Troubleshooting Common Electrical Problems in Your Home

Household electrical malfunctions can cause dangerous situations to occur in your home. Flickering lights, malfunctioning appliances, and bad wiring can all be signs of electrical problems in your home. Although it is always safer to call a professional to deal with your electrical repairs and replacements, here are some electrical troubleshooting tips for common household electrical problems.

Frequent Electrical Surges - Try removing cheaply made devices or devices that use a lot of power from your power outlets.
Frequent Circuit Breaker Trips - Pay attention to the appliances in use when your breaker trips. For hairdryers, try using the low setting and try not to use two high-power consuming appliances in one outlet.
High Electric Bill - Identify electric devices that cause power surges, unplug appliances and charges when not in use and repair damaged wiring or circuits.

Have been using Cardinal since furnace installation some years ago. We have always been satisfied with the quality of their work and suggestions for how we can keep the furnace in good working condition. I do feel we get good value for the money.

We asked the technician to check whether our water heater was damaged at all as a result of a laundry tub filled with water overflowing and spilling onto the basement floor. We also had the tech evaluate the noise created by turning on the faucet in our guest room bathtub. The tech’s analysis indicated neither issue required any repair.

Paul did a great job going over our system and explaining the problems we were having and how to fix them. We have a really old system anyway, but there was a lot of diy that had been done that he picked up on that we were never told about when we bought the house.

My wife and I built a house six years ago and had another HVAC company install our heating and cooling. We have had nothing but trouble since with little to no help from the installers. Finally our AC went out on a 90 degree day on the weekend and we called Cardinal even though we have never used them prior they came right out and in a very timely manor replaced our broken unit. Fast forward to this last Friday night our Furnace stopped working. We called Cardinal and they were our at 7am Saturday and had the part we needed ordered and fixed by Monday. Defiantly wish we used Cardinal in the first place when we built.

Excellent work. Technician was wonderful! Highly recommend this company. They came in a timely fashion. Most other electric companies couldn’t make it until November. I needed an immediate response and Cardinal delivered and then some. The technician Ben was great! Very nice and easy to talk to. Was willing to go buy parts for me. I will definitely call Cardinal when I need electric repairs. Ben especially needs a high five for his work and professionalism.
