Why Is My Furnace Making a Strange Noise?

Monday, September 23rd, 2013

If you have a furnace in Andover, MN, you don’t want it to fail during one of our harsh cold winter days. If your furnace starts making unusual noises, it might be a warning sign of trouble. You probably know what sounds to expect from your furnace when it’s operating normally, so anything out of the ordinary needs your attention. If your furnace requires repairs, turn to the professionals at Air Mechanical Inc. We’ve serviced heating troubles since 1985 with our large and skilled staff, and can service your furnace in Andover.

Here are some reasons your furnace might have started to make odd noises:

Dirt build-up: If too much outside contamination gets into a furnace (usually because of problems with the air filter), it can damage the working parts and make it noisier. Dirty gas burners will cause a low rumbling noise. Ball bearings that need more lubrication will create a high-pitched squeal. The furnace will probably require a thorough cleaning, and the filter will need to be changed.

Failing motors: If a motor is overworked and has not received proper maintenance, it can start to burn out. If you hear a humming noise from your furnace, it could be a motor that is about to die—leaving you with a non-functioning heater. Get a professional in right away to find out if the motor is the culprit and needs replacing.

Gas leaks: If you have a furnace powered by natural gas, pay special attention to any rattling sounds coming from it. This might indicate a carbon-monoxide leak due to cracks in the heat exchanger. This is an urgent issue and needs an HVAC technician to remedy it immediately.

It is very important that you do not attempt repairs on a furnace on your own unless you have expertise in HVAC technology. Furnaces are complicated machines, and tampering with them can lead to electric shocks or exposure to hazardous fumes, depending on its power source. Have professionals analyze the problem and make the necessary repairs when you suspect those noises are a serious issue.

When you don’t like the sounds your furnace in Andover has started to make, contact Air Mechanical Inc for the expert help you’ll need to keep safe and warm.

Common Furnace Repairs You May Eventually Need

Wednesday, September 18th, 2013

No one ever wants to have their heating system break down, but eventually it will happen. Your furnace uses a number of different moving parts that can run into problems. Here at Air Mechanical, we’ve responded to countless calls for furnace repair and we wanted to put together a few of the most common ones that we see. Give us a call for all of your Andover heating repair services.

Andover  Heating Repair Tip: Common Issues

No matter what type of furnace you have, it will eventually run into problems. Here are a few of the most common you may eventually encounter.

  • Clogged air filter – Probably the most common cause of furnace issues is a clogged air filter. Your furnace uses an air filter to keep large contaminants like dust, dirt and insect parts out of the system. If it gets clogged it will restrict the flow of air into your system and cause it to have to work harder to pull in air. This will reduce your comfort and reduce the efficiency of the system as well.
  • Not enough heating – Insufficient heating is another common problem that is often caused by a clogged air filter. However, it could also be that your furnace’s burner is out, that the thermocouple is faulty or that the fan motor is broken.
  • Noises – If you have a gas-fired furnace pay attention to any rattling noises that you might hear. Rattling can sometimes indicate that you have a crack in your heat exchanger which might be allowing carbon monoxide to leak into your home. Also, squealing is usually caused by a bad fan motor belt; rumbling can be caused by unburned fuel in the combustion chamber.

Whether you have a natural gas, propane or electric furnace, call the Andover heating repair experts at Air Mechanical. We will make sure that your system gets repaired quickly so that you can get back to enjoying the comforts of your home.

2 Heating Services to Consider Scheduling Before Winter

Monday, September 9th, 2013

The Minnesota winter is almost proverbial throughout the country for how cold it can get—and it’s going to be on us sooner than we think. You rely on the heating system in your home to make those long months tolerable, so don’t take any chances. To stay snug and cozy this winter, you should consider having certain crucial services done on your heater before the big cold hits. Heating technicians have busy schedules during winter helping people with emergencies, so take advantage of the slower fall season to contact the Andover, MN heating service experts at Air Mechanical Inc.

Here are two services you should get taken care of before the cold spell:

Change your air filters: If you use a furnace to heat your house, you need to make sure you have a fresh filter ready for the winter. The filter protects your furnace from airborne debris. When winter starts, you will need to change the filter at least once a month, but make sure that you don’t start out the icy season with a dirty filter that could lead to damage as well as a reduction in air flow and a drop in air quality.

Schedule a maintenance check: Whether you use a boiler, furnace, or geothermal heater to provide warm air for your home, you should have a professional HVAC technician examine it to make sure it will perform to the standards you need for winter and reduce the risk of a costly and uncomfortable breakdown. A professional will notice difficult-to-spot problems in your system, such as corrosion in the ducts or inefficient heating. We recommend an annual maintenance visit—and the fall is one of the best times to schedule one, since it will give you ample time to get any necessary repairs done.

Don’t leave something as important as your heating system to an amateur. Only professionals should take care of these services to prevent breakdowns during the most inconvenient of times. Air Mechanical Inc. has a quarter of a century of experience performing heating services in Andover, MN. Contact our NATE-certified technicians today to get a head start on the winter weather.

Why We Celebrate Labor Day

Monday, September 2nd, 2013

We wish our present and future customers a pleasant Labor Day this September. We know how hard you work to ensure that you and your loved ones have a good life, and we feel the same way about the work that we do throughout the year. Home comfort is our business, so you can rely on our technicians to take care of any issues that you may have. To us, Labor Day means BBQ, the start of the football season, and spending quality time with our friends and family.

Like many US holidays, the origins of Labor Day are somewhat disputed. While many cite Peter J. McGuire’s (of the American Federation of Labor) suggestion of a demonstration and picnic as the inaugural Monday, others cite Matthew Maguire, then secretary of the Central Labor Union of New York. In the wake of the massive and violent Pullman Strike of 1894, which pitted George Pullman and US Marshals and Military against workers of the Pullman Palace Car Company outside Chicago. Designated as a federal holiday by Congress and President Grover Cleveland in 1894, a mere six days after the strike ended, Labor Day has since become a way of recognizing the contribution that hard working Americans have made to this country.

We wish you all the best this Labor Day. Make sure that you take the time to relax, eat some good food, and take a load off.
