Heating Installation

The Importance of Proper Heating and Air Conditioning Installation

The most important day in the life of your heater and air conditioner is the day it is installed. Proper installation and choosing the right size accounts for almost 75% of the operating efficiency and performance of the system you buy.

According to the ACCA (Air Conditioning Contractors of America) only 28% of homeowners who replaced their heating and air conditioning systems last year noticed an improvement in the performance of their new system. The other 72% felt that the primary reason they were replacing their system was not resolved. The reason is simple: a heating and air conditioning system is not a commodity like a toaster oven, washer, or dryer. Its efficiency, reliability, performance and safety are directly related to the quality of installation, proper sizing and air distribution. It’s important when you spend thousands of your hard earned dollars on a new system that you get the right equipment for your particular needs and a guarantee that the system will perform to your expectations.

Installation Standards

As part of every installation, MrCentral heating and air conditioning technicians follow a comprehensive set of procedures to ensure that your system is properly connected and functioning at optimal levels.

Procedure: ALWAYS purge nitrogen through the copper tubing and coil while performing welding procedures
Purpose: To ensure maximum refrigerant flow by eliminating contaminating carbon build-up during the welding process.
Procedure: EVACUATE system with service caps in place and secure to prevent air and moisture from entering the system
Purpose: To remove all moisture, which prevents rapid to premature compressor failure.
Procedure: LEAK TEST with nitrogen after welding is completed (Fill system to 150 psig with nitrogen and hold)
Purpose: To prevent future service calls, reduced capacity and longer lifespan by having a refrigerant system that is leak free. Any system operating with an insufficient amount of refrigerant due to any size leak causes higher electric consumption, decreased capacity and shorter lifespan of the equipment.
Procedure: EVACUATE system to 400 microns or less with a digitally calibrated micron gauge and use a 4-Valve Manifold gauge set, so that you can isolate your micron reading from the pump
Purpose: A proper vacuum guarantees a dehydrated system, as well as a leak-free refrigerant line system. Dehydration prevents any acid buildup that will lead to future compressor failure.
Procedure: ALWAYS use new refrigerant lines on every installation. (There are no special cases to this rule)!
Purpose: Any refrigerant line system that has been used by a previous system has some type of contamination in the lines. This contamination will lead to blockages and restrictions which cause premature failure of the system.
Procedure: EVACUATE every new system with NEW OIL every time
Purpose: Once the oil in a vacuum is used, the oil becomes fully saturated with moisture. The proper vacuum level required is not achievable when reusing this oil.
Procedure: ALWAYS use separate manifold gauges for R-410A and R-22 systems. DO NOT USE combination gauges for R-410A and R-22
Purpose: The mixing of different refrigerants is similar to using different blood types. It doesn’t work.
Procedure: ALWAYS cut copper tubing with a sharp wheel and carefully ream out inside while tilting tubing down to prevent shavings from entering
Purpose: Any foreign body in the refrigerant line system can cause restrictions that could lead to decreased capacity and/or equipment failure.
Procedure: ALWAYS introduce refrigerant VAPOR into the line set and indoor coil to break vacuum and STOP at 25 psig pressure. Then remove service valve caps to open system. DO NOT remove service caps while system is in a vacuum
Purpose: The state of the refrigerant system needs to be changed from a negative to a positive pressure to be sure that no outside air enters the system upon start up.
Procedure: ALWAYS check and set proper air flow on indoor unit to match required system air flow (Example: Variable Speed switches)
Purpose: Improper air flow setting will not allow a system to charge correctly or gas pressure set accurately to achieve a proper temperature drop/rise. It is one of the most important parts of the start-up.
Procedure: UTILIZE manufacturer’s literature and information to properly set charge on system. (Fill out essential readings paperwork)
Purpose: Proper operation of the equipment guarantees the lowest possible energy costs and maximum performance.
Procedure: ALWAYS STAGE all electric backup heat packages on every system that has a heat package of 15 kw and higher
Purpose: The most economical and comfortable way to utilize electric backup heat is the staging of the heating elements. This procedure allows you to use only what you need, which in turn saves you hundreds of dollars.
Procedure: ALWAYS use a digital/programmable thermostat control center
Purpose: Maintaining the proper comfort levels within a home is best accomplished by utilizing a control center that monitors staging of the heating/cooling, humidification, dehumidification, filter change reminders, as well as flexible times for setback saving.
