MARLBOROUGH, N.H. (MyKeeneNow) By this point in the summer, many homeowners start noticing something frustrating.

The air conditioning is running constantly.
The house still feels warm or humid.
And the electric bill suddenly jumps.

Most people assume that is just part of summer.
But often, it is a sign that your air conditioning system is working much harder than it should.

At Keating Plumbing & Heating, we see this every year throughout the Monadnock Region.

Why Cooling Costs Start Climbing

Even if your AC system still turns on and cools the house, small issues can quietly reduce efficiency over time.

Some of the most common causes include:

  • Dirty air filters restricting airflow
    • Outdoor units clogged with debris or pollen
    • Low refrigerant levels
    • Aging systems losing efficiency
    • Poor airflow throughout the home
    • Thermostats working harder during humid weather
    • Systems that are simply undersized for the home

The result is a system that runs longer, works harder, and uses more electricity to deliver less comfort.

The Problem Isn’t Always a Breakdown

One of the biggest misconceptions homeowners have is that if the AC is still running, everything is fine.

In reality, many systems lose efficiency gradually over time.

You may notice:

  • Certain rooms never fully cool down
    • The upstairs stays warmer than the rest of the house
    • The system seems to run nonstop during hot afternoons
    • Indoor air feels sticky or humid
    • Energy bills continue climbing year after year

These issues are especially common with older systems or systems that have gone years without maintenance.

When is it Time to Repair or Replace?

Sometimes a maintenance visit or repair is enough to restore performance.

Other times, an older system may be costing more in energy and repeated repairs than homeowners realize.

Today’s high-efficiency cooling systems are significantly more efficient than many older units still running throughout New Hampshire homes. In many cases, homeowners are surprised by how much quieter, more comfortable, and more affordable newer systems can be to operate.

Small Steps Can Make a Big Difference

Simple maintenance can often improve performance and lower cooling costs.

That includes:

  • Replacing filters regularly
    • Keeping outdoor units clear of leaves and debris
    • Scheduling seasonal maintenance
    • Checking airflow issues before the hottest part of summer arrives

The earlier problems are addressed, the better chance homeowners have of avoiding expensive breakdowns during peak heat.
