Your HVAC Should Be Working For You, Here's How
The HVAC system in any home is vital to maintaining a comfortable environment. Perhaps you are here because you have experienced problems with it in the past, or you just looking for information on how to properly maintain it. Either way, the article below is a great resource on the upkeep of HVAC systems.
Make sure you ask for an estimate in writing before choosing a specific HVAC vendor. There are a lot of moving pieces when it comes to purchasing these big items. You'll want to compare not only the cost of the equipment, but also the set up and the overall energy costs.
One of the most important things to consider when purchasing a new heating and cooling system is the manufacturer's warranty. Units come with a variety of warranties. Choose one with a long warranty for maximum long term savings. Generally, it is advised that homeowners should purchase the extended warranty if one is offered.
Do you hear a clicking sound when your fan is turning? This may mean that there is something in the way of the blades of the fan. If it gets so bad that the blade bends, you must replace it, just unbending it will leave the fan unbalanced and can cause further issues.
Consumers are usually advised to have their HVAC systems inspected twice a year. The normally recommended time for HVAC system inspections is once before the peak cooling season when it gets hot and you'll be using your AC, and once before the peak heating season, during the cold months when you're likely to be using your heat. Check it out just to be safe even if there is nothing broken.
The correct HVAC system should have sealed air ducts to minimize heating or cooling loss as air travels to different rooms. The heating or cooling requirements of different rooms in the home should be taken into consideration. There is no reason to increase energy usage by controlling the temperature in rooms that are used very little.
To save money on your HVAC system, turn the air conditioning down at night and let your home warm up a bit. To keep yourself cool, use a chilling water-filled pillow to cool down your head and your whole body as a result. This combined with a fan will keep you from overheating while saving on your utility bills.
Consider all of your alternatives before installing a central air conditioner. You can only cool certain rooms, use whole-house fans, or even make use of a geothermal system. The more efficient the system you set up, the less you'll spend on utility bills over time as you use it.
Outer coils can be cleaned with a regular outdoor hose before you turn the unit on for the season. That said, interior coils should be taken care of by a professional so that you don't do any damage as you attempt to clean them. Bring someone in to complete a check up.

Make sure you wipe up any water that is close to the air intake of the vents of your HVAC system. Clean up any water that is standing around because water can cause mold to easily expand. Some water buildup is normal but if you're picking up water more than once every six months you might have a problem, so contact a HVAC technician.
To reduce the air conditioning's energy cost, close drapes, blinds and shades that cover windows which face the sun. Also, white shades will reflect the heat away from the house, keeping it cooler and saving you money. It is also recommended that you close the vents in rooms that are not used often. This will ensure that you are not spending money cooling less-used rooms.
If you feel like you are spending too much money on your heating and cooling, there is a simple way to reduce this cost. Raise or lower the temperature depending on the season. A single degree in temperature change can equate to almost a nine percent savings in cooling and heating costs.
Make sure your HVAC is clear when working outside. You should try keeping any vegetation about two feet away from your outdoor units. Keep the areas above it and on each side of it clear. Make sure you aim your grass clippings away from the unit when mowing. Keep leaves from getting inside your unit in the fall.

A great way to reduce the stress on your HVAC unit is to install ceiling fans in your home. During the summer, you can have them blow downward to cool the air and make your home feel more comfortable. In the winter you can reverse the direction and circulate warm air trapped at the ceiling.
If your HVAC unit is not operating as efficiently as it once was, check the evaporator coil in it? There may be some debris blocking it which is causing the issue. You can use a soft brush to clean it - like the one you find as an attachment for handheld vacuum cleaners.
Every season inspect the outdoor condenser unit of your HVAC system. Remove any weeds and leaves that may be obstructing air flow to the unit. Hose off the inside and outside of the unit to remove any dirt build up. Cover the motor with plastic bags prior to rinsing the unit so that you do not get it wet.
Is your home's electrical set-up ready to handle a new air conditioning unit? Most homes have 115-volt circuits in place, but larger air conditioners need 230-volts to be used. Some smaller units may need their own dedicated circuit as well to ensure your home doesn't go dark when you turn them on.
Properly functioning home HVAC means room temperatures indoors in seasons both cold and hot. Improperly functioning home HVAC means variable humidity levels indoors, uncomfortable temperatures and air that is possibly even dirty to breathe. Keep your family comfortable, healthy and happy with the ideas within this article about your home's HVAC.
Can the AC filter in your home, office or local mall protect you from Covid-19?
When New York Governor Andrew Cuomo announced last week that malls in New York could not reopen until they installed high-efficiency particulate air filters capable of trapping the virus that causes Covid-19, Harvard environmental health researcher Joseph Gardner Allen was thrilled.
"I've been writing consistently since early February about how healthy buildings should be the first line of defense against the novel coronavirus," said Allen, who directs the Healthy Buildings program at the Harvard T.H. Chan School of Public Health.
"I'm really grateful that we have a leader in the country -- somewhere -- who was finally talking about healthy buildings, ventilation and filtration," Allen said. "That hasn't happened before. It just hasn't happened."
A push to action
Allen was one of 239 scientists who wrote an open letter to the World Health Organization, the US Centers for Disease Control and Prevention and other health agencies, asking for a change in their guidance to the public on how the novel coronavirus, or SARS-CoV-2, can spread.
Current guidance only focuses on "hand washing, maintaining social distancing, and droplet precautions," according to the letter, published Monday in the journal Clinical Infectious Diseases.
The health agencies are ignoring the tiny droplets of virus that sputter and spray from our mouths, become aerosolized and then float away into the air, the scientists said, as a likely means of transmission.
"They don't want to talk about airborne transmission because that is going to make people afraid," co-author Donald Milton, a professor of environmental health at the University of Maryland, told CNN in a prior interview.
"The best vaccine against fear is knowledge and empowering people to take care of themselves," Milton said. "Why wearing a mask is important is because it blocks the aerosols at their source, when it is easy to block them."
MERV ratings
In his edict to New York mall owners, Cuomo was talking about HEPA filters, which have the highest MERV ratings, between 17 and 20.
What's MERV? It stands for "minimum efficiency reporting value," and it's how filters are rated in their ability to trap tiny particles. The MERV ratings go from one to 20: Filters with higher MERV ratings are more effective than filters with lower ratings.
At the highest end, HEPA filters are used by hospitals to create sterile rooms for surgeries and to control infectious diseases, and are able to remove 99.97% of dust, pollen, mold, bacteria and other airborne particles with a size as small as 0.3 microns. For comparison, Covid-19 is thought to be between 0.06 to 1.4 microns.
"Filters are rated at their worst performance, so 99.97% is the worst it will do," Allen said. "And that's rated for a particle size of 0.3 microns, but smaller and larger it actually does better. So the point is that it's capturing nearly all particles."
Unfortunately, most businesses and home owners may find it difficult to retrofit their existing system to accommodate a HEPA filter, or any filter higher than the rating recommended by the system's manufacturer.
Doing so can actually impair the system's performance: Smaller pores in HEPA air filters make it more difficult for it to push air. Using denser filters can affect the efficiency of the unit and strain the fan, while decreasing indoor air quality -- the opposite of what you desire.
"HEPA filtration is not always going to be feasible or practical," Allen said. "But there are other filters that can do the job. What is recommended now by the standard setting body for HVAC is a MERV 13 filter."
High-efficiency filters in the 13-to-16 MERV range are often used in hospitals, nursing homes, research labs and other places where filtration is important.
