The Truth About Mold

There’s Good Mold and There’s Bad Mold

Molds are the “bleu” in bleu cheese and Roquefort. Molds improve our wine. They produce penicillin and antibiotics and are used widely in the food and beverage industry. Without mold and mold’s decaying mechanism, the natural environment would be overwhelmed with large amounts of dead organic matter.

Despite many harmless and beneficial molds, some molds can be toxic and pose health threats to humans. The Environmental Protection Agency (EPA) cautions that all molds can cause health problems under the right conditions. The word “toxic” refers to mold that produces hazardous compounds, or mycotoxins.

Often included in the list of toxic molds is Stachybotrys Chartarum, a greenish-black mold, which can grow on high-cellulose, low-nitrogen materials such as fiberboard, drywall, paper, dust, and lint – all of which are found in homes – when these materials become wet.

There is evidence that mold exposure can cause the following symptoms:

Allergic reactions, including irritation of the eyes, nose, or throat.
Flu-like symptoms, including fatigue, dizziness, headaches, and diarrhea.
Worsening of asthma.

How to Minimize Mold Growth
Mold is a natural byproduct of the fungi family that thrives when organic substances and water combine under certain circumstances. Mold reproduces via spores that can remain dormant, yet viable, for years. They “come alive” again in the presence of moisture.

HVACR mechanical systems are not generators of mold; their metallic surfaces do not provide the organic matter mold needs to grow. However, systems that are not well maintained could support mold growth. It’s important that your system:

Is designed and installed correctly.
Is properly and regularly maintained.
Controls the moisture in your building.
Uses good filtration methods to keep your air clean.

Preventing Mold

Consider augmenting your air conditioner with a dehumidifier. These systems pull the moisture from the […]

How Preventive Maintenance Will Save You Money

Preventive Maintenance = $avings!
Take care of your HVAC system, and it will take care of you.

Preventive maintenance agreements (PMAs) are agreements between you and your Air Conditioning Contractors of America (ACCA) quality contractor for scheduled inspections and maintenance of your heating, ventilation, and air conditioning (HVAC) system.

PMAs are generally scheduled for the spring and fall to maintain peak efficiency, help keep utility bills lower, extend the life of your HVAC system, and avert failures. Sometimes PMAs are referred to as “planned maintenance agreements,” “start and checks,” or “preventive service agreements.” Most agreements offered by ACCA contractors cover an inspection of the entire HVAC system and routine maintenance (such as replacing or cleaning filters).

Energy Consumption
The HVAC system is most likely the single biggest use of energy in your home. In commercial applications where refrigeration is applied (combined with the HVAC systems), huge amounts of energy are used in the building. In fact, over a third of the energy used in the United States is used to heat and cool buildings.

According to the Consortium for Energy Efficiency (CEE), up to 50% more energy can be saved with proper installation, sizing, and maintenance of commercial central air conditioning and heat pumps. Although the CEE study did not measure residential systems, a compelling case can be made that proper maintenance can save homeowners up to 50% as well.

Out of Sight, NOT Out of Mind
The cliché “out of sight, out of mind” is often the reason for neglected maintenance on your HVAC system. HVAC systems are usually installed where they aren’t seen, such as in a section of the basement, a closet, on rooftops, or in mechanical rooms, making them easy to ignore. The systems are simply taken for […]

The average home is up to five times more polluted than the air outside

According to the EPA, the air inside the average home is up to five times more polluted than the air outside. Pollen, dust mites, dirt, and mold spores in your home’s air can cause minor health problems like eye and nose irritation, dizziness, and headaches. Indoor air pollution can also cause more serious problems like respiratory illness, as well as aggravate allergies and asthma. There are three ways you can improve the air quality in your home:

Source Control
You can eliminate many pollutants like dust and pet dander by careful household cleaning. Making sure your heating and air conditioning systems are well-maintained also helps remove pollutants before they reach your home, and cleaning air duct systems may be helpful in keeping your systems maintained.

Improved Ventilation
You can decrease the concentration of indoor pollutants by increasing the quantity of air circulating. Open windows and doors, and use window or attic fans. Bathroom and kitchen exhaust fans move indoor pollutants out of the room, and increase the outdoor ventilation rate at the same time.

Air Cleaners
Well-maintained and efficient air cleaners can significantly lower the amount of pollutants in the air. Their usefulness varies considerably, depending on the type of cleaner (table-top models will probably be less effective than a whole-house system), and on the strength of the indoor pollution source.

Replacing Filters

Replace your heating and cooling air filters regularly when they’re in use. Operating your system with old, dirty filters means energy is wasted and your system may even be damaged. While you’re at it, check and clean the filters in your home’s air cleaners and humidifiers.

Maintenance Scheduling

Schedule a maintenance service call before the heating season starts. If there are any problems with your system, it’s better to find out before it’s freezing outside! Do the same for your cooling system before the sweltering season begins.

Their workmen are courteous, diligent and took care to clean up

We have had GRC Mechanical System at our house for both replacement of older systems and maintenance of our existing systems.  Their work is the best quality.  The installation of new systems was done quickly and professionally.  Their workmen are courteous, diligent and took care to clean up each day before they went home.

We highly recommend GRC for both maintenance and upgrades of residential heating/air conditioning system.

Punctual, knowledgeable, patient, and very personable

GRC Mechanical installed a 4 ton 2 stage Carrier® Infinity air conditioner, a 2 stage Carrier Infinity furnace, an Infinity thermostat, and reinstalled my Aprilair humidifier. (They also removed and carted away my old air conditioner and furnace.)

The salesman for the company, John Russenberger, was very punctual, very knowledgeable, very patient, and very personable. He offered me several different systems in several different price ranges. The work commenced within a week of signing the contract. The job took three days. Terence and Leo were the installers. I was especially impressed by Terence’s expertise. Most of the ductwork had to be made from scratch. Terence constructed it perfectly. He was also very patient in answering all of my questions. In addition, after completing the job and checking the system, Terence and Leo left. To show how conscientious Terence was, he returned because he was not sure he had checked something (he had). I would not hesitate to recommend GRC to any of my friends.

I highly recommend GRC Mechanical

Before replacing my 25 year old Central Air Conditioner, they serviced the old unit for a few years, always promptly coming out on a service call and getting it working again whenever it quit functioning.

Finally when my old unit quit working again and would no longer function, GRC measured the interior space of the home to determine the proper size A/C needed and suggested what would best suit our needs.  They explained the advantages of various new A/C systems at different price points.  We decided on a system and GRC then promptly scheduled installation and professionally installed the new system the following week.

Whether servicing an older A/C system or purchasing a new one, I recommend GRC Mechanical.  They have the training, skill and knowledge to do the job right.
