Air filters should be checked monthly and replaced every 90 days, or more frequently if you have pets or allergies. Regular filter changes improve air quality and help your system run efficiently.

The ideal time is at least twice a year—once in the spring, before air conditioner season, and once in the fall, before heating season.

Seasonal tune-ups help spot problems early and keep your system running smoothly.

Clear debris around your outdoor AC unit, keep vents and registers uncovered, replace filters regularly, and seal any air leaks around windows and doors to prevent energy waste.

Use a programmable or smart thermostat for better temperature control, seal duct leaks, schedule regular maintenance, and consider upgrading to ENERGY STAR^®-rated equipment.

Clean ducts ensure better airflow, reduce dust and allergens, and prevent the system from working harder than necessary, which saves energy and extends equipment life.

Additionally, keeping your air ducts clean is crucial for protecting your loved ones' health because accumulated dust, mold spores, pet dander, and other irritants circulate through your home's air, potentially triggering allergies, asthma, and respiratory infections.

Regular air duct cleaning minimizes exposure to these harmful particles, helping to create a safer, healthier indoor environment where everyone can breathe easier and experience fewer respiratory issues.

Most HVAC repairs are completed the same day, though the exact time depends on how complex the issue is and the availability of certain parts.

Common repairs like thermostat replacements or minor electrical fixes often take under an hour.

More involved repairs, such as refrigerant leaks or compressor replacements, might extend over several hours or even require multiple visits if special parts need to be ordered. Our technicians strive to complete repairs promptly, restoring your comfort quickly.

We perform thorough diagnostics and testing after the work to ensure your system runs safely and efficiently. This approach helps get your heating or cooling back online with minimal disruption.

Furnaces and AC units generally last 10-15 years with proper maintenance. Timely repairs and tune-ups can extend this life span.

So, if you notice an issue or your system is operating differently than it normally does, contact our professionals immediately.

The following issues may indicate that your system needs attention:

• Uneven Heating or Cooling – If you notice some rooms feeling too hot while others remain cold, your system might be struggling to distribute air evenly. This could be a sign of failing components, duct leaks, or improper sizing.
• Unusual Noises – Grinding, rattling, banging, or squealing sounds coming from your HVAC system indicate mechanical trouble that needs prompt attention.
• Frequent Cycling – If your system turns on and off repeatedly without completing full cycles, it’s working inefficiently and may have thermostat or refrigerant problems.
• Rising Energy Bills – A sudden increase in utility bills without changes in usage often signals your HVAC system is losing efficiency and working harder than necessary.
• Poor Airflow – Weak or inconsistent airflow from vents can be caused by clogged filters, faulty blower motors, or ductwork issues, leading to discomfort and strain on your equipment.
• Foul or Strange Odors – Musty smells suggest mold or mildew in the ducts, while burning odors could indicate electrical or mechanical malfunctions requiring immediate service.

To help keep your indoor air quality at its best, you should:

• Change Air Filters Regularly – Regular air filter replacement—typically every 30 to 90 days—helps trap dust, allergens, and other pollutants before they circulate through your home.
• Use Air Purifiers – Air purifiers complement your HVAC system by capturing even smaller airborne particles like bacteria, viruses, and smoke, further reducing allergens and improving indoor air quality.
• Keep Ducts Clean – Dirt, dust, and mold can accumulate in ductwork over time, circulating pollutants when your system runs. Regular professional duct cleaning removes these contaminants, protecting your family's respiratory health and the lifespan of your HVAC system.
• Maintain Humidity Levels – Maintaining moderate indoor humidity between 30 and 50% helps prevent mold growth and reduces dust mite populations, making the air healthier to breathe.

If your AC is over 12 years old, requires frequent repairs, or fails to cool efficiently, it might be time to consider replacement.

Annual maintenance before peak cooling season helps ensure your AC runs efficiently and prevents breakdowns.

A malfunctioning air conditioning system is never fun, especially during peak summer months.

Common signs of AC problems include:

• Warm air coming from vents
• Strange or unpleasant odors
• Water leaks around the unit
• Excessive or unusual noises
• Reduced cooling efficiency
• Poor or weak airflow

If you notice any of these signs, contact our HVAC contractors in Wilmington. We’re happy to help restore comfort to your home or business.

Yes! We recommend energy-efficient systems, programmable thermostats, proper maintenance, and sealing duct leaks to reduce costs.

Programmable thermostats, in particular, can save homeowners about 10% on heating and cooling bills by automatically adjusting temperatures when you're away or asleep, leading to substantial long-term savings.

Smart thermostats take this further by learning your schedule and preferences, optimizing comfort while minimizing energy waste.

Some signs that your furnace needs repair include frequent breakdowns, strange noises, uneven heating, or rising energy bills. You may also need a furnace replacement if the cost of a repair is significantly more than the cost of a replacement.

Heat pumps benefit from annual tune-ups to maintain efficiency and prevent costly repairs.

Regular servicing keeps key components clean and functioning properly, which helps your system operate smoothly in both heating and cooling modes throughout the year.

Annual maintenance also helps identify small issues before they develop into major problems, reducing the risk of unexpected breakdowns and extending the lifespan of your heat pump.

By investing in yearly care, you can enjoy consistent comfort while keeping energy bills in check.

You can perform some basic furnace maintenance tasks yourself, including:

• Changing air filters regularly
