D.I.Y. Fixes and Repairs
1. Check for power to the equipment:
In our area, the rampant number of power failures and power outages can wreak havoc on your equipment. Be sure to check that the breaker or fuses aren’t tripped into the off position. Also, check the service disconnects for the equipment. If the equipment was running during a power outage or power surge, this is a great place to start.
2. Check the thermostat:
Try switching the settings of the thermostat to see if this is the problem. First, adjust the temperature setting either much higher or much lower than the current setting, and see if that fixes the problem. Also, try switching the system from “Heat or Cool” to “Off,” and then back to “Heat or Cool.” If that doesn’t work, try setting the thermostat to “Fan On” instead of “Auto” and see if the fan works.
The last thing to try is replacing the batteries in the thermostat. Most programmable thermostats, particularly modern models, require batteries—typically two AAs. You should be able to remove the thermostat from the wall and replace the batteries.
3. Check the filtration system:
The No. 1 cause for emergency repairs is neglect and dirt / dust. Be sure that you have recently changed or cleaned your filtration system. This is a very cheap way to keep your equipment operating problem-free.
Check with the manufacturer to find out how often your particular filter should be cleaned or replaced. Typically, 1” disposable filters should be changed every 30 to 60 days. 5” media filters every 3 to 6 months, and electronic air cleaners every 1 to 3 months, depending on the environment.
4. Check the pilot:
Most modern furnaces no longer have standing pilots that need to remain lit. However, this does still occur. Be sure that the pilot is lit in the furnace or hot water heater by looking into the burner section.
NOTE: This can be dangerous in the presence of gas and flame. High winds can easily blow pilots out.
5. Do you see water?
First, you want to isolate the source of the water. Go to the equipment and find out where it’s leaking from. If you can isolate the source of the problem, you can stop the water leak. Turn off the piece of equipment that is causing the leak, either at the controller, switch, or breaker. If you’re seeing water at a boiler or hot water heater, shut off the water supply into the equipment. This should stop the leak until help arrives.
What Makes Corcoran Unique:
Your Home is Your Castle Finding A Contractor Shouldn’t Be A Hassle…
Whatever its size or style, your home is your castle. You’ve worked hard for it, and maintaining it shouldn’t be a source of stress or hassle. With the right contractor in your corner, you can keep your home’s heating and air conditioning systems running smoothly and efficiently.
Are you tired of sifting through ads and coupons, clicking on countless websites, and trolling around consumer reports looking for answers to your heating and cooling questions? At Corcoran, we’ve created a documented, universal, and repeatable process for uncovering the art of heating and air conditioning services.
The Truth About Heating & Air Conditioning
Did you know that your indoor environment is 5 times more polluted than the outdoors? Or that your furnace and air conditioner deliver a mere 53% of the equipment’s capacity? In addition to sending your monthly utility costs and healthcare expenses soaring, your comfort system could negatively impact your quality of life.
Many heating and cooling products fail to reach their published efficiency. Adding to the problem, contractors are often installing those products with little or no training.

Our founder, Tom Corcoran, has lived and breathed HVAC and has worked hands-on in the trenches for 35 years—from an eager student to an expert instructor. Today, our diligent team custom engineers, installs, tests, and services each system to deliver the most BTU’S for the least possible investment.

Suspect Carbon Monoxide?
Exit the home leaving the exited door open to assist with fresh air.
Call 911 to have your home verified safe.
Contact Us to review the fire departments findings and discuss solutions.
If you suspect poisoning there is a blood test that can be done at doctors or hospitals that check the levels in your blood. Be sure to mention it to your medical professional as it is not a regularly used test. This ensures symptoms are not simply confused as the flu virus.
NOTE: Some store bought monitors alarm if they are in need of new batteries. If they are more than 5 years old they are in need of replacement. Consult the owners manual for specifics, but typically batteries should be replaced every 6 months.
