Commercial HVAC

Major winter storms are still months away, but as the weather changes, it’s important to pay attention to your property’s HVAC units, furnaces, and related systems. Inspecting them now will pay off later, when it’s too cold to check it. Pre-season maintenance is also important as it can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of control. Hiring an HVAC company to inspect and do maintenance on your system every fall and spring to keep your systems running efficiently will keep costs down in the long run, especially if it’s a larger commercial building. They’ll do things like inspect and clean the wiring and mechanisms of the unit, which is bit more challenging for the average businessowner.But you can prolong the life and increase the efficiency of your system if you follow this maintenance plan:

Check and replace your air filters often

The most important thing you can do at home is inspect your air filter. Dirty air filters make your HVAC system less efficient and cause undue strain on its working parts. Set a reminder each month to check your air filter and replace it if it is dirty or clogged. We recommend changing your filters every 30 to 90 days, although depending on the environment, they may need to replaced sooner.

Listen for unusual noises

One more passive things you can do is to keep an ear open for odd noises when your system is running. Often times, noises in your system are created by register blockages, debris in the vents, or loose bolts on the furnace or registers. If you hear any odd noises, try to locate the source. If you can’t find the source, check out this list of common HVAC system noises, what they mean and how to fix them. If this does not solve the problem, go to tip seven.

Keep your heating systems free of debris

If you have an outdoor unit, it is important to keep the system free of debris. Check your unit every week or so for leaves, pollen, dirt, sticks or other debris. Clear the debris from the top and sides of the system using gloves and, if necessary, a hose. This allows for maximum airflow to the fan and increases your unit’s efficiency and lifespan. In order to ensure the cleanest system possible, try to remove anything that blocks air flow to the system, leaving about two feet of space around the unit.

Use fans to give your system a break

Another passive way to keep your system healthy is to use fans when possible to give your system a break. On hot summer days, use ceiling fans and portable fans to circulate air through the house and help your HVAC system bring the temperature in your home down quicker. On cooler days, instead of programming your thermostat, open your windows and turn on your fans to circulate the cool air into the house and keep temperatures comfortable. Giving your system a break when you can will lengthen the life of equipment and save you money on your energy bills.

indoor air qualityIndoor Air Quality is an extremely important aspect of being a homeowner. A not so fun fact; the quality of the air inside the four walls of your home is often worse than the polluted outdoor air itself. The potential sources of air pollution are lurking in nearly every room in your home and possibly interfering with the health of you and your loved ones.

Keeping Pollutants Out: First and foremost, do not allow smoking inside of your home. If you haven’t already, installing a carbon monoxide detector outside the bedrooms is a very effective way to protect you and your family from the invisible and odorless gas that leads to carbon monoxide poisoning. If you do have fuel-burning appliances, you should have a qualified technician inspect the devices at least once a year. Testing for radon and avoiding paints and household cleaners with high levels of chemicals are also best practices for keeping a safe air quality level in your home.

However, when it comes to household irritants such as dust, dander and mold, protocol is different. With proper education and care, keeping out these common allergens is simple to do. Follow these methods of keeping your air as clean as possible.

Ventilate: One of the main reasons that indoor pollution is often so much worse than outdoor air is because the contaminants in the building have nowhere to go. Once they are inside, they become trapped and continuously circulate through the air. Flowing fresh air is important, but also be wary of common outdoor pollutants, especially when pollen counts are high. Keeping thick screens in your windows – that can let cool air in but keep outdoor pollutants out – is key for circulating fresh air. It lets new, clean air in while keeping unclean air out. Fans are also great sources of circulating fresh air. Window fans especially, offer versatile air flow. rdhvac air ventilation

Clean: Regular dusting, vacuuming and overall cleanliness of your home are the best ways to keep dust and dander at bay. If you have pets, be sure to bathe them regularly to reduce the amount of dander released into the air. Combing or brushing is another way to remove excess hair and dead skin cells, but make sure to do this outside so that you aren’t bringing new irritants indoors. rdhvac cleaning

Purify: In addition to regular ventilating, dehumidifying and cleaning, the best way to ensure that your air is pure and clean is with an air purifier. An air purifier such as the Start breathing better and purify your air today. rdhvac purify


Mold Remediation | Indoor Air Quality Kennett Square, PAThe majority of modern humans spend an inordinate amount of time indoors, making indoor air quality of the highest importance. Live organisms typically take the form of Mold & Bacteria. As such, we should all be concerned with what is in the air we are breathing. Children and the elderly are especially susceptible to adverse reactions to pollutants in the air. Contact with these substances can cause sore eyes, burning in the nose/throat and headaches, as well as more severe effects such as respiratory illness, heart disease, cancer or other long term conditions.

How Did I Get Mold In My Home?

Molds are part of the natural environment and can begin reproducing quite easily. All it takes is for some spores to land on a wet surface and it will begin replicating. Mold can enter through many different passages such as your doorways, vents, windows and central air systems. Mold can even be tracked in from outside when it attaches itself to clothing, bags, or even pets. The mold tends to grow and thrive in places with an abundance of moisture such as leaky roofs and windows, or where there may have been some flooding.

How Serious Of A Problem Is The Mold Potentially?

Some mold is totally harmless – like *cosmetic* black mold or Ophistomoid fungi. These harmless black molds are often found on framing lumber and sometimes plywood. However, Stachybotrys Atra is a toxic mold and notorious mycotoxin producer. Some symptoms of exposure to toxic black mold include dermatitis, sinusitis, conjunctivitis. Aggravation of asthma and there has been evidence linking it with pulmonary hemosiderosis which causes bleeding in the lungs of infants less than 6 months old. This mold tends to grow on soaked wood, wall panels, cotton, cardboard and stacks of newspapers. Aspergillus is another mold that is very harmful, known to cause disease in humans and animals. Aspergillus is commonly found in house dust or areas of water damage / extreme dampness. Whether you have mold that is relatively harmless or a serious health concern, it all does one thing which is lead to more mold breeding so your situation can always get worse. It’s best to handle any signs of mold as soon as you uncover them.

What To Do When Mold Is Uncovered

The key to mold control is having control over moisture and humidity levels within your home. There’s no practical way to eliminate all mold spores, so the way to control it is to control moisture. Upon finding a mold issue, you must immediately eliminate the source of moisture. If there’s a leak or flooding, the first step is to resolve those issues. Next, reduce indoor humidity so that it rests at a level between 30-60%. Ways you can reduce the humidity are venting bathrooms, using air conditioning systems / de-humidifiers, and using exhaust fans whenever cooking, dishwashing, and cleaning.
