FAQs

The seasonal energy efficiency ratio (SEER) is a measure of an air conditioner or air-source heat pump's efficiency. It's calculated by dividing the cooling output over a specific season by the total energy consumed during that same period. A higher SEER rating indicates a more efficient cooling system.

The SEER rating can vary due to several factors. Each split system cooling unit has a nominal SEER rating, but the actual rating depends on the combination of equipment installed in your home. Both the outdoor unit (heat pump or air conditioner) and indoor components (evaporator coil and furnace or air handler) contribute to the overall SEER rating. Your HVAC contractor can advise on potential upgrades for a higher rating.

Regular HVAC maintenance is crucial for optimal performance and longevity of your heating and cooling systems. These systems undergo significant wear and tear due to constant operation. Preventive maintenance helps identify potential issues early, such as leaks, rust, frayed wires, or corroded contacts. It also ensures maximum efficiency and can prevent many common equipment failures, ultimately extending the life of your units.

All heating and cooling equipment should receive annual professional maintenance. For boilers and furnaces, inspections should cover ductwork, pipes, dampers, valves, chimneys, registers, radiators, pumps, blowers, fuel lines, and oil tanks. Heat pump and air conditioning unit inspections should include examinations of the fan, compressor, indoor and outdoor coils, and refrigerant lines.

Programmable thermostats offer improved accuracy and efficiency compared to mercury-based models. They allow you to pre-set temperature adjustments for different times of the day, eliminating the need for manual adjustments. By scheduling temperature changes to align with your daily routine, you can reduce energy consumption and costs without sacrificing comfort. Our technicians can provide guidance on effectively using your programmable thermostat.

Some HVAC units require brand-specific filters that may not be available in standard retail stores. These specialized filters often use different or higher-quality materials than disposable filters. We recommend consulting with your local dealer to find the appropriate filter for your air conditioner. It's worth noting that some filters are reusable and can be cleaned by hand with cold water.

Determining the right size HVAC equipment involves considering multiple factors, including your home's square footage, insulation, window configuration, geographic location, and duct arrangement. Our technicians can perform an in-home load analysis to recommend the most suitable equipment for your specific needs. Generally, one ton of air conditioning can cool between 300 to 800 square feet, depending on your home's construction. A professional evaluation ensures you get the correctly sized system for optimal performance.

On average, HVAC systems typically last about 10 years. However, the lifespan of your specific unit may vary. Factors that influence equipment longevity include the type of system, local climate conditions, and the frequency of routine maintenance. Regular professional servicing can significantly extend the operational life of your HVAC system.
