When you use an electrical appliance, the current flows from your service panel to the device. A grounded wire gives the unused electrical current a safe way back to the service panel so there’s no danger in the event of a short circuit.

When the electrical current that passes through a fuse exceeds the limit, it burns a hole in the thin strip of metal. This stops the flow of current and it means you have blown a fuse. Fuses need to be replaced (not reset). When the electrical current exceeds the limit through a circuit breaker, however, the breaker trip setting opens to stop the flow of current. Breakers are re-settable by flipping the handle on the face of the breaker.

First, make sure there are not too many appliances plugged into one circuit, as this can overload it. If it’s just one appliance, unplug it and either replace it or call us to repair it. You could also try connecting another appliance to the problematic receptacle. If it still shows signs of trouble, have the receptacle and or the circuit checked by our home electrical service experts

A surge protector is a piece of equipment that suppresses the excess voltage in your system to prevent it from causing harm to your appliances and devices. You should get some to protect your appliances and devices from power surges.

When you reach for your light switch to turn it off, only to find that it is hot to the touch, you have a problem. This is not a normal phenomenon, and it indicates that there are serious issues hiding behind your walls. If you don't get help right away, you could end up facing a serious electrical fire in your home.

Several years ago, the code was updated and it requires us to install arc fault breakers in the house wherever there are new lines being installed except for where GFCI devices are required (kitchens and bathrooms, etc.). This is a major breakthrough in our industry. This is one of the most intelligent breakers. They monitor the current and discriminate between normal and unwanted arcing conditions. Arc fault breakers are primarily designed to protect against electrical fires caused by arcing.

The most common plumbing problems are clogged drains and toilets, leaky faucets and pipes, water heater issues, low water pressure, and a running toilet. While most of these can be solved in a DIY fashion, some more serious issues will require a licensed professional to come out and assess issues with your current plumbing system.

The best way to prevent your pipes from freezing is by insulating your pipes. If you are not able to insulate your pipes you can leave the water on a slow drip on very cold nights. The water constantly running will prevent your pipes from freezing.

In short, no. Chemical drain cleaners can cause damage to pipes. The chemicals can cause degradation when used in old pipes repeatedly. When used in plastic pipes, chemical drain cleaners create heat which can damage the plastic pipes. In addition to possible damage to your home's plumbing system, chemical drain cleaners are bad for the environment and septic systems.

This is often the result of the handle getting stuck. This causes the flapper to remain open which will allow water to continue to flow into the bowl. Fixes could include tightening, lubricating, or replacing the handle.

The most common signs to tell if your plumbing system requires service include odd sounds coming from the faucets, low water pressure, unpleasant smells coming from the drains, sinks or tubs draining slowly, and stained or damaged walls.

Unless the homeowner requests a “contractor’s grade” of paint be used in order to save a few dollars, the homeowner should demand that a premium-grade paint is applied. The reason is that the cheaper grades of paint will often cause bleed-through after only a short time and simply will not stand up to normal wear and tear nearly as long as a premium grade of paint will. Also, put in writing ahead of time how many coats of paint will be applied.

Yes, this is normal. A heat pump generally produces air that is 80°, which is considered warm and will heat the house evenly. However, 80° may feel cool to your hand, which is usually closer to 90°.

You should have maintenance done on your air conditioning system twice a year. This not only ensures maximum efficiency but also enables us to foresee any possible problems that may occur shortly.

Changing out your air filter regularly is the primary maintenance you can perform. When talking about ground-mounted outdoor units the units will need to be kept clear of debris, which includes any foliage in the area. Additional maintenance should only be performed by qualified personnel.

For peak efficiency, performance and filtration, it is recommended that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month.

In general, no. HVAC systems are the least efficient when first turning on. A system with too much capacity will run in numerous short cycles, turning on and off repeatedly, therefore causing it to be less efficient and increasing energy consumption. Another primary function of an air conditioner is to remove humidity from the air and running shorter cycles doesn’t remove humidity from the air very well.

As a consumer the most important tasks you can perform involve cleaning and replacement of your filters regularly. Also, shades, drapes, shutters, or screens can be installed on windows that are exposed to extreme sunlight to help reduce temperatures as well.

HVAC systems use a metric called S.E.E.R. (seasonal energy efficiency ratio) when assessing efficiency. S.E.E.R. is the amount of cooling your system will deliver per dollar spent on electricity. For example, a 3-ton unit may have a S.E.E.R. efficiency rating of 13, 14, or 15. The higher the S.E.E.R., which ranges from 13 -17, the more efficient the system will be.

In general, one ton of air conditioning can cool anywhere from 300 to 800 square feet. The primary factor impacting the effectiveness of an AC unit is the construction of the home or building. The best way to assess your HVAC needs is to have a licensed professional perform an evaluation.

Heating and cooling systems are sized according to their tonnage. One (1) ton equals 12,000 BTU/H (British Thermal Units/ Hour).

HVAC is short for heating, ventilation, and air conditioning. The acronym is often used as an abbreviation to refer to your whole heating and cooling system.
