Hello Dan..........my name is XXXXX XXXXX I will be happy to assist you with your electrical question. My goal is to exceed your expectations on Just Answer!
1) The problem that you indicate is typically caused by "over-voltage". Over-voltage can either be caused by the local electrical utility transformer or the over-voltage may be smaller types of electrical surges that are occurring out on the utility distribution lines. Often, surges are storm related during strong lightening storms. Surges can also be attributed to the utility electrical distribution equipment and are not always caused by a lightening storm.
2) Do any of your neighbors experience similar problems with frequently replacing light bulbs? Ask the neighbors on your side of the street if they are experiencing similar issues.
3) Some light bulb manufacturers actually manufacture incandescent bulbs that are rated as 130 volts and not 120 volts to compensate for this problem. Incandescent bulbs are more prone to burning out prematurely due to over-voltages delivered from the electrical utility. All electrical utilities have a % voltage tolerance to deliver electricity. Even though your service is rated as 120/240, at any given moment in time, the voltage is constantly fluctuating. One second it will be 120 volts, next second down to 117 volts, next second up to 123 volts, etc. This changing occurs all of the time in any electrical distribution system.
You may also want to try changing light bulbs to CFL type or possibly a different light bulb manufacturer to determine if the problem stays or goes away. Although, since you are also experiencing problems with the fridge, I suspect over-voltage is the problem and possibly not the actual light bulbs.
4) Since you have also experienced problems with the Hydro, I would speak to your local electrical utility and request that they perform a power quality analysis at your service meter in order to determine that they are supplying you with the correct voltage levels and within the % tolerance. The utility has a power quality monitoring device that they can connect to your electrical main service for a 1 or 2 week time period and the testing device will record any voltage fluctuations. If the problem is on their end, it will most likely be with their transformer. There is no cost to you for the utility to temporarily install the power quality monitoring device. Explain to them the frequent problems that you have been having.
5) If your furnace is a gas model, it should be on its own dedicated 20 amp circuit and not shared with any other parts of the house. Check your main electrical panel circuit breaker and determine if the furnace is on its own dedicated circuit and not shared with the living room can lights.
6) You may also consider installing a whole house panel surge protector as well as local surge protectors on your expensive electronics. All it takes is 1 good strong surge and it can destroy thousands of dollars worth of sensitive electronic equipment.
