Know These HVAC Airflow Problems

Know These HVAC Airflow ProblemsAirflow problems with your HVAC system can leave you dealing with discomforting issues like hot or cold spots, uneven temperatures in different rooms, and/or a drop in conditioned air output from the registers. What starts out as a gradual loss of comfort can escalate into a costly equipment breakdown or failure, so it’s vital to have the problem addressed. Here’s a look at some of the most common causes or airflow issues and what to do about them:

Obstructed Registers and Duct Openings

If you’ve closed some registers, or your return ducts are covered by furniture, drapes, throw rugs, toys or other items, it can cause temperature inconsistencies in different areas of your home and a damaging imbalance in system airflow. You can fix this by wiping down each vent cover and vacuuming out the duct openings, and then checking that your louvered registers are completely open and all supply and return vents are free from obstructions.

Clogged Air Filter

If you’ve neglected to change your system’s air filter and it’s become clogged by dust and debris, you’ll notice a drop in airflow at the registers. Restricted airflow can also increase your HVAC equipment’s workload and energy consumption, or even ruin a component. Checking the filter monthly and replacing it whenever it looks dirty is the best way to prevent such problems.

Ductwork Flaws

A ductwork system that’s poorly designed, damaged, or leaking can hinder proper airflow through your HVAC system. A trained HVAC technician should inspect your ductwork to determine the cause and the right remedy, which may involve repairing, sealing and insulating or replacing the ductwork.

Oversized Equipment

If your existing HVAC system wasn’t sized properly, it may be too large to effectively heat or cool your home. HVAC components with too much capacity will short cycle, resulting in a decline in airflow from the registers every time they cycle off. To solve this, a knowledgeable HVAC professional will need to complete a detailed load calculation and install correctly-sized new equipment.

Winter Concerns for Indoor Air Quality

Winter Concerns for Indoor Air QualityThe air in the average home is typically far more polluted than the air outside. And in winter, things are particularly bad. Poor IAQ can exacerbate allergies and asthma, facilitate illnesses like cold and flu, and more. Here are some reasons why your air quality goes down in winter, and a few things you can do about it.

Problems With Your Winter Air

Your winter indoor air quality suffers for a number of reasons. The first is a lack of ventilation. In winter, your house is sealed up tight, to keep warm air in and cold air out. If outside air can’t come in, the same contaminants keep getting cycled through your HVAC system again and again, increasing as the season progresses.

There are other factors affecting your IAQ as well. If you have a gas-burning furnace, you have carbon monoxide fumes to add to the pollution. And finally, there’s the issue of humidity. The air typically gets dryer in winter. And running your furnace dehumidifies it even further. When the humidity level gets below about 30 percent, it fosters viruses and other contaminants.

Improving Your Winter Indoor Air Quality

Here are a few steps you can take to raise your IAQ.

  • Vacuum and dust regularly. With regular cleaning, you can eliminate dust and other contaminants from your air.
  • Get a whole-house humidifier. This counteracts the dehumidifying effect of your HVAC system and allows you to keep your humidity at a healthy level – between 30 and 50 percent.
  • Change your filters. Putting a new air filter in your HVAC system helps ensure it eliminates contaminants effectively. Change your filter every month in winter to maintain its efficiency.
  • Get indoor plants. We all know plants convert carbon dioxide to oxygen. But did you know that some can filter other contaminants out of your air as well? A peace lily or a florist’s chrysanthemum can eliminate formaldehyde, benzene, and even the ammonia that comes from cleaning fluids.

Winter Weather Protection for Your HVAC Unit

Winter Weather Protection for Your HVAC UnitAlthough you don’t generally need your outdoor air conditioner compressor/condenser during the winter, you may have wondered if you should be doing something to protect it from the elements when it’s not in use. The best answer is, for the most part, no — particularly in our mild climate.

 

However, do read on for a few tips on winter weather protection in case inclement weather occurs.

 

Weather in Peachtree City

 

We seldom see snow or ice in Peachtree City, but it can happen. Temperatures can fall into the 20s or even lower during the rare ice storm. Will that necessitate taking measures to protect your compressor? Not really. These outdoor units are designed to be tough. The only issue your compressor might have is if it’s directly in the path of a melting/freezing ice dam on the edge of the roof. If water is melting in the day and refreezing overnight as it drips inside the unit, it could be damaged. If you are concerned, tie down a piece of plywood over the unit so that melt water doesn’t drip inside. This could also protect it from large hail during a thunderstorm.

 

It can rain frequently during the winter in Peachtree City, but that’s not generally a problem for your compressor unless where it sits tends to flood. Then, you will probably need to look into raising or moving the unit.

 

In the event of high winds this winter, make sure that all yard furniture, tools or other objects are secured so that they are not propelled into the unit during a storm.

 

Keeping Debris Out of the Unit

 

Once the grass stops growing this winter, you won’t have any further concerns about grass cuttings flying into the coils. But you might keep an eye on any weeds, falling leaves or other debris piling up around the compressor, and make sure the area stays clear.

 

It’s usually best not to cover up the unit with a tarp, as this can encourage rodents to hole up in it.

HVAC Control Systems: What Are They?

HVAC Control Systems: What Are They?The words “HVAC control system” typically bring to mind the complex climate control systems that manage heating, ventilation and air conditioning in industrial or commercial buildings. These elaborate systems ensure energy efficiency and occupant comfort using software-managed sensors and controllers that continually monitor the building’s interior conditions and operate the various HVAC components.

HVAC Controls Used in Homes

In a home with central HVAC, the thermostat is what controls the air conditioner, furnace and the blower unit that delivers conditioned air. Early thermostats were basic mechanical devices that signaled the equipment to start and stop at specific temperature set points. Technology has advanced in recent years, and today, there are sophisticated home HVAC controls available that provide greater energy efficiency, comfort and convenience, including:

  • Programmable digital thermostats. Digital thermostats use a thermistor to measure room temperature, and a microcontroller to convert that measurement to a digital temperature reading. Factory-installed software in programmable models allows a homeowner to input their temperature preferences for up to eight setback periods per day to maintain comfort while saving energy.
  • Zoning systems. Zoning divides a home into two or more areas to provide more precise control of comfort and energy consumption. A typical zoning system consists of a centrally-located control panel that’s linked to ductwork dampers that define the zones, and a programmable thermostat in each zone. The homeowner can schedule setbacks and their desired heating and cooling parameters for each zone via the control panel.
  • Learning thermostats. These “communicating” thermostats are programmable, plus they gather and send data on conditions in a home, allowing the owner to monitor and change the settings remotely. The most advanced models use software algorithms that let the device “learn” the homeowner’s comfort preferences and make adjustments automatically. The latest versions can monitor and make adjustments related to the outdoor weather, indoor air quality, humidity levels and the home’s occupancy, and send alerts if problems arise with the HVAC equipment, or the system needs routine maintenance.

How to Use a Backup Generator Safely

A generator can be a lifesaver during a power outage, but only if you practice each aspect of generator safety. These appliances use combustible fuels to produce electricity. Generators have the capacity to do a lot of good, but when misused, can cause serious harm.

Always use the generator outdoors.

Generators use gas or diesel, both of which create carbon monoxide. Using one indoors will create high amounts of CO in a short period. If you are using the generator near a window or door be sure to keep them closed at all times.

You may smell the fumes from the generator, but the CO created has no odor, color, or taste. CO can easily overcome you and your family. If you need to run the generator for extended periods of time, place a CO detector in the room closest to its location outdoors.

Watch where you connect

Never plug the generator into an electrical outlet inside your home to backfeed the powers supply. Ignoring this generator safety mandate could cause a serious or fatal shock to a neighbor or utility worker who is working on the line.

Extension Cords

Use heavy-duty extension cords to supply power to your appliances or fixtures. Running a cord that’s too light can cause an electrical fire.

 

Keep extra gasoline or diesel in an ANSI-approved gas can.

These cans are bright red and vented. Put the can in a place where your children or pets won’t be able to access it. Never store gasoline in the house.

Do not operate the generator in the rain.

If you must run it, try to put it under an eave or table to keep it dry. Manufacturers do make tents to use during hurricanes that keep the generators dry and the carbon monoxide safely away from the house.

Let the generator cool down before you add more fuel.

They get very hot and spilling gas on them could start a fire.
