Heating Tip: Understanding the Safety Features on Your Furnace or Heat Pump

Monday, November 19th, 2012

One of the most important measures you can take as Peoria, AZ homeowner is to understand how to safely operate your furnace or heat pump. While there are the same basic types of safety devices on furnaces and heat pumps, there function differently for the different models. Knowing how these devices work on your specific model. Call Cool Touch if you have further questions.

Safety Features for Gas Furnaces

The main safety feature of gas furnaces is the limit switch, which shuts off the gas supply if it detects flames or heat outside the burner chamber. This device is typically located outside the chamber, and once it cuts off the gas, it will shut down the furnace until it is reset. Some furnace models feature controls that will display an error message or a manual reset button. If the limit switch has shut down the furnace, this button needs to be pushed before the furnace will turn back on; however, the reason for the limit switch locking out the furnace needs to be resolved or it will keep happening.

Heat Pump and Dual Fuel Safety Features

Heat pumps and dual fuel systems also feature a type of limit switch called the high-pressure limit switch. This device functions like the limit switch for gas furnaces, and it detects temperatures that are higher than normal in the airstream near the heat exchanger. It will shut down the backup gas furnace on dual fuel systems, but in the summer, the limit switch can accidentally get flipped under certain weather conditions, such as high air pressure.

More often than not, the limit switch on a heat pump shuts down the system because it got too hot due to improper airflow, which can be caused by a dirty or clogged air filter. If this happens often, these devices may eventually need to be replaced, and this is another reason it is important to change filters regularly. If you aren’t sure how to re-set your system, check the owner’s manual or call an HVAC technician.

Heating Tip: How to Choose a New Furnace

Monday, October 22nd, 2012

Are you thinking of purchasing a new furnace? Are you not sure what features to look for or how to get the most efficient furnace for your home? Whether you are in the market for a furnace replacement, or you are looking for the most cost-effective way to heat a new home, there are several features to look for to ensure that you get an efficient furnace.

Call the Scottsdale heating experts at Cool Touch if you want to know more about choosing the right furnace for your home. Here are a few things to look for as you start your search.

The first is the annual fuel utilization efficiency (AFUE) rating, or you can simply look for the Energy Star label to know whether you are getting a high-efficiency system. If you aren’t sure how to interpret the AFUE ratings, call a heating contractor with questions. All new furnaces should be rated above 80%, but if you want a high-efficiency furnace, look for ratings above 90%, which means that at least ninety percent of the fuel is being used for actual heat.

New furnaces will also have variable speeds so that the system can run at lower speeds for longer to help maintain comfortable temperatures more efficiently. Look for models that have multiple speeds for the fans. This feature is usually listed as a multi-stage furnace or variable speed fans. These multispeed furnaces are more efficient because the various fan settings use less energy to get the temperatures at the desired setting.

The last thing to consider besides the size and output is the condition of your ductwork and how well you home is insulated and sealed. We can help you determine this and size the furnace according to your square footage, number of windows, etc. If your ductwork needs improvements, this should be taken care of prior to the installation in order to get the most out of your new high-efficiency model.

Feel free to contact Cool Touch to discuss your options with one of our Scottsdale furnace specialists. We can help you select the right furnace for your home, and we’ll make sure that it is installed properly and maintained for years of efficient heat.

Furnace Tip: Common Furnace Repairs

Monday, October 15th, 2012

With routine maintenance, the furnace in your Sun City home is less likely to need repairs; however, there’s always a chance that something could go wrong, or perhaps your furnace is simply old and has more issues than it did in previous years. In any case, furnace repairs should be handled by a professional who is trained to work with this type of equipment.

Call Cool Touch for all your furnace repair needs. Here are a few reasons your furnace may need repair.

Cracked Heat Exchanger

If you own a gas furnace, always make sure you have a working carbon monoxide detector in your home in case of carbon monoxide intrusion. The heat exchanger is a common cause of this problem. When it is damaged or cracked, the waste fuel can seep into the living spaces. Your heating technician should always check the heat exchanger during any type of service. You can also routinely inspect your heat exchanger if you know where to locate it. Call a professional if you notice any damage, such as large holes, cracks, corrosion, or other issues. Newer furnaces often feature heat exchangers made of stainless steel and other durable materials to prevent this.

Broken Pilot Light

The pilot light on your furnace should always burn blue. If it is burning orange or yellow, you could have an issue. One way to check for other flame issues is to perform a flame test. First, you’ll need to shut down the furnace for about ten minutes or so, and have someone slowly turn up the thermostat as you watch the flame for any changes in color or flickering. If you suspect any issues, call a professional heating contractor. Gas furnaces should be repaired and maintained by a certified technician who is trained to work with gas-burning appliances.

Don’t hesitate to call the Sun City heating experts at Cool Touch if you have any issues or would like to schedule a furnace repair service.
