Your AC system has reached the end of its service life in Marlborough. Or it failed and repair costs relative to its age make replacement the better decision in Marlborough, MA. Or you are adding central cooling to a home that has not had it and you are ready to stop managing summer heat with window units in Marlborough. Whatever the specific situation, you are making a significant investment in home comfort and energy efficiency that will affect your home for the next 15 to 20 years in Marlborough, MA. And the two decisions that will determine whether that investment performs as you expect are the sizing decision and the installation quality in Marlborough. Both matter more than the brand of equipment on the equipment pad in Marlborough, MA.
A high-efficiency AC system installed with an incorrect refrigerant charge performs at significantly reduced efficiency in Marlborough, MA. A system installed on a duct system with significant leakage delivers a fraction of its rated cooling capacity to the living spaces in Marlborough. A system that is physically installed correctly but sized incorrectly for the home's actual cooling load operates in a mode that produces either persistent humidity problems or inadequate cooling capacity regardless of the efficiency rating on the equipment label in Marlborough, MA. The equipment's rated efficiency is the efficiency it achieves under laboratory conditions. What you actually experience in your home is the efficiency the installation produces in Marlborough.

A central AC system has a rated SEER efficiency that represents its performance under standardized test conditions in Marlborough. In a real residential installation, the actual efficiency the system achieves depends on correct refrigerant charge, correct airflow through the indoor coil, the condition of the duct system the system is installed on, and correct sizing for the specific home in Marlborough, MA. An installation that misses on any of these variables produces a system that underperforms its rating in Marlborough. An installation that gets all of them right produces the efficiency you are paying for in Marlborough, MA.
An oversized AC system cools the thermostat location to setpoint before the rest of the home has reached the same temperature in Marlborough, MA. The system shuts off having satisfied the thermostat but having run for too short a cycle to remove adequate humidity from the circulated air in Marlborough. The result is a home that feels cold and clammy rather than cool and comfortable in Marlborough, MA. Indoor relative humidity remains elevated despite the air conditioner running in Marlborough. Mold growth on surfaces throughout the home is more common in homes with oversized AC systems than in correctly sized homes in Marlborough, MA. And the short cycling produces wear on the compressor at an accelerated rate in Marlborough.
An undersized AC system runs continuously in hot weather without reaching the thermostat setpoint in Marlborough. The home is consistently warmer than the thermostat calls for in Marlborough, MA. The system runs at maximum capacity for extended periods, accumulating wear faster than a correctly sized system in Marlborough. Energy bills are high because the system is running more hours per day than a correctly sized system would need to in Marlborough, MA. And occupant comfort is poor because the home never reaches the set temperature in the hottest weather when cooling is most needed in Marlborough.
Air America performs a Manual J load calculation for every AC installation in Marlborough. The calculation accounts for every variable that affects the home's actual cooling load including floor area, ceiling height, insulation R-values in all building assemblies, window area and SHGC, local design temperature, and internal heat gains from occupants and appliances in Marlborough, MA. The calculation output is the correct system capacity for the specific home in Marlborough. Not an estimate based on square footage alone. A full load calculation in Marlborough, MA.
The rule of thumb sizing method of one ton of cooling per 500 to 600 square feet of floor area produces wildly inaccurate results for homes that deviate from the assumptions embedded in that rule in Marlborough. A well-insulated home with efficient windows may need significantly less cooling capacity per square foot than the rule assumes in Marlborough, MA. A home with large south-facing windows, high ceilings, and minimal insulation may need significantly more in Marlborough. Manual J accounts for all of these variables and produces the correct capacity for the specific home rather than an estimate for an average home of that size in Marlborough, MA.

After installation is complete, Air America verifies the refrigerant charge using gauges connected to the refrigerant circuit in Marlborough. The system is charged to the manufacturer's specified refrigerant quantity adjusted for the specific installation's line set length in Marlborough, MA. A correct refrigerant charge is one of the most critical variables for achieving the system's rated efficiency in Marlborough.
After the refrigerant charge is verified, Air America commissions the system and measures its performance in Marlborough, MA. Supply air temperature at multiple registers. Return air temperature and humidity. System electrical measurements to confirm correct amperage draw. And overall system performance verified against the expected performance for the specific system and conditions in Marlborough.
An AC system approaching or past its 15-year service life that requires a major repair warrants a replacement comparison in Marlborough, MA. A system that has required multiple repairs in recent seasons is communicating that its remaining service life is limited in Marlborough. A system using R-22 refrigerant that has phased out of production faces increasingly expensive refrigerant costs for any refrigerant-related repair in Marlborough, MA. And a system that is significantly less efficient than current equipment is costing the homeowner measurably more in energy every year it continues to operate in Marlborough.
A new high-efficiency AC system replacing a 15-year-old standard efficiency system can reduce cooling energy consumption by 30 to 50 percent depending on the efficiency ratings being compared in Marlborough. A correctly sized replacement system eliminates the short cycling humidity problems that an oversized original installation may have been producing in Marlborough, MA. And a variable speed replacement system produces a level of indoor comfort and humidity control that single-stage systems cannot match in Marlborough.
