You need a new HVAC system in Lisbon. Maybe you are adding central heating and cooling to a home that currently relies on window units, baseboard heaters, or wall units in Lisbon, ME. Maybe the existing system failed and repair costs relative to its age make a new installation the right investment in Lisbon. 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 Lisbon, 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 Lisbon. And the decisions that determine whether that investment performs as expected are the sizing decision and the installation quality in Lisbon, ME.
Here is what most homeowners do not realize about HVAC equipment in Lisbon. The efficiency rating on a new HVAC system is the efficiency it achieves under laboratory test conditions in Lisbon, ME. What you actually experience in your home is the efficiency the installation produces in Lisbon. A high-efficiency system installed with an incorrect refrigerant charge operates at a significantly lower efficiency than its rating in Lisbon, ME. A correctly charged system installed on ductwork with significant leakage delivers a fraction of its rated cooling capacity to the living spaces in Lisbon. 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 Lisbon, ME. The equipment rating is the ceiling. The installation quality determines whether you get anywhere near it in Lisbon.

The variables that determine real-world HVAC performance are all controlled during installation in Lisbon. Correct refrigerant charge, which affects both efficiency and cooling or heating capacity in Lisbon, ME. Correct airflow through the indoor coil, which affects heat transfer efficiency in Lisbon. Correct duct system compatibility, which determines how much of the system's conditioned air actually reaches the living spaces in Lisbon, ME. And correct system sizing, which determines whether the system produces the right amount of conditioning for the home's actual load in Lisbon. Every one of these variables is set during installation. Getting them right at installation is significantly easier than correcting them after the fact in Lisbon, 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 Lisbon, ME. In cooling mode, the short cycles an oversized system produces do not run long enough to dehumidify effectively in Lisbon. Indoor humidity remains elevated despite the air conditioner running in Lisbon, ME. The home feels cold and clammy rather than cool and comfortable in Lisbon. And the frequent startup and shutdown cycles accumulate wear on the compressor that shortens the system's service life in Lisbon, ME.
An undersized HVAC system runs continuously in extreme weather without reaching the thermostat setpoint in Lisbon. The home is consistently warmer in summer and cooler in winter than the thermostat calls for during the most demanding weather in Lisbon, ME. The system runs at maximum capacity for extended periods, consuming maximum energy while delivering inadequate comfort in Lisbon.
MBM performs a Manual J load calculation for every HVAC installation in Lisbon. 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 Lisbon, ME. The output is the correct system capacity for the specific home in Lisbon. Not an estimate based on square footage alone in Lisbon, ME.
Manual J determines the correct system capacity. Manual D designs the duct system. Manual J determines the correct system capacity in Lisbon, ME. Manual D designs the duct system to correctly distribute the conditioned air that capacity produces to each room in Lisbon. 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 Lisbon, ME. Both calculations are required for a complete installation that performs correctly at the room level in Lisbon. MBM performs both as standard components of every complete HVAC installation in Lisbon, ME.

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 Lisbon, 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 Lisbon.
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 Lisbon. 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 Lisbon, ME.
