Top HVAC Maintenance Tips for 2025

5 HVAC Maintenance Services You Can’t Afford to Skip

With a new year comes new goals, and one resolution that Midlands, SC homeowners should prioritize is HVAC maintenance. A well-maintained heating and cooling system means:

• Fewer breakdowns and emergency repairs
• Lower energy bills
• Better indoor air quality
• A longer lifespan for your HVAC system

If you want to avoid costly repairs and stay comfortable year-round, now is the perfect time to commit to these five essential HVAC maintenance resolutions.

Service #1: Professional HVAC Tune-Up

One of the most effective ways to keep your HVAC system running efficiently is by scheduling an HVAC tune-up with a professional technician. Regular inspections help catch small issues before they turn into expensive repairs.

What happens during an HVAC tune-up?

• Checking and tightening electrical connections
• Inspecting the blower motor and fan
• Lubricating moving parts
• Cleaning the condenser and evaporator coils
• Testing thermostat accuracy

For the best results, schedule an HVAC tune-up twice a year — once before summer and again before winter. Book your HVAC maintenance appointment today to ensure your system is prepared for whatever 2025 brings.

Service #2: Replace Your Air Filters Regularly

Clogged air filters make your HVAC system work harder, reducing efficiency and increasing energy bills. Dirty filters also contribute to poor indoor air quality, which can trigger allergies and respiratory issues.

How often should you replace your air filters?

• Every 1 – 2 months for households with pets or allergies
• Every 3 months for homes without pets
• Every month during peak heating and cooling seasons

Service #3: Seal Drafts and Check Insulation

When cold air leaks in during winter or cool air escapes in summer, your HVAC system has to work harder. Sealing your home properly keeps your HVAC performance energy-efficient, plus it lowers heating and cooling costs.

Ways to improve your home’s efficiency:

• Seal cracks and gaps around doors and windows with caulk or weatherstripping
• Check attic insulation to prevent heat loss
• Close fireplace dampers when not in use
• Use ceiling fans year-round to help distribute air evenly
