The flue on your furnace is designed to vent carbon monoxide and other gases made during the combustion process outside. If the flue is clogged or damaged, it can't do its job, and this puts you and your family at risk. Every vented heating appliance in your home should be inspected and cleaned regularly to prevent carbon monoxide poisoning.
Soot around your furnace is also an indication of a problem. Soot can build up to in your venting system and block it. If your furnace is vented through a masonry chimney, look for white residue on the brick. This is a sign that mineral salts are coming through the masonry because too much moisture is inside the chimney. Although flame color doesn't always mean the presence of carbon monoxide, a change in the color of your flame, such as blue becoming yellow, indicates that the level of carbon monoxide has increased, and this may be caused by a blocked flue.
A blocked or damaged furnace flue prevents combustion gases from escaping outside. Instead these gases are released into your home. Once inside, they recirculate, and then carbon monoxide becomes part of the air taken in during the combustion process. This increases the amount of carbon monoxide present. The cycle continues and can build up to deadly levels of carbon monoxide in your home.
Symptoms of carbon monoxide poisoning resemble the flu, without fever, in the beginning. If you or your family experience headache, nausea or vomiting, dizziness, fatigue, difficulty breathing or loss of consciousness, go outside your home immediately. If the symptoms lessen or go away but return once inside, you may have carbon monoxide poisoning. Open all doors and windows and turn off any combustion appliances. Seek medical attention. Have your furnace inspected and the flue cleaned immediately by a professional. Have carbon monoxide detectors installed in your home.
Your furnace needs to have its venting system cleaned every year. The buildup of particulates is not as significant as it is with a fireplace flue, but over time, they can reduce the efficiency of the flue. This is dangerous and can lead to carbon monoxide poisoning. Contact a qualified professional to have the venting system cleaned and inspected for damage or leaks even when the furnace appears to operate properly. Only a trained technician can detect blockages or buildup inside your furnace flue and correct the problem. Call Self Heating and Cooling to check your heating system and verify the flue pipe is working as it should.
Lastly - Close the seasonal damper in the summer months.
There is also the option of maintaining your humidifier when you schedule a routine service for your furnace. This will ensure both systems are clean and in working order going into the cooler months. Give Self Heating & Cooling a call today at 678-909-6377 to schedule your HVAC tune-up and ask about adding in humidifier service.
One of the most important aspects of choosing an HVAC system for your home or business is its SEER or Seasonal Energy Efficiency Rating. Prior to 2015, the national minimum SEER rating for a residential HVAC system was 13, regardless of your location. Now, however, the acceptable minimum will depend on your area, and in some cases, the type of system you choose to install.
The SEER rating, determined by the AHRI (Air-Conditioning, Heating, and Refrigeration Institute), is to ensure that HVAC systems are productive, safe, and environmentally friendly. The rating calculates the average cooling output a unit provides versus how much energy it consumes, when it’s run in accordance with the kind of yearly use patterns typical in average homes. The higher the rating, the better energy efficiency the system provides.
While an HVAC unit with a high SEER rating may cost more, you’ll see a decrease in utility bills for your home or business, thanks to the system’s effectiveness in conserving energy efficiency. What’s more, using less energy also decreases your carbon footprint, so you can feel good about your contribution to a healthier environment.
The U.S. is broken down into three regions based on the climate for the states included in each of the regions, which means the SEER ratings can differ from state to state. That’s why it’s important to ensure that your HVAC system meets the new SEER requirements in your area.
If you have an HVAC gas pack instead of a heat pump, it must have a minimum SEER of 14, no matter your location.
When choosing your new HVAC system, don’t assume that bigger means better, since the square footage to be heated and cooled is an important consideration. A unit that is too big for a small area will not work efficiently—in fact, it will over compensate. A system that is too small to keep a larger area comfortable will work overtime, running up the utility bill and putting additional strain on the unit. One of the biggest factors in determining the HVAC efficiency is the thermal rating of your property. This means addressing any necessary improvements that affect the temperature in your home or business. Here’s how you can ensure a better energy efficient output:
To ensure that you’ll see a return on investment for the cost of your new unit, you’ll need to consider how long you plan to stay in your home. For example, if you purchase a more expensive 36,000 BTU unit with a 16 SEER that costs $6,000, you’ll have better efficiency—but it could take up to 9 years before you fully recoup the cost of the initial investment. In this case, a less expensive unit that can accommodate the square footage and a lower SEER rating may be the wiser choice.
Benefits of SEER Ratings
As long as your home is properly insulated, devoid of areas where air can leak in or out, you can expect better efficiency—and therefore, decreased energy bills. Even better, if you purchase an Energy Star certified air conditioners, you’re eligible for federal tax rebates, which helps defray the cost of the equipment. And make sure to check with your local utility company, since they may offer rebates for installing an energy efficient air conditioning and heating system.
While your final choice will depend on a variety of factors, you can get a general feel for the annual energy savings from different systems by performing a simple cost calculation, which will take into account your individual system’s efficiency ratings, the size of your home, and the size of your unit, among other factors.
