You need a new HVAC system in Lewiston. Maybe you are adding central heating and cooling to a home that currently relies on window units, baseboard heaters, or wall units in Lewiston, ME. Maybe the existing system failed and repair costs relative to its age make a new installation the right investment in Lewiston. Maybe the system is 15 years old, still running, but you want to replace it before it fails at the worst possible time and on equipment that is 40 percent less efficient than what is available today in Lewiston, ME. In each case, you are making an investment that will determine how your home heats and cools for the next 15 to 20 years in Lewiston. And the decisions that determine whether that investment performs as expected are the sizing decision and the installation quality in Lewiston, ME.
Here is what most homeowners do not realize about HVAC equipment in Lewiston. The efficiency rating on a new HVAC system is the efficiency it achieves under laboratory test conditions in Lewiston, ME. What you actually experience in your home is the efficiency the installation produces in Lewiston. A high-efficiency system installed with an incorrect refrigerant charge operates at a significantly lower efficiency than its rating in Lewiston, ME. A correctly charged system installed on ductwork with significant leakage delivers a fraction of its rated cooling capacity to the living spaces in Lewiston. And a correctly charged, correctly installed system that is the wrong size for your home's actual load produces persistent humidity problems or inadequate comfort regardless of its efficiency rating in Lewiston, ME. The equipment rating is the ceiling. The installation quality determines whether you get anywhere near it in Lewiston.

The variables that determine real-world HVAC performance are all controlled during installation in Lewiston. Correct refrigerant charge, which affects both efficiency and cooling or heating capacity in Lewiston, ME. Correct airflow through the indoor coil, which affects heat transfer efficiency in Lewiston. Correct duct system compatibility, which determines how much of the system's conditioned air actually reaches the living spaces in Lewiston, ME. And correct system sizing, which determines whether the system produces the right amount of conditioning for the home's actual load in Lewiston. Every one of these variables is set during installation. Getting them right at installation is significantly easier than correcting them after the fact in Lewiston, ME.

An oversized HVAC system reaches the thermostat setpoint quickly without adequately conditioning the rest of the home or removing adequate humidity from the circulated air in Lewiston, ME. In cooling mode, the short cycles an oversized system produces do not run long enough to dehumidify effectively in Lewiston. Indoor humidity remains elevated despite the air conditioner running in Lewiston, ME. The home feels cold and clammy rather than cool and comfortable in Lewiston. And the frequent startup and shutdown cycles accumulate wear on the compressor that shortens the system's service life in Lewiston, ME.
An undersized HVAC system runs continuously in extreme weather without reaching the thermostat setpoint in Lewiston. The home is consistently warmer in summer and cooler in winter than the thermostat calls for during the most demanding weather in Lewiston, ME. The system runs at maximum capacity for extended periods, consuming maximum energy while delivering inadequate comfort in Lewiston.
MBM performs a Manual J load calculation for every HVAC installation in Lewiston. The calculation accounts for floor area, ceiling height, insulation R-values in all building assemblies, window area, orientation and SHGC, local design temperatures, and internal heat gains in Lewiston, ME. The output is the correct system capacity for the specific home in Lewiston. Not an estimate based on square footage alone in Lewiston, ME.
Manual J determines the correct system capacity. Manual D designs the duct system. Manual J determines the correct system capacity in Lewiston, ME. Manual D designs the duct system to correctly distribute the conditioned air that capacity produces to each room in Lewiston. A correctly sized system installed on an incorrectly designed duct system cannot deliver the right amount of conditioned air to each room regardless of its overall capacity in Lewiston, ME. Both calculations are required for a complete installation that performs correctly at the room level in Lewiston. MBM performs both as standard components of every complete HVAC installation in Lewiston, ME.

System electrical measurements confirming correct amperage draw. Overall system performance verified against expected performance in Lewiston.
A repair that costs more than 50 percent of the cost of a new system on a system that is more than 10 years old warrants serious consideration of replacement in Lewiston, ME. A second significant repair within a few seasons on an aging system suggests the system is entering the period of accelerating component failure in Lewiston.
A system that is 15 years old or more is in the final years of its designed service life regardless of whether it is currently operating in Lewiston. Pre-emptive replacement allows the homeowner to select the system, timing, and budget rather than making those decisions under the pressure of a failed system in the middle of summer or winter in Lewiston, ME.
Replacing a 10 SEER system with an 18 SEER system reduces cooling energy consumption by approximately 44 percent for the same cooling output in Lewiston, ME.
