FIX it FRIDAY: What's wrong with my furnace

What’s Wrong With My Furnace?


When heat comes on, lights go dim

by Paul Bianchina

Q: We recently moved into a home with electric forced-air heat. In the winter, every time the furnace kicks on, the lights in the house dim for a nanosecond. Is this something that can be addressed or fixed?

Before we moved in we had to replace the electrical panel (it was made by a company that went out of business years ago because their panels were known to start fires), and I’m wondering if there is something associated with that we can correct. Any help before furnace season starts is greatly appreciated! –Lea


A: The dimming of the lights is caused by a voltage drop that occurs during the startup phase of the furnace. When your thermostat calls for heat, the electric elements in the furnace begin to heat up before the furnace motor kicks on, a process called “heat anticipation.” It’s set up that way so that the furnace fan doesn’t blow cold air through the ducts before the furnace itself heats up. So when you hear the furnace kick on, that’s actually the sound of the fan motor starting up and activating the fan itself.

A couple of possible problems come to mind: The wires leading to the furnace may be too small, or you may have a loose or corroded connection. There should be two circuit breakers on the furnace itself, and they may be loose or faulty. It’s also possible that the furnace motor is going bad, or that you have some problems with the fan, the belts, or other internal furnace parts that are requiring an excessive amount of electricity in order to get turning.

Given the fact that the panel was replaced recently, you definitely want to have an electrician come out to inspect everything — the new panel, the circuit breakers, wire sizes, connections (including the connection to the utility company wires), grounding, etc. All this should be covered under the one-year warranty from the electrical contractor who did the work. I would also strongly recommend that you have the furnace checked and serviced by a heating company that deals with your particular brand of furnace.

One other thing: Since the electrical panel was replaced recently, your local building department will have a record of the permit. I would suggest that you obtain a copy of that, and make sure that the installation was inspected and approved and that the inspector didn’t note any problems.

Leaky Roof: Where to find the problem and the solution by Jay Dee

So your roof is looking a little shabby and you are wondering when it's time to replace your roof. There are some places on your roof you can check, they tend to be the weakest points on the roof due to high volume of water or trees covering a section of a roof.

Asphalt shingles are a large blanket covering an area of a lot of moisture. Over the years it is quite common especially with bad ventilation to notice that the shingles curl upwards. Over the years the moisture need to find a way out, when the heat softens the asphalt the shingles actually go against gravity and curl upwards, cedar shake has a tendency to do this as well. over time the curling cause the shingles and shakes to split and crack. It generally takes three in a row to split vertically and trouble will begin.

Chimney and skylights over time have the ability to accumulate debris and moss growth around the base where they meet the roof. generally behind the chimney or skylight enough debris accumulates for the water to dam up and push the flow against gravity up a shingle and into the attic. you could stop this leak by cleaning around the flashing and making sure that water has a clear path towards the eaves trough.

Valleys are the area on a roof where two angled roofs meet and is also a point on the roof that has the most water running along it. Using steel in valleys is a common but new practice with the majority of the roofs have knitted shingles in the valley. Shingles are strong against the elements but are not designed to deal with that kind of flow of water. Valleys are probably the biggest reason roofs leak.

Rental Property Quick Fixes

by Michael Monteiro

When it comes to tiny property repairs, a molehill can very easily become a mountain if it’s not resolved quickly.
Whether you’re a DIY kind of person or would prefer to have a contractor or handyman take care of your property’s repairs, time is of the essence.
Not only is it important to take care of repairs and maintenance quickly for your tenants’ sakes, but also for your bank account’s. In so many cases, a little problem that goes unaddressed can turn into a big, expensive problem not so far down the line.
Budget for the unexpected.
Setting money aside for those unexpected repairs that always come up sooner or later is one of the smartest moves you can make as a landlord. No matter how good your intentions are, it’s almost impossible to move on any repair quickly if the funding simply isn’t there.

Move quickly, no matter how innocent an issue appears.
Cracked plaster? Leaking roof? Chipped window? All of these are examples of “little” issues that are easy to set aside, but will only grow with time. Cracked plaster can easily begin to crumble, resulting in a much bigger mess. A leak can expand and run rampant, causing significant water damage. A tiny window chip can quickly spread, leaving no other option than a complete window replacement.

Maintenance and small repairs go hand-in-hand.
There are some maintenance duties that count just as much as repairs, and should be performed just as efficiently. Cleaning gutters on a bi-annual basis, for example, is critical. Sure, it may not seem like the most pressing job, but you’ll save yourself a lot of money in the long run. Other regular maintenance work that staves off big repairs includes: draining your water heater (once a year); cleaning stove grease filters (every time a tenant moves out); and turning off the water for exterior water faucets (every year when the temperature dips below freezing).
Keep the basics on-hand.If you choose to take the DIY route when it comes to repairs and maintenance, make sure you have the basic tools you’ll need to complete a range of tasks on-hand. You’ll be much more likely to take care of things quickly if everything you need to do it is easily accessible.

Have a professional in mind ahead of time.
Much as it pays to budget for problems before they happen, it also pays to research handyman and contractor options ahead of time. If you already know exactly who the man for the job is, you won’t have to waste any time once the need for a repair crops up.
Repairs don’t have to be a big deal. But they may well become one if not addressed in a timely manner. Having a plan of action in place before repair items ever arise and a no-holds-barred attitude about addressing them immediately is a great way to save yourself a lot of money in the long-run.
