care: tips to maximize cooling efficiency
- Regular filter changes : During heavy use in summer, your AC filter can get dirty quickly. Replace or clean your air filter every 1–3 months, or even more frequently if you have pets, allergies, or live in a dusty environment. A clean filter is the easiest way to ensure optimal airflow and prevent strain on your system.
- Watch refrigerant levels : While you can’t check these yourself, be vigilant for signs of low refrigerant, such as reduced cooling capacity, ice buildup on the outdoor unit, or a hissing sound. Low refrigerant not only reduces cooling but also forces your system to work harder, leading to higher energy bills and potential compressor damage.
- Keep outdoor units clear : Regularly inspect the area around your outdoor condenser unit. Remove any new growth of plants, weeds, or grass, as well as any accumulated leaves, dirt, or clutter. Maintaining at least two feet of clear space around the unit allows for proper airflow, which is critical for the condenser to efficiently dissipate heat.
DIY summer tasks homeowners can handle
- Changing filters : This is perhaps the most important and easiest DIY task. Locate your air filter (usually in the furnace or a return air vent), note its size, and replace it with a new, clean filter. This simple action keeps air moving freely and prevents dust buildup in your system.
- Cleaning the outdoor unit : With the power to the unit turned off at the breaker, use a garden hose to gently spray down the condenser coils from the outside in. This helps remove surface dirt, dust, and pollen, allowing the unit to shed heat more effectively. Ensure the area around the unit remains free of obstructions.
- Checking thermostat settings : Review your thermostat settings to ensure they are optimized for summer. Use programmable features to raise the temperature when you’re away from home and lower it when you return. Make sure the fan is set to “Auto” rather than “On” to save energy, as “On” runs the fan continuously.
When to book professional AC service in summer
- Best time to schedule : Ideally, schedule your professional AC tune-up in early spring before the summer rush. If you missed spring, late fall is also a good time for a comprehensive check-up, as it avoids the busiest seasons for technicians and ensures your system is ready for the next cooling cycle.
- Signs you need a pro : Be alert for warning signs such as strange noises (grinding, squealing, banging), weak airflow from vents, warm air blowing when the AC is on, unusual odors, or a sudden spike in energy bills. These indicators often point to underlying issues that require professional diagnosis and repair.
- Why regular service pays off : Routine professional care is an investment that pays dividends. It not only extends the equipment life of your expensive AC unit but also ensures it operates at maximum efficiency, saving you money on energy bills and preventing the discomfort and expense of emergency breakdowns during the hottest days.
Fall furnace tune-up: get ready for heating season
- Furnace inspection : Visually inspect your furnace unit for any obvious signs of wear, rust, leaks, or loose parts. Check the area around the furnace for any obstructions or combustible materials. Ensure the exhaust vent is clear and unobstructed, as blockages can lead to dangerous carbon monoxide buildup.
- Filter replacement : Just like with your AC, a fresh furnace filter is critical for efficient operation and healthy indoor air. Replace your air filter with a new one to maintain optimal airflow, prevent dust from circulating, and protect your furnace’s internal components from dirt and debris.
- Safety checks : Confirm that all safety switches and controls are working properly. This includes testing your carbon monoxide detectors and smoke alarms, ensuring they have fresh batteries. Also, check the pilot light (if applicable) for a strong, blue flame, which indicates proper combustion.
Why a professional furnace inspection before winter matters
