If you've lived through a summer in Middleborough, Bridgewater, or Taunton, you know how unpredictable—and intense—the weather can be. Heatwaves, sudden thunderstorms, and high humidity don’t just impact your comfort—they also put serious strain on your home’s plumbing and air conditioning systems.

At RCL Mechanical, we’ve seen how extreme summer weather in Southeastern Massachusetts can lead to unexpected problems in homes throughout Raynham, Norton, Lakeville, Attleboro, Wareham, and Mansfield. Here’s how your systems are affected—and what you can do to stay ahead of the damage.

1. High Temperatures Push AC Systems to Their Limits

When outdoor temperatures climb above 90°F for several days in a row, your air conditioner has to work overtime. Even well-maintained systems can struggle to keep up with demand.

Common AC issues caused by extreme heat:

• Low cooling output or uneven temperatures

• Refrigerant leaks due to pressure buildup

• Dirty coils causing poor airflow

• Blown capacitors or tripped breakers

In homes with undersized or aging systems, the risk of failure increases dramatically during prolonged heatwaves.

2. Humidity Makes Cooling Less Efficient

Summers in Bristol and Plymouth counties often come with high humidity levels. Humidity makes the air feel warmer and forces your AC to work harder—not just to cool the air, but to remove excess moisture.

If your system can’t handle the load, you may notice:

• Sticky, clammy indoor air

• Foggy windows

• Mold or mildew buildup in ducts or filters

Routine HVAC inspections and coil cleanings can improve dehumidification and reduce strain on your unit.

3. Heat Can Damage Outdoor Plumbing

Hot temperatures and dry ground conditions can affect your outdoor plumbing and irrigation systems. As the soil expands and contracts, it can shift underground pipes, increasing the risk of cracks and leaks.

You may also notice:

• Low water pressure in outdoor spigots

• Dripping hose bibs or faucets

• Higher-than-normal water bills

If your home has older pipes or uninsulated outdoor lines, it's especially important to monitor for signs of wear during a hot, dry summer.

4. Sudden Storms Can Overwhelm Your Drainage System

Heavy summer downpours are common in Massachusetts, and they often hit fast. When gutters and sump pumps can’t keep up, water can back up into plumbing lines, causing:

• Clogged or slow drains

• Sewer odors

• Basement water damage

Scheduling a professional plumbing inspection before storm season peaks can help identify potential blockages before they become emergencies.

5. Summer Is the Perfect Time for Preventive Service

At RCL Mechanical, we recommend scheduling:

• Mid-season AC tune-ups

• Drain inspections and water pressure checks

• Sump pump and outdoor plumbing maintenance

• IAQ assessments for mold, allergens, and humidity

Staying proactive can help avoid expensive repairs, improve energy efficiency, and keep your family comfortable and safe all season long.
