Specialty HVAC Applications


The traditional HVAC system is ideal for homes, in addition to most businesses.

However, there are a number of specialized establishments that require unique equipment and air conditions in order to function properly. This means that some companies will be equipped with a unique HVAC system to ensure proper ventilation, as well proper air quality, for their space.

Some examples of areas that would require specialized HVAC systems include:

  • Operating Rooms
  • Cigar Lounges
  • Server Rooms

When installing specialized HVAC systems, it’s essential that you find a licensed technician who, in addition to being certified, also understands the specialized conditions you need to maintain.

It’s also important that, in addition to finding a technician who understands your specialized HVAC system, you find someone able to maintain it. Compromised air quality may not seem like a big deal, but if dust and debris were allowed in an operating room through an improperly maintained ventilation system the results could be fatal. Maintaining proper air quality is essential.

If you’re looking for a specialist to install a specialized HVAC system for your establishment, or need a technician to repair the one you already have, then give the experts at DC Cheek Heating and Cooling a call at (770)882-2435.

The Three Types of Air Filters That Keep Our Homes Clean


When it comes to air filters, we’re looking at three basic types: mechanical, ion generators and electronic air cleaners. In addition to these, there are hybrid systems that combine mechanical, ion and/or electronic features. All of them work to keep the air in your home clean, and achieve this goal in different ways.

Mechanical Filters

Mechanical filters are the models found in most homes with central heating and/or air conditioning. The standard mechanical filter is a flat pane that contains coarse fibers (typically fiberglass, aluminum or synthetic material) held in place with a cardboard or plastic frame. Generally, mechanical filters are efficient at collecting large particles, but only remove a small percentage of smaller particles. When it comes to mechanical filters, the more dense the filter material or the greater the filter surface area, the better it will remove pollutants. These types of filters may be affordable but they are also the least effective, stopping only 10% to 40% of pollutants.

Ion Generators (or Air Ionizers)

Ion generators are portable devices that use electrostatic charges to remove particles such as allergens, pollen, mold spores, dust and animal dander from indoor air. All of the previously mentioned particles are neutral, meaning they have no charge and can float freely in the air. The ion generator charges the neutral particles and causes them to stick to each other to form clumps. These clumps of particles then become heavy enough so that gravity can pull them down to the floor, where they can be vacuumed up, rather than staying in suspension where they can be breathed in and cause allergic reactions. Most ion systems require either filter replacement or periodic cleaning. They are also highly efficient and can remove 25% to 94% of the pollutants.

Electronic Air Cleaners

Electronic air cleaners use an electrical field like a powerful magnet to trap charged particles. Whole-house air cleaners are most often installed in house ducts between the cold air return and the fan, but they can also be in portable units with fans. Electronic air cleaners are the most efficient cleaners of indoor air, removing up to 95% of dirt, dust and smoke.

Troubleshooting Air Heat Pumps


Heat pumps require regular maintenance to ensure proper operation and extend the life of the unit. The most common cause of problems occurring in a heat pump is due to a lack of water flow. The inhibition of water flow can be the result of various things going wrong, here are a few possible reasons:

  • There is a blocked filter in the heating circuit.
  • There is a water valve in the fluid circuit which has been shut off.
  • A pump failure has occurred.
  • The strainer of the heat pump is blocked. This can often happen if the installer has not properly cleaned the system. Rest assured that our technicians are well trained in the installation and maintenance of heat pumps. If your strainer is clogged, our technician will undo the strainer and take out the filter element. They will then proceed to wash it in clean water and replace it.
  • Blockage in the brine (or antifreeze) circuit. If this is the case, our professionals will check your heat pumps filters, the status of the antifreeze to determine whether it has aged or if there is a failed pump.

Most problems involving heat pump system performance require specialist intervention. A qualified service provider should annually inspect your home heat pump in order to ensure proper operation. Contact DC Cheek Heating & Cooling today to schedule an evaluation visit. Our technicians will examine and determine the status of your home’s heat pump system. 770-888-8788.


Time to Have Your Home Air Ducts Cleaned?


Having your home’s air ducts cleaned will increase furnace efficiency, reduce dust in the air and help allergy sufferers. To help you decide whether this service is for you – here are key questions to ask yourself.

  • How old is your furnace? Have you ever had the ducts cleaned before? You get the most benefit from air duct cleaning the first time it is done because that’s when years of dust (which could decrease fuel efficiency by as much as 10 per cent) and any large objects blocking the air ducts are removed.
  • Do you have cold spots in your house? This could be caused by large objects blocking the ducts and preventing heat from reaching individual rooms.
  • Do you notice an abnormal amount of dust in the house? The dust could be coming from the blocked air ducts.
  • Are you bothered by allergies and dust in the air? Cleaning air ducts automatically relieves allergies and reduces the amount of dust and allergens circulating in the home.
  • Do you have central air conditioning? The coil on air conditioners becomes inefficient when choked with dust and having your ducts cleaned helps keep it clean.

Contact DC Cheek Heating & Cooling today to schedule an evaluation visit. Our technicians will examine and determine the status of your home’s air duct system. Depending on the results we find, we will then recommend the best possible solution to improve the air quality and comfort of your home. 770-888-8788.



How to Reduce a Home’s Heating Bills


Are you looking to save money and to reduce your monthly energy bills? There are many ways to slash your energy bills without necessarily having to sacrifice the comfort of your family. You can implement the following energy-saving methods:

  • Install a programmable thermostat. Whenever possible, lower the thermostat. A programmable thermostat is the best option, is the most efficient and can be easily installed. Lowering the temperature by a few degrees when sleeping and by several additional degrees when you are away from home is recommended.
  • Follow a maintenance program. Your HVAC system should be serviced annually by a qualified DC Cheeks professional.
  • De-clutter your home. Ensure air registers, heating ducts, and radiators are clean and not blocked with furniture or clutter.
  • Replace worn out weather stripping. Weatherize exterior windows and doors to prevent cold air from seeping into your home.
  • Pay more attention. Turn off lights, electronic devices, exhaust fans, and appliances when not in use.
  • Upgrade outdated HVAC equipment. Replace outdated furnaces, water heaters, or other appliances. Ensure replacement items you purchase are Energy Star certified.
  • Install or upgrade your home’s insulation system. There should be a good insulation system in the attic, walls, floors, basement, and crawl spaces of your home.

How to Choose a Gas Water Heater that Best Suits Your Home


Except for heating and cooling your house, water heating is typically a home’s greatest consumer of energy. The newer water heater models are significantly more efficient than older models – even ones that are a few years old. Installing a new water heater will cut your utility bills and should provide more hot water for your home.


If you’re choosing to go with a gas water heater, your first consideration should be the first-hour rating, or FHR. This rate indicates how much hot water the water heater can produce in one hour. This includes the volume of hot water in the tank after not being used all night and the amount of new hot water the burners can heat in one hour.


The efficiency of gas or electric water heaters can be compared by looking at their energy factor, or EF. This energy factor is a number between 0 and 1; it relates to how much of each energy dollar results in heated water from the water heater tank. A higher EF indicates higher efficiency and lower utility bills.


Another important feature to consider in a gas water heater is its tank insulation. Two inches of foam insulation are often used in the most efficient models. Most heaters will also have special baffles in the internal flue pipe to improve the heat transfer to the water. For simplicity, the EF already takes these factors into account. Finally, the length of the warranty on the gas heater you choose at the end of the day is also an important factor.

It’s Time to Tune Up Your Heating System


Heating systems need to be tuned up periodically to keep them operating smoothly and efficiently. If you haven’t done so already, now is the time to get your heating system inspected, cleaned and tuned-up. Some of this annual maintenance can be done by homeowners, but most of it should be done by a heating system technician.

Here’s list of some common heating tune-ups:

– Replace air filters regularly. If you have a forced-air distribution system with a furnace or heat pump, replace the primary air filter at the start of the heating season and then every month or two throughout the season, depending on how heavily the system operates. Clean filters will prolong the lifetime of your system and help it operate efficiently.
– Check and adjust your thermostats. If you have programmable thermostats in your house, take advantage of their convenience and savings potential by properly setting them.
– Inspect and clean air vents and baseboard radiators. Efficient heating depends on warm air rising into your rooms from hot-air vents or baseboard radiators. Make sure these aren’t blocked by carpets or furniture, and vacuum them at the start of the heating season to improve heat transfer.

Prepare Your Home for Winter with a Gas Furnace Inspection


As the weather begins to cool down in November, DC Cheek would like to remind our clients to schedule a gas furnace inspection. Safety and efficiency inspections performed on gas furnaces will help customers save money on their home heating bills this winter.


To avoid gas furnace problems during the winter, DC Cheek has created the following safety and efficiency guideline for your reference. Performing the tasks on this list before turning on the furnace this year can save you money on energy costs, and ensures that your gas heating appliances are in safe working condition. Some of these steps can be performed by you, while others, for safety reasons, should only be performed by a licensed technician.


DC Cheek Furnace Safety and Efficiency Inspection Checklist:


  • Look for cracked, rusted, misaligned, or clogged vents.
  • Check your flue assembly for alignment and rigidity; a small earthquake is all it takes to loosen the flue and allow the products of combustion to seep into your home.
  • Make sure the flame is blue. A yellow flame may be a sign that the burner could be out of adjustment.
  • Inspect for soot in the burning area and vents. This can be an indication that the gas burner is not properly adjusted and requires servicing.
  • Look for cracked or frayed blower belts.
  • Clean all dust and lint near the burning chamber. Please ensure that the thermostat is in the off position prior to cleaning.
  • Clean or replace your furnace filter and make sure the blower door is properly secured.
  • Do not store or use combustible materials or liquids near any gas appliance.
  • Check ducts for leaks and have them properly insulated.

Improving Indoor Quality with Duct Cleaning


Should you have your ducts cleaned by a professional service? There are three times when the answer is an unequivocal “yes.” You should have your ducts cleaned when there is substantial visible mold growth inside the ducts, when ducts are infested with vermin, or when ducts are clogged with so much dust and debris that particles large enough to see are blowing into your home.

What the duct cleaning service includes:

– Opening the access ports to allow the whole duct system to be cleaned and inspected.
– Checking for asbestos containing materials before cleaning the system.
– Using vacuum equipment that exhausts particles outside of the home or use only high-efficiency particle air (HEPA) vacuuming equipment.
– Using well-controlled brushing of duct surfaces in conjunction with contact vacuum cleaning to dislodge dirt or other particles.
– Using soft-bristled brushes for fibreglass duct board and sheet metal ducts lined with fibreglass.
– Taking care to protect the duct work, including sealing and re-insulating any access holes the service provider may have made or used to ensure they’re airtight.

We take around 20,000 breaths a day and more than 10,000 of them occur indoors. Although outdoor air pollution is an obvious problem, indoor air routinely tests as worse. This reiterates the point that we should take absolute care in maintaining our duct systems in order to assure that the air circulating in our home is as clean as possible.

HVAC Maintenance Guarantees Air Quality of Your Home


One of the most important factors affecting indoor air quality is how a building is heated, ventilated and air conditioned. Well designed and maintained ventilation and air-conditioning systems are crucial to having good air quality, but problems can form quickly when the HVAC system is not functioning correctly.
Lack of HVAC maintenance can quickly lead to problems. Sometimes a home will be having indoor air quality problems because controls in the control system have failed and no one has noticed. Problems such as clogged up filters and unemptied drain pans for air conditioners and dehumidifiers can cut down air circulation while providing a fertile breeding ground for mold and bacteria which have been associated with respiratory allergies and asthma and have been linked to the airborne transmission of various infections.
A microbiological growth may also occur in an HVAC system equipped with low efficiency filters, humidifiers that use water recycling or in areas in which water condensation remains stagnant and large re-circulation of air is present. Microorganisms can thus spread in the indoor air by the HVAC system and be inhaled.
