Summer Checkups

The Summer heat has your Air Conditioning unit running constantly. In the middle of summer, it is important to make sure that your unit is running well. With the high amount of use this season, it is vital that you replace the filter in your Air conditioner. Replacing the filter allows the airflow in your home to become cleaner. A clean filter will trap more pollen, dust, dander, and other air particulates that can cause respiratory issues, especially in young children. A dirty filter prevents air from flowing as quickly, which can cause you to use more electricity before your home becomes cool. It is also a good idea to vacuum the return vent in your central air system to remove excess dust and debris before it enters the system.
The Summer is an excellent time to have your heater inspected, too. It is important to have a HVAC professional inspect your heating unit before the weather gets cold. Any repairs that your heater might need can be taken care of before the fall if the issue is found now.

Professional Tune-Ups and Maintenance During the Off-Season

The harsh winter is dying out, which will eventually lead to a harsh summer. In the spring, your heating and air conditioning systems get a rest from constant use. This is the perfect time to get your systems tuned-up and maintained by our licensed professionals. Tune-ups make sure that your system is up and running for when you need them, and it is best to have them done when you are not relying on them to keep your home comfortable. Before making the switch from the heater to the A/C, have both checked and get a tune-up from our professional service staff. Keep your home, and your family comfortable all year long with properly working and maintenanced heaters and air conditioners.

Winter Air Conditioning Maintenance

Your Air Conditioner may not see use in the cold winter, but you should make sure it is up and running. Air Conditioners should be checked and maintenanced during the winter while you and your family are not relying on it to keep your home cool. While the heat runs strong in your home, the proper care and maintenance on your air conditioner can keep you home cool in the summer without issues.
Filters in an A/C unit should be cleaned or replaced regularly, to keep it running efficiently. A dirty filter can make your air conditioner use up more energy than necessary. The evaporator coil and condenser coils in an A/C can become dirty over time, even with clean filters. Dirty coils can become insulated, which prevents them from absorbing heat and producing cold air. Covering your outdoor central air unit during the winter can keep it from harmful weather or debris.
If your air conditioner requires more than regular maintenance, hire a licensed professional for your service work. Contact us today for more information on air conditioning maintenance, repair, or installation by calling 718-761-2300

Heating and Air Conditioning Maintenance

When dealing with the heating and air conditioning systems for your home, the old saying “If it ain’t broke, don’t fix it” can be risky. Your heating and air conditioning systems work to keep you and your family comfortable 24/7, so timely care is essential. The proper maintenance of these systems can keep the bills down and your home comfortable for many more years than a unit that is left untreated.
Why should you perform regular maintenance on your heating system? In addition to the units lasting longer, systems that are properly and regularly maintenance can provide a lot more for a house, and keep you from spending thousands fixing problems. Unchecked systems can cause a variety of issues in your home, such as Carbon Monoxide leaks, corrosion, soot buildup, heat loss, and more. The proper and regular maintenance, performed by a licensed professional 1 to 2 times a year, can lead to lower heating bills, less fire hazards, and can improve the overall efficiency of your heating unit.
Water heater maintenance is also vital in any home. Water heaters that are properly maintained can last longer and will keep extra costs down on the heating and water bills. Pipes are more prone to freezing during cold weather if the water heating system is not properly maintained.
Air conditioner systems should be serviced before the spring and fall, where you will need them to cool down your home. Air conditioners and central air systems should be regularly checked to maintain proper temperature control in a home.

HVAC Q & A

What do rating numbers mean?
The U.S. government requires an efficiency rating of all air conditioning and heating equipment. The rating reflects the percentage of energy used efficiently, with a higher rating indicating higher-efficiency. The next two topics address this issue in greater detail.

What is a SEER?
There are special names for the efficiency ratings of various types of equipment. Air conditioning equipment is rated by the Seasonal Energy Efficiency Rating, or SEER. The higher the SEER rating, the more efficient the unit.  New equipment manufactured today by the manufacturers must meet at least a 13.0 SEER rating, with some manufacturers producing equipment as high as 21.0 SEER.

What does HSPF stand for?
There are special names for the efficiency ratings of varying types of equipment. Air conditioning systems equipment with a heat pump function are rated by the Heating Seasonal Performance Factor. The higher the HSPF rating, the more efficient the unit.  HSPF is a ratio of BTU heat output over the heating season to watt-hours of electricity used.

What does AFUE stand for?
There are special names for the efficiency ratings of various types of equipment. Gas furnaces are rated according to their Annual Fuel Utilization Efficiency, or AFUE. The higher the AFUE rating, the more efficient the unit.  Natural draft furnaces or boilers typically have an efficiency rating of about 80%.  Manufacturers, like Lennox, have developed more efficient furnaces to operate at a 98% efficiency; meaning 98% of the energy costs you are putting into your furnace are being used to heat your home, unlike natural draft furnaces that only use 80% of your energy costs.  Boiler like the Weil McLain Ultra also provide high efficiency operation topping 95% AFUE.

Should outdoor units be covered in winter?
It is not recommended. Air conditioners can accidentally turned on by someone in your home without them knowing that the outdoor unit has been covered, whereby creating potential damage to your condenser and it's internal components.  The outdoor condenser is built to withstand the environment and should not be covered.

Should a thermostat be set to “auto” or “on”?
Preferably auto. That way, the fan operates only when the temperature requires it. This is the most used and the most efficient setting. However, there are advantages to using the “on” setting on your thermostat.  Air is constantly filtered through the unit’s air filter, and the constantly circulating air results in more even temperature throughout the house.

Can shrubs or flowers be planted around an outdoor unit?
Yes. However, we recommend that plants be no closer than 18 inches to the unit. This allows for plenty of room for air circulation in and out of the unit. Without this room for air circulation, the unit could overheat, resulting in a premature need for service.

If an outdoor unit needs replacing, should the indoor unit be replaced too?
It is recommended that both the indoor and outdoor equipment are replaced together, especially with the new EPA requirements to phase out R-22 refrigerant.  Currently, there are other options to replace just one of the components without the other, with the price of inefficiency and high energy costs.  That, however, is subject to change with the upgrades in building codes and National energy codes being enforced gradually, state by state.  The efficiency rating on a condenser is based on the entire system being replaced.

How do I know what size unit our house needs?
A Gregg Mechanical Corp. specialist will consider many factors before making a recommendation on the properly sized equiment for your home. Factors like the square footage of your house, the climate, the number and type of windows installed, insulation, and even the number of people living in the house are all part of the proper calculation of the air conditioning system needed for your complete comfort.

What is the difference between a split system and a package unit?
A split system uses indoor and outdoor components to provide a complete home comfort system.  A package unit or self-contained unit houses all the required coils, blowers, mechanical components and heating components needed to properly condition the space.  A package unit is typically used in commercial applications or in condominiums and apartments.

How Does It Work?

Welcome to Gregg Mechanical Corp., Staten Island's premier Heating and Air Conditioning contractor for residential and business HVAC repairs and new installations.

Air Conditioning: How Does It Work?
When you first enter a home or building that is using air conditioning you feel two things in the air, coolness and dryness. Both of these physical sensations are accomplished by the air conditioning unit. Although you feel cooler that is not really what the unit does. It removes heat and in the process also pulls moisture from the air. In other words, the air conditioner does not cool the air it removes the heat from the air. In the absence of heat is cold.

Part of the benefits of utilizing a central air conditioning system is the filtration of the air in your home which improves air quality.  The filter cleans the air by trapping dust and other small particles that are pulled in through the return.  The more efficient the air cleaner, the better the air quality in your home.  The air handler, the indoor unit, circulates the air while cooling and dehumidifyng it through the process called refrigeration. 

Refrigeration
Refrigeration cools a home by transferring heat inside a home to the outdoors. All central air conditioners employ two main units in this process – the indoor unit and the condensing unit.

The indoor unit
This unit removes undesirable indoor warmth and humidity. It includes the filter, the air handler or furnace, and the evaporator coil. The air handler or furnace blow filtered air through the evaporator coil. The evaporator coil is kept cold by the circulation of a substance called refrigerant.  The fan passes air across this coil and any moisture will condense and collect on the coil's fins. In this process the heat that is in the air is pulled out from the air stream. The absence of the heat is now cooled or cold air is created.  The cooler, drier air that continues through the air ducts is vented throughout your home to maintain your desired comfort level. Depending on the structure of your home, the ductwork may be in the ceiling or on the side walls of your rooms.

The condensing unit
Outdoors, at the condensing unit, an air conditioner releases the heat that was captured inside at the coil. The same refrigerant that absorbed the heat indoors at low pressure is now pressurized by the compressor and is circulated through another coil, the condensing coil. In the condensing coil, under high pressure, the refrigerant releases its heat very quickly, making the coil itself hot. A fan blows across the coil, cooling its temperature down and transferring the heat to the outside air.

Furnaces: How Does it Work?
The furnace is the most important component of a central heating system. It houses all the working parts. So when you replace the furnace, you replace the vital operating parts of your heating system. It is by choosing from among the different models and brands of furnaces available that you determine the quality and cost of your business’s heating for years to come.

Furnace
The Furnace is part of a forced-air system. Warm air is forced, or blown, through a system of air ducts to each of the rooms in your home.  Air drawn into the furnace passes through a filter, where dust and other small particles are trapped. A blower unit blows the filtered air through the furnace, and the air absorbs heat and distributes it throughout your home.

Gas Heat
If it is a gas furnace, the heat is supplied by the burning of natural gas. A mixture of gas and air flows into the burner and is ignited by the pilot. Combustion occurs, and warm air from the burner flame rises to fill a chamber known as a heat exchanger. The heat exchanger becomes hot. Office air passing around the heat exchanger absorbs that warmth, continues into the air ducts and the heat is distributed through the business.The by-products of combustion pass upward through a venting system and escape through a vent in the roof.

Electric Heat
If the furnace is electric, heat is generated by an electric heating element. Electric current traveling through the element creates heat. By the heat transfer processes called conduction and convection, heat is transferred into the air stream and flows through the air ducts into the rooms of the business.

The Thermostat
Whether you heat your home with gas or electricity, a wall thermostat will be installed. This measures room temperature and turns the central heating system off or on as the temperature rises or falls to designated levels. Careful location of the thermostat is an essential consideration in maintaining maximum comfort levels in your home.
