Your air conditioner is like any other kind of mechanical equipment – it makes some noise when it’s running. You’re no doubt used to the sounds it normally makes, so you notice any unusual, extremely loud or alarming new noises.
Some sounds – like hissing, loud banging or shrill shrieking or squealing – should be checked out by an experienced HVAC professional because they can indicate serious problems that need prompt attention.
Quieting the A/C when it starts making annoying but not serious sounds is fairly easy if you follow these tips:
Clean & Tighten a Noisy Blower Fan
If you’re hearing murmuring or rattling sounds from the air handler cabinet, the fan may be loose or dirty or have a bent blade. You can lessen the noise by wiping any debris from the blades and tightening the center hub with a screwdriver or Allen wrench if the fan is a bit loose and vibrating. If there’s a bent blade, use your hands to gently straighten it.
Lubricate a Loud Fan Motor
Your HVAC system air filter is responsible for trapping dirt, dust, pet dander, hair, pollen and other airborne particles so they don’t accumulate on sensitive system components. Given the filter’s important role, it’s vital to use the most efficient type available for your system and keep it clean.
If you’ve always used disposable filters but you’ve heard about washable air filters and you’re wondering if you should switch, here’s a look at how the two compare in some key areas.
Washable and disposable mechanical filters have different minimum efficiency reporting value (MERV) ratings, which tells you their filtering capabilities:
Washable HVAC air filters typically have MERV ratings from 1-4, so they’re only effective at capturing particles 10 microns and larger, which can include hair, lint, pollen and dust mites. Basic, throw-away flat-panel fiberglass filters have the same low 1-4 MERV ratings. Disposable pleated media filters offer MERV ratings from 5-13, so they can trap particles as small as one micron, such as mold spores, dust mite droppings and pet dander. Maintenance Requirements
If you consider why you should use your bathroom exhaust fans, odor control would probably come to mind first. Having fully-functional exhaust fans, that are sized correctly and installed properly, is important for a number of other reasons too, such as:
Preventing mold growth and structural deterioration. In our Georgia climate, removing excess humidity from the bathrooms helps keep mold growth in check and prevents damage to your drywall, paint, wood and structural components. Preserving cooling efficiency. Getting rid of airborne moisture also helps the A/C operate efficiently so your cooling costs don’t increase. Removing hazardous cleaning chemicals. With good bathroom ventilation, the leftover chemicals from commonly-used bathroom cleaners are less likely to degrade your indoor air quality. Tips for Using Your Bathroom Fans Effectively
Here are some helpful tips on how to make sure your bathroom fans are working as effectively as possible.
Have the right capacity. You can have one or multiple fans in a single bathroom as long as they move sufficient cubic feet per minute (CFM) of air. Average-size bathrooms need one CFM of air movement for each square foot of space. Bathrooms over 100 square feet in size need 50 CFM more for each …
If your aging furnace didn’t keep your home comfortably warm last winter, it’s a good time to seriously consider replacing it. Why replace a furnace now rather than waiting until later in the year? Because upgrading your heating system in the spring offers some big benefits.
Slow Down Discounts
Spring is a typically a slow time of year for HVAC contractors because it’s in between the hectic heating and cooling seasons. HVAC companies want their installers and technicians to stay busy, though, so many offer significant discounts to homeowners who buy new equipment now. Scheduling a spring furnace replacement not only lets you save on equipment cost, but it also gives you more scheduling flexibility because your contractor isn’t booked up.
Our spring weather in Georgia is quite mild, so there’s little risk that you’ll be inconvenienced by a lack of heat while your new furnace is being installed. If your air conditioner is near retirement age, it’s also the ideal time to talk with your HVAC contractor about a package deal. By replacing your furnace and A/C at the same time, you can benefit from optimal comfort and energy savings both summer and winter.
Finding the right furnace for your home can be a tricky endeavor, especially with so many options available. Among these choices are single and two-stage furnaces, both which offer their own sets of advantages and disadvantages. The following takes a look at how both furnaces stack up against one another.
To understand the difference between a single-stage furnace and its two-stage counterpart, it’s important to understand the term “single-stage.” It simply means that the furnace is only capable of generating and dispersing heat at a set speed. Either the unit runs at full throttle or it simply doesn’t run at all.
The relative simplicity of a single-stage furnace makes it slightly easier to maintain and a bit more affordable to purchase. However, operating a single-stage furnace throughout the winter could prove costly, especially since the unit has to cycle on and off constantly to maintain a steady temperature and prevent cold spots from forming in portions of your home.
Just as the name implies, a two-stage furnace is capable of alternating between two states during its operation – a first stage where it runs at roughly half of its capacity and a second stage where …
