3 Common Furnace Repairs That Annual Maintenance May Prevent

Monday, November 3rd, 2014

Maintenance isn’t just a quick check of your heating system; it provides a tune-up for your entire heating system. During a routine maintenance appointment, your heating system is thoroughly inspected, cleaned and adjusted, and all moving parts are lubricated. In addition, small issues like worn fan belts and corroded wiring are fixed before they can cause bigger problems, which helps to reduce the need for furnace repair in Blaine. If you haven’t scheduled annual maintenance for your furnace yet, call Air Mechanical, Inc., today.

Repairs Maintenance Can Help Prevent

Maintenance can’t prevent all repairs, but there are some that can be avoided with consistent annual maintenance:

Fan Problems

The fan in your heating system has several components that, when left unattended, can fall into disrepair. Problems commonly detected and attended to with regular maintenance are: friction created by dry ball bearings in the fan shaft; loose or bent fan blades; loose motor mounts; worn fan belts; motor issues and electrical issues, including frayed wiring.

Burner

The components in your furnace can become dirty. When the burner is covered in a layer of dust and dirt, problems can develop, such as uneven heating, an inability for all the burners to light, and excessive wear and tear. During routine maintenance, the burner is inspected and cleaned, so that it can function optimally.

Ignition

Many of today’s furnaces light via electronic ignition. There are two types of electronic ignition: intermittent and hot surface. With both types, the igniters can become dirty. The fuel nozzle in the intermittent pilot can become clogged, which can block the gas from flowing. With the hot surface igniter, dirt on the outside of the igniter can act as insulation, and the igniter won’t become hot enough to light the gas jet. Part of routine maintenance involves cleaning the components, which helps prevent issues caused by dirt and grime.

Maintenance is good for you and your system. Help prevent repair with your furnace in Blaine this year by scheduling fall maintenance today with your Air Mechanical, Inc., expert.

Blaine, MN Furnace Repair: Clogged Air Filters

Wednesday, May 8th, 2013

Spring is a great time to ensure that your heating system works well. Whether you have a gas or electric furnace, it relies heavily on the air filter to ensure that dust and debris do not accumulate on sensitive mechanical components. If this occurs, your furnace will simply not be able to perform as it should, and it can result inadequate heating, decreased energy efficiency, and even premature system replacement. Thus, while a relatively easy task, it’s incredibly important to remember to change your air filter on a regular basis. When you need Blaine, MN furnace repair, call the experts at Air Mechanical today!

  • Blower motor fault. Your blower motor is responsible for blowing the heated air throughout your ductwork, after it has been heated by the heat exchanger. But when if you have a clogged air filter, then the blower motor will continue to work harder and harder until it overheats or breaks due to the increased load. By keeping your furnace air filter clean at all times, you can ensure that your blower motor is not undergoing any additional load.
  • Short-cycling. One of the most common issues related to a clogged air filter is short-cycling, which means when your furnace turns on and off frequently. When it cannot complete a heating “cycle,” your furnace will perform inefficiently, which can lead to a rise in energy costs. It will also increase the wear and tear on many of the system’s components.
  • Overheating. Your furnace is not enough. If it begins to overheat, it can cause all sorts of problems with operation. A clogged air filter causes your heated air to build up inside the air handler, leading to overheating. Temperature fluctuations can cause your heat exchanger to crack and this repair is both dangerous and costly!

Make sure you check and clean your furnace air filter about once a month during the heating season, and replace it when necessary. Operating your furnace with a clogged air filter only leads to problems. Call Air Mechanical today for comprehensive Blaine, MN furnace repair services!

Saint Michael Heating Repair Service: Inspecting Your Furnace Heat Exchanger for Leaks

Wednesday, January 25th, 2012

Like all the heating and cooling components in your Saint Michael home, your furnace needs regular maintenance and annual checkups performed by certified HVAC technicians. Here are some things that a professional heating maintenance technician can do to make sure your furnace is functioning safely.

One of the main concerns with any type of furnace is the potential for carbon monoxide gas leaks, which can be fatal if not detected. The heat exchanger is designed to prevent dangerous flue products from leaking into the home; therefore, it is important to inspect the heat exchanger for any cracks or excessive corrosion.

There are a few methods for introspecting a furnace heat exchanger for leaks and potential repairs (again, best performed by a professional HVAC technician):

  • Visual Inspection of the Furnace Heat Exchanger. Use a strong flashlight to visually check the heat exchanger thoroughly for cracks or open seams, particularly in areas that are susceptible heat or mechanical stress. Some seams may have been joined improperly during manufacturing, so be sure to check all joints. Also check for rust or corrosion in areas exposed to any type of moisture. Make sure you can gain access to all the parts of the heat exchanger. If you see any cracks, holes, or severe deterioration, your heat exchanger needs a professional repair. Ultimately, you may not be able to see all the parts of your heat exchanger, so further testing is recommended in addition to a visual inspection.
  • Flame Test. You can also observe the flame after the furnace is first turned on to detect potential damage to the heat exchanger. Turn off the furnace for at least five minutes, and sit close enough to the furnace to observe the burner flame. Have someone turn up the thermostat, and watch the flame for any changes in color or irregular patterns in the flame. If the flame makes any sudden changes, this could mean that the heat exchanger is damaged. Keep in mind that like the visual test, the flame test cannot determine damage to your heat exchanger alone.

In addition to increasing efficiency and lowering your heating bills, inspecting your furnace will ensure that your heating system operates safely throughout the winter. Along with having your heat exchanger inspected,  we recommend that you test all the carbon monoxide detectors in your home on a regular basis, as well as changing the filter every month and cleaning out the ventilation system.

If you need further assistance, or suspect any leaks in your furnace, you will need to schedule an appointment with a Saint Michael HVAC technician. Keep your home warm and safe this winter.

Circle Pines Heating Repair Question: What is a Gas Furnace Draft Hood?

Monday, January 23rd, 2012

As every Circle Pines HVAC contractor knows, a draft hood is a necessary part of any gas burning appliance. For a gas furnace in particular it ensures steady air flow to the burners to avoid flares or the pilot light being put out by fluctuation in temperature and air flow.

What the Draft Hood Does

The draft will change in the chimney as exhaust vents towards it – especially when going from cold air to hot. A draft hood is placed above the upper most part of the gas furnace to draw air into the chimney and makes it possible to draw more or less air through the chimney as necessary to create a constant flow.

This makes it possible for the burner to enjoy consistent air flow without any wind gusts or sudden temperature spikes or drops. Hot air, if not put through a draft hood would create a strong air flow through the burners.

A draft hood cools the air as it is released by the burners from 500 degrees F to between 300 degrees F and 350 degrees F. The cooling needs to be carefully calibrated to avoid condensation build up in the chimney however – a problem that occurs when the temperature gets too low.

Maintaining Pressure

The draft hood is a part of a larger system designed to maintain air flow to the chimney. For every cubic foot of gas burned, the furnace needs to have 15 cubic feet of air for combustion and another 15 cubic feet of air for dilution. A draft hood and the rest of the ventilation system make it possible to put a furnace that has many thousands of BTUs in the basement of your home and still supply it with enough air to burn gas and dilute the exhaust before it enters the chimney.

For all of these reasons, if you see your pilot light flickering irregularly, notice a backflow of exhaust or a burning smell in your furnace room, it’s important to call a professional who can inspect and repair the problem before it becomes any worse. Not only can gas burner exhaust contain high levels of carbon monoxide, it can be bad for the device and the chimney if it doesn’t vent properly.

Furnace Repair Guide: Furnace Air Temperature

Friday, January 20th, 2012

When your furnace turns on every day and warms your Chaska home, just how hot is the air being blown through your vents? It’s a common question and while it varies depending on the type of furnace you have and the length of your ductwork, normally, the air is about the same temperature in most homes.

The Heating Process

When you turn on your furnace, it ignites fuel (gas or oil) or heats elements (electricity). A blower fan blows air through the heat exchanger and then into ductwork that distributes the heated air to vents around your home. When the combustion occurs and air is first heated, the temperature is between 140 degrees F and 170 degrees F.

This is extremely warm and could be dangerous to anyone if they got too close to it or it was blown directly into your home. However, as the heated air is distributed into your home it starts to cool. In some cases, it loses a significant amount of its energy in the ductwork.

This is intended, of course, because the temperature would be much too high if it was distributed directly to your rooms. That’s why high velocity ductwork often requires regulation to avoid overheating of the air. Cooling like this is normal and results in a better, more evenly distributed airflow.

When Something’s Wrong

To know something is wrong with your heating system, you must first understand what temperature air normally is when distributed through the vents. This will vary depending on which room you are in and how big your home (and furnace) are. However, if you notice a sharp drop off in comfort level in your home, it takes longer to heat rooms when cold or if that heating is suddenly uneven, it may be time for someone to inspect your furnace and check for potential problems.

A technician will then check to see if the air is being heated to the target 140-170 degrees F or if heat is being lost in the air handler or ductwork. There are a number of issues that can contribute to lost heat in your heating system – the easiest way to be sure the problem is solved properly is to call a Chaska professional when you notice the problem.
