Signs Your AC Needs Repair Before the Heat Hits

, , , , ,

As summer approaches, the last thing you want is for your air conditioner to fail during a heatwave. Catching problems early can help you avoid unexpected breakdowns and costly emergency repairs. Here are the key signs that indicate your AC needs professional attention before the summer heat arrives.

Weak or Warm Airflow

If your AC is running but not cooling your home effectively, or if the airflow feels weak, there could be a problem with the compressor, refrigerant levels, or a clogged air filter. Addressing this early can prevent a complete system failure.

Unusual Noises

Loud banging, grinding, or squealing sounds can indicate mechanical issues such as loose components, failing motors, or a worn-out belt. Ignoring these sounds may lead to more extensive damage over time.

Frequent Cycling

Your AC should run in consistent cycles, turning on and off as needed. If it’s cycling on and off too frequently, it could be due to a faulty thermostat, refrigerant issues, or an oversized system. A professional can diagnose and resolve the problem.

Higher Energy Bills

A sudden spike in your energy bill without an increase in usage often means your AC is working harder than it should. Reduced efficiency could be caused by dirty coils, refrigerant leaks, or an aging system that needs servicing.

Strange Odors

A musty or burning smell coming from your AC vents can indicate mold growth, electrical issues, or a problem with the insulation around your wiring. Addressing these issues promptly can improve air quality and safety.

Excessive Humidity Indoors

Your AC should help regulate indoor humidity levels. If you’re experiencing high humidity inside your home, it could mean your AC is not functioning correctly or that your system needs recalibration.

Water or Refrigerant Leaks

Puddles of water around your indoor unit or visible refrigerant leaks are signs of trouble. Refrigerant leaks can affect your system’s performance and efficiency, while water leaks can lead to mold growth and water damage.

Inconsistent Temperatures

If some rooms in your home are significantly cooler or warmer than others, your AC may have issues with airflow, ductwork, or thermostat calibration. A professional inspection can pinpoint the cause.

AC Won’t Turn On

If your air conditioner isn’t turning on at all, it could be due to a tripped circuit breaker, a malfunctioning thermostat, or a more serious electrical issue. A trained technician can quickly diagnose and restore functionality.

Your AC Is Over 10 Years Old

Older AC units are more prone to breakdowns and reduced efficiency. If your system is over a decade old and frequently needs repairs, it may be time to consider an upgrade to a more energy-efficient model.

Don’t Wait Until It’s Too Late! Taking care of minor AC issues now can prevent costly repairs and ensure your system is ready to handle the summer heat. If you’ve noticed any of these warning signs, contact Marsh Heating & Air Conditioning today.

Spring HVAC Checklist: Get Your System Ready for Warmer Weather

, , , , , , ,

As the days grow longer and temperatures begin to rise, now is the perfect time to prepare your HVAC system for the warmer months ahead. A well-maintained system ensures energy efficiency, prevents costly breakdowns, and keeps your home comfortable as spring transitions into summer. Follow this comprehensive spring HVAC checklist to keep your system running smoothly.

Replace or Clean Air Filters
Your HVAC system’s air filters collect dust, pollen, and other airborne particles. A dirty filter reduces airflow, making your system work harder and decreasing efficiency. Replace disposable filters or clean reusable ones every 1-3 months to maintain optimal performance and indoor air quality.


Inspect and Clean Air Ducts
Over time, dust, allergens, and even mold can accumulate in your ductwork, impacting your home’s air quality. Schedule a professional duct cleaning if you notice excessive dust buildup or experience allergy symptoms inside your home.


Check the Thermostat
Test your thermostat to ensure it’s working correctly. If you haven’t already, consider upgrading to a programmable or smart thermostat, which can help reduce energy consumption and enhance comfort by automatically adjusting temperatures based on your schedule.


Clear Debris Around the Outdoor Unit
Your HVAC system’s outdoor unit can accumulate leaves, dirt, and debris over the winter months. Clear away any obstructions to allow for proper airflow. Trim any vegetation at least two feet around the unit to prevent blockages and ensure efficient operation.


Inspect the Condensate Drain Line
The condensate drain removes excess moisture from your air conditioning system. A clogged drain can lead to water damage and mold growth. Check for blockages and flush the line with a mixture of vinegar and water to keep it clear.


Test the Air Conditioning System
Before the first hot day of the year, turn on your air conditioner to ensure it’s functioning properly. Listen for any unusual noises, check for weak airflow, and monitor how quickly your home cools down. If you notice any issues, schedule a professional inspection.


Schedule Professional HVAC Maintenance
Annual HVAC tune-ups can improve efficiency, extend the lifespan of your system, and catch minor issues before they become major problems. A professional technician will inspect the entire system, check refrigerant levels, lubricate moving parts, and ensure everything is operating as it should.


Seal Air Leaks and Improve Insulation
Check windows, doors, and ductwork for air leaks that could let cool air escape, causing your system to work harder. Sealing leaks and adding insulation can improve energy efficiency and lower utility bills.


Evaluate Your System’s Age and Efficiency
If your HVAC system is more than 10-15 years old, it may be time to consider a replacement. Newer systems are more energy-efficient and can significantly lower your heating and cooling costs. A professional can assess your system’s condition and recommend whether a repair or replacement is the best option.


Upgrade to Energy-Efficient Equipment
If you’re looking to reduce energy consumption and increase home comfort, upgrading to an ENERGY STAR-certified HVAC system can be a smart investment. Modern units use advanced technology to optimize performance while saving on utility costs.
