Why Won’t the Backup Heat Turn on in My Dual Fuel System?

Wednesday, February 25th, 2015

A dual fuel hybrid system offers you the ultimate in heating power and energy savings. These systems combine the energy efficiency of a heat pump with the power and reliability of a gas furnace. For most of the days that you need heat, your heat pump will be the primary form of heating. This system also doubles as an air conditioner, moving heat out of the home in the summer and into the home in the winter. This is an efficient heating system because moving heat around uses less energy than generating it. But when outside temperatures dip too low, your furnace should kick in.

Not feeling any heat in your home? Check out our guide to find out why the backup heat is failing, and call the friendly technicians at Cool Air Mechanical for heating repair in Alpharetta.

Thermostat Programming

When the technician installs your dual fuel system, a thermostat must be set to recognize when the furnace is needed. If the programming is faulty, or if the thermostat has encountered some wiring issues, the backup heat may never turn on. Be sure to call on experts for installation and maintenance to prevent this from happening.

Furnace Trouble

Of course, it may just be that your furnace is not functioning properly at all. If your furnace won’t turn on or if it won’t stay on, it could be due to a safety switch that keeps it from operating if there is a potential for leaks. Or it may be a broken blower fan, burner trouble, or ignition failure. For your safety, be sure to leave any of these repairs in the hands of professionals.

No Need

Perhaps the reason your backup heat has not kicked in is because there is no need for it to switch over. If your outdoor unit is still running in very cool weather, don’t be alarmed. The balance point for a dual fuel system is relatively low. If you still don’t feel any heat, you may have a problem with your heat pump. Try switching over to cooling mode. If this doesn’t work, the heat pump is likely the culprit.

Contaminants Sometimes Found in Air Ducts

Wednesday, February 18th, 2015

The first home HVAC system air filters were actually designed to keep particles out of the air handler of the heating and air conditioning equipment. If large particles were to move from the air in your home into the blower fan, it could hinder performance, causing the fan to slow down and potentially jamming the motor. Dust can also clog the burners of a furnace or keep the air conditioning coils from absorbing heat effectively.

Just like the air filter in your car, the air filter in your air conditioning and heating system protects the parts of your unit from damage. But today’s filters serve a second purpose, eliminating unsafe particles from the air that you breathe. Because air cycles frequently through the ducts, it’s important to have some form of defense against pollutants that could aggravate allergies and irritate the lungs.

But a standard air filter doesn’t guarantee that all of the contaminants that could enter the ducts are deterred. In fact, most home air filters are ineffective at removing even the most common home contaminants, such as mold spores, which could then move into the ducts. Many of these contaminants stay dormant in the ducts for a while, infiltrating the home from time to time and irritating household members’ allergies and other respiratory conditions.

The following contaminants may be contained within your duct system. Experts recommend scheduling duct cleaning once a year in some cases, or as often as your technician recommends it.

  • Dust mites: Dust mites thrive in warm, humid areas, and the ductwork may be a perfect location. As one of the most common allergens found in homes, dust mites can irritate those with allergies and may even trigger asthma in children.
  • Pet Dander: You may not have a pet in your home due to your allergies, but what about the homeowners who came before you? Duct cleaning is especially important for people with severe allergies, especially if they seem to act up often.
  • Bacteria: There could be some harmful bacteria present in the ducts that could make family members ill, particularly those with immune disorders.
  • Mold: Finally, mold survives on wet surfaces, like the indoor air handler of your air conditioning system, and could spread to the ducts.

How Rust Can Develop on a Furnace

Monday, February 16th, 2015

Rust on your furnace is akin to a jet engine on a car: it just shouldn’t be there. In fact, it’s not good to have rust on a boiler, and that’s a system that uses water to heat. Rust on your Atlanta furnace means that there is a moisture problem somewhere, and once rust starts, it’s very hard to stop it. If you see rust on your furnace, even a small spot, it’s time to call your technician from Cool Air Mechanical and schedule an appointment.

How It Starts

There are a few ways in which rust can start to develop on your furnace. The first way is from the improper ventilation of the water vapor created during combustion. The way it happens is this: the toxic byproducts created during the combustion process enter the inside of the heat exchanger from the bottom and make their way to the top of the exchanger where they exit via the flue. As the vapors travel, they cool, and condensation is created. If your furnace isn’t vented properly, this condensation can linger on the metal of your heat exchanger and flue, and rust develops.

A second way rust can develop is if you have a combination furnace and air conditioner HVAC. With these kinds of units, the air conditioner evaporator sits on top of the furnace; sometimes condensation that develops while the air conditioner cycles drips down and lands on the furnace components, and rust develops.

The last way rust can develop on your furnace is via faulty ductwork. Faulty ductwork can allows excess moisture to enter, and this excess water can run down the ductwork to your furnace. Improperly installed ductwork can also allow rain water in, which will also run down to your furnace.

Sometimes if the rust is located in a specific area and the amount of rust is small, there is a chance that particular spot can be remediated. Unfortunately, if you have excessive rust on your furnace, you may need to consider replacement. Get ahead of even the smallest amount of rust by scheduling a repair appointment for your furnace in Atlanta.

Some of the Unusual Movies Released for Valentine’s Day

Saturday, February 14th, 2015

Hollywood has always tried to match movies up to the seasons to draw droves of viewers to the theaters: October is packed with fright-offerings, while the winter holidays skew toward warm and pleasing family films (as well as Oscar hopefuls). Valentine’s Day falls in an odd spot when it comes to the movie release calendar, however, since February tends to be a slower time for the film industry. The studios are as likely to slot strange movies that don’t fit anywhere else in their annual schedules into the Valentine’s Day weekend as they are films with powerful romantic appeal.

So, while the second weekend of February has featured hugely successful romantic comedies like Hitch, The Wedding Singer, and (of course) Valentine’s Day, some truly weird choices have debuted in this weekend as well. And a few have even gone on to tremendous success despite the bizarre match with the holiday. Here are a couple of the odder Valentine’s Day movie releases:

  • Dracula (1931): Yes, this Halloween perennial and the start of Universal Studio’s Classic Monsters actually came out on Valentine’s Day! But perhaps this makes some sense, as the Dracula legend has often received a “doomed lover” approach in the many years since Bela Lugosi made the aristocratic vampire a screen icon.
  • The Silence of the Lambs (1991): Does any film seem less appropriate for Valentine’s Day than this unnerving and sometimes very violent psychological thriller? What’s even more astonishing than the film’s release date is that The Silence of the Lambs eventually nabbed the Oscar for Best Picture, an almost unheard of occurrence for a movie released so early in the year.
  • Daredevil (2003): This Marvel comic adaptation featuring Ben Affleck as a blind superhero does contain a romantic subplot, but the stronger connection to Valentine’s Day may just be that Daredevil wears a bright red costume.
  • A Good Day to Die Hard (2013): The least successful of the Die Hard film franchise, this is an excellent example of a studio dropping a film into a weekend where it doesn’t fit in the hopes that it works as counter-programming. (It didn’t.)
  • Wayne’s World (1992): Now here is an example of counter-programming that clicked with audiences. This comedy based on a Saturday Night Live sketch turned into one of that year’s biggest hits and spawned a sequel.

Whether you celebrate Valentine’s Day with a trip to the movie theater, or you have your own special plans, everyone here at Cool Air Mechanical
hopes you and your loved ones have a wonderful weekend.

How Long Can I Delay Heating Repair?

Wednesday, February 4th, 2015

To be honest, if you think that your heating system needs repair, you shouldn’t delay it at all. The longer you delay heating repair for a malfunctioning system, the more damage you’re likely to cause. In some cases, waiting to address a heating system’s problem can lead to a complete breakdown. Instead of delaying heating repair because you don’t want to deal with it, you should adopt practices that lessen the frequency of heating issues. Let’s take a look at some of the things you can do to keep your system healthy, and reduce the frequency of heating repairs.

Schedule Annual Maintenance

The most important thing you can do to preserve the health of your heating system is to schedule annual preventive maintenance. Having your heating system checked out at least once a year, regardless of whether or not it is having issues, will help ensure that your system is in top physical condition. Any parts that are starting to malfunction can be identified and replaced before they start causing major issues. This kind of maintenance is so helpful, in fact, that many warranties on heating systems require it in order to stay valid. So, if you really want to keep your heating system healthy, don’t wait for it to start showing signs of distress. Schedule preventive maintenance at least once a year.

Don’t Ignore Problems

Not all issues with heating systems will provide any sort of warning sign, but many of them do. If you have reason to believe that your heating system isn’t working properly, schedule a maintenance call immediately. Strange noises coming from the heating system are very common indicators of a problem, as well as uneven heating across the house and higher heating bills. Though having to deal with a maintenance call may be annoying, ignoring the problem for any length of time only increases the likelihood of the problem developing into something much more damaging and expensive. Don’t delay, call a professional as soon as you notice unusual behavior from your system.

If you need heating repair, schedule an appointment with Cool Air Mechanical today. We provide professional heating repair services in the Marietta area.
