An Unresponsive Furnace

Posted on: August 16th, 2017 by Derek Barmer No Comments

Your furnace is one of the most important parts of your home and one of the most costly to repair. So what do you do when it appears to be broken?

If your furnace isn’t working, first try simply changing the filter. Often this is the issue. (This should be done at least once every few months– more often if you have allergies/asthma.)

You’ll also want to see if there is an indicator light on the furnace circuit board. If you see it and it is flashing, look for the chart that corresponds to it. This will tell you what is wrong.

Next, try cycling the power by turning the power off for five minutes and then turning it back on, either at the breaker or using the on-off switch on the furnace. This will reset the alarms in the system. You’ll turn the thermostat on and see if the system turns on. You’ll see the hot surface ignitor start to glow or hear the clicking of the spark ignitor. If the ignitor is not working, the gas valve will not stay open until your replace the ignitor.

Also, check that the gas did not accidentally get turned off.

Do not try to make any major repairs on your own, as this can void your warranty. Furthermore, it is always best to be on the safe side and call a professional if you are not comfortable with what you are doing.

You should already have a professional come twice a year to inspect and clean your HVAC system. Regular servicing will prevent the majority of problems from becoming huge!

Insulate with Spray Foam

Posted on: August 5th, 2017 by Derek Barmer No Comments

 

Fiberglass is a popular choice for attics and other spaces, but what if you’re thinking about spray foam insulation? It does cost more up front and may require some professional help, but it can perform as much as 50% better than fiberglass. Spray foam is also a moisture barrier and helps to dampen sound. How do you get started?

  1. If you decide to DIY, purchase a spray foam kit and wipe down the area you’ll spray. Make sure there is no water or debris.
  2. Cover electric boxes and connections.
  3. Check the temperature of the surface and the room, because adhesion and expansion of the foam are reduced by low temperatures.
  4. Put on eye protection, respiration gear, and protective clothing.
  5. Test your nozzle so the foam flows properly. After drying, rip a piece out and see that the inside is properly set and dry.
  6. Spraying close to your surface will cover a smaller area with more foam. Spraying further away from the surface will cover more of an area with less foam. Try to make as few passes as possible, because spraying onto wet foam can get messy and create an inconsistent surface. If you do end up needing to spray more than one layer, wait until your first layer of foam has cured.
  7. You can scrape away any cured foam that has covered the front of the wall studs.
  8. The kit can be used again—remove the used nozzle, remove the trigger safety, open both valves and make sure the face of the gun is clean. Stop using it when the foam starts to sputter and does not spray correctly.
