We’ll help you safely rule out simple fixes, spot true emergencies, and know when to call. Members of Paul The Plumber’s Promise Plan get after‑hours emergency access and next‑day guarantees. Keep reading for quick steps you can do right now and what to expect from a pro.
Safety First: Stop Damage, Stay Cool
When an air conditioner suddenly dies, start with safety. Turn off the system at the thermostat. If you notice a burning smell, smoke, tripped breakers that will not reset, water pooling around the air handler, or loud clanks at startup, cut power at the breaker and call a professional. Heat and humidity build quickly in Southern New Hampshire during July and August. Protect medicine, pets, and electronics. If indoor temps are rising fast, move to a cooler level of the house, close blinds on sunny windows, and run ceiling or box fans for circulation.
"I called Paul the plumber for an emergency drainage issue at our home. The technician Tyler was extremely friendly. Found the problem and fixed it right away. I would highly recommend services from them again."
Quick Reset: Thermostat and Power Checks
Most no‑cool calls start with control problems. Confirm the thermostat is set to Cool and at least 5 degrees below room temperature. Replace the batteries if it uses them. Toggle the system Off for 60 seconds, then back to Cool. Next, check your electrical panel. If the AC breaker is tripped, reset it once by switching fully Off, then On. If it trips again, stop. Repeated trips signal an electrical fault that needs a licensed tech. Also inspect the emergency shutoff switch near the indoor unit. Someone might have bumped it while storing boxes.
"I called Paul The Plumber out as an emergency service due to the wiring of my blower not working properly.. They came out earlier than quoted fix the problem quickly they were very knowledgeable, polite, friendly, and professional."
Airflow First Aid: Filters, Vents, and Returns
Restricted airflow makes systems overheat and shut down. Pull the furnace or air handler filter and hold it up to light. If light barely passes through, replace it. In summer, a clogged filter can freeze the evaporator coil and stop all cooling. Open at least 80 percent of supply vents throughout the home. Check that return grilles are not blocked by furniture. In older colonials and capes around Nashua and Manchester, closed basement vents can starve upstairs rooms. Restoring airflow can restart cooling within an hour if the coil was beginning to frost.
"Mike did an awesome job fixing a whole list of issues in a pretty timely fashion. Called today and got everything fixed same day, wasn't even an emergency call! Thank you."
Outdoor Unit Inspection: Give the Condenser Room to Breathe
Head outside. Make sure the disconnect box near the condenser is fully seated and On. Listen for the fan and compressor. If it hums but does not start, there may be a failed capacitor or contactor. Clear debris from the top and sides. Maintain at least 24 inches of clearance. Pollen, cottonwood, and leaves common in Southern NH can mat the coil and cause high pressure shutdowns. Gently hose the fins from inside out if the power is off, or schedule a professional coil cleaning for a deeper flush.
"Amazing emergency service. Caleb was very prompt with same day service. He was very professional and explained everything Could not have asked for more!"
Frozen Coil Clues: Frost, Drips, and What To Do
If you see frost on the refrigerant lines or a block of ice on the indoor coil, turn the system Off and set the fan to On for 60 to 90 minutes. Open vents and replace the filter. Do not chip the ice. Running the fan helps melt it safely. Freezing usually points to low airflow or low refrigerant. After thawing, try cooling again. If it refreezes, you need a service visit to check for leaks, airflow issues, or a failing blower.
"Furnace boilers work and cleaning . Highly recommend this company . Also signed up for yearly service plan and emergency service."
Water Where It Shouldn’t Be: Condensate and Breakers
Water around the indoor unit often means a clogged condensate drain. Many systems have a float switch that shuts cooling off to prevent overflow. Check the drain pan under the coil. If full, turn the system Off. You can try clearing the line with a wet‑dry vacuum at the exterior drain, but avoid harsh chemicals. If breakers continue to trip when cooling tries to start, stop and call a professional. Electrical faults are not DIY.
"They came out earlier than quoted, fixed the problem quickly, and were very professional. Highly recommended."
Know When to Call: Signs of a True AC Emergency
Call a licensed HVAC pro right away if you have any of the following:
- Breakers that continue to trip.
- Water around the unit or active overflow.
- Burning smells, smoke, or scorching near the air handler.
- Loud bangs, grinding, or screeching every time it runs.
- No cooling during a heat advisory with vulnerable occupants.
At Paul The Plumber, approved emergency indicators include “THE BREAKERS CONTINUE TO TRIP,” “WATER AROUND THE UNIT,” and “LOUD SOUNDS EACH TIME IT RUNS.” These are not wait‑and‑see issues.

DIY You Can Try Safely Before We Arrive
If the system is safe to run and not tripping breakers or leaking, these steps may restore cooling or buy time:
- Replace the air filter and open all supply vents.
- Set the thermostat to Cool and fan to Auto. Replace thermostat batteries.
- Power cycle the system Off and On at the thermostat. Reset a tripped breaker once only.
- Clear leaves and debris from the outdoor unit. Restore 24 inches of clearance.
- Thaw a frozen coil by setting the fan to On for 60 to 90 minutes.
- Vacuum a suspected condensate drain clog from the outside termination with a wet‑dry vac.
Stop immediately if you smell burning, see arcing, or the breaker trips again.
When Repair Becomes Replace
If your AC is 12 to 15 years old, uses R‑22 refrigerant, or has a failed compressor, replacement may be the smarter move. Heat pumps are a flexible option in Southern NH, delivering efficient cooling in summer and heat in the shoulder seasons. We provide load calculations, duct inspections, and rebate guidance. Promise Plan members receive priority scheduling and extended warranties that protect your investment.
Prevent the Next Breakdown: Maintenance That Actually Matters
Annual maintenance reduces surprise breakdowns, keeps energy bills in check, and protects warranties. Our tune‑ups include coil cleaning, electrical testing, refrigerant checks, drain clearing, and thermostat calibration. The result is steadier comfort during humid New England heat waves. Paul’s Promise Plan adds Priority Service, Extended Warranty, and Exclusive Savings. Members also receive emergency access until 10 pm, seven days a week, with guaranteed next‑day service for calls after 10 pm.
Local Insight: Southern NH Homes Have Unique AC Stressors
Cape‑style homes in Manchester often have undersized returns on the second floor. Split‑levels in Derry and Londonderry can struggle with airflow balance between levels. Shoreline humidity in Portsmouth accelerates coil fouling. In Nashua and Merrimack, cottonwood and pine pollen can clog outdoor coils in June. If your home matches any of these, the airflow and outdoor coil steps above are doubly important, and a maintenance plan will pay for itself quickly.
