A/C Facts

Some air conditioning problems can double operating costs without reducing comfort.

A Freon undercharge of only 10% can increase operating costs by almost 20%.

Up to 80% of all air conditioning compressor failures could be eliminated if the problems that lead up to failure were corrected in a timely manner.

A dirty evaporator, condenser and blower could increase air conditioning or heat pump electrical usage by 50% or more.

Just a 100th of an inch of dirt or film on an evaporator coil can reduce cooling efficiency by 5%.

Proper care of your equipment can save you real dollars on your utility bills.

All leading manufacturers recommend regular maintenance to maintain peak performance.

 

Air Conditioning
................................

Like our winters getting colder, our summer days are becoming hotter and these days an air conditioning system is considered to be a key component in the maintenance of any building, improving the air quality within. An air conditioning system provides ventilation while cooling down your space and keeping the humidity down. Humidity properly controlled by an air conditioning system is a key measure in preventing moisture and mold related issues.

S & J Jamrog has been servicing and installing all brands of air conditioning systems since 1965. Our technicians are all EPA certified and provide expert troubleshooting, diagnosis and repair. We offer 24 hour emergency service and routine A/C maintenance plans.

Some of our services include:

  • Residential Routine Maintenance
  • Commercial Routine Maintenance
  • New Air Conditioning Systems
  • Rooftop Air Conditioning units
  • Mini Split Air Conditioning
  • HIV Air Conditioning Units
  • Packaged Air Conditioning Systems
  • Chillers

New Air Conditioning Systems

We offer complete service and installation of central air conditioning systems. If you don’t have ductwork and you were told you cannot install central air, we can. We can properly install air conditioning in virtually any space.

Packaged/Rooftop Air Conditioning Systems
These fully self-contained air conditioners are ready to be used for rooftop or ground mount residential or commercial applications. Your building’s air ducting connects to the unit’s side or bottom – your choice. We offer expert service and complete installation on all makes of packaged air conditioning systems.

Mini Split Air Conditioning
A mini split AC unit is much like a central air unit in the way it physically operates, but it is split up between the inside and outside. You will have an exterior unit which is attached to the inside unit by only a small line of coolant. It's quiet and efficient. These units attach to the wall or ceiling, which is especially helpful when you office doesn't have windows available for the classic window unit. The mini split AC unit is very energy efficient, and some units have earned an Energy Star rating. These units are incredible for offices, computer rooms, break rooms, offices, and much more.

High Velocity Air Conditioning
High velocity air conditioning unit is a central air conditioner that circulates air through the room using aspiration, or a strong burst of air. A conventional central AC unit uses forced air principles instead. Cool air enters the room near the ceiling and slowly drifts downward. High velocity air conditioning often means more consistent cooling throughout your house and less air stagnation. In a high velocity air conditioning unit, air doesn’t flow through large metal ducts. Instead, supply lines consist of two-inch, insulated tubing. This means a high velocity unit may fit in spaces where a conventional AC unit could not. We service and install High Velocity Air Conditioning systems.

Chillers
In air conditioning systems, chilled water is typically distributed to heat exchangers, or coils, in air handling units, which cool the air in its respective space(s), and then the chilled water is re-circulated back to the chiller to be cooled again. These cooling coils transfer sensible heat and latent heat from the air to the chilled water, thus cooling and usually dehumidifying the air stream. We offer service and installation on chiller systems.
