General Questions HVAC Maintenance, Filters & Everyday System Use
Why should I have a preventative maintenance plan?
Your HVAC system operates daily and experiences natural wear over time. Regular maintenance helps identify small issues, such as worn components or airflow restrictions, before they turn into costly repairs. Routine service also improves efficiency, extends the HVAC system lifespan, and reduces the likelihood of unexpected breakdowns.
How often should my HVAC system be serviced?
Most HVAC systems should be professionally serviced at least twice a year, once in the spring for your air conditioning system and once in the fall for your heating system. This ensures your air conditioning and heating equipment is prepared for seasonal demands.
What type of air filter should I use?
The right air filter depends on your HVAC system and indoor air quality needs. Standard filters help protect your system, while higher-efficiency pleated filters can improve air quality by capturing smaller particles such as dust and allergens. For best performance, filters should typically be replaced or cleaned monthly.
Should my thermostat be set to “auto” or “on”?
The “auto” setting is generally more energy efficient because the fan runs only when needed. The “on” setting continuously circulates air, which can help maintain more even temperatures but may increase energy usage.
Efficiency Ratings Understanding SEER, AFUE, HSPF & System Performance
What is a SEER rating?
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an air conditioning system operates over an entire cooling season. The higher the SEER rating, the more energy efficient the system, which can lead to lower utility costs.
What does EER mean?
EER (Energy Efficiency Ratio) measures how efficiently an air conditioning system performs at a specific outdoor temperature, typically 95°F. Like SEER, a higher EER rating indicates better efficiency.
What does HSPF stand for?
HSPF (Heating Seasonal Performance Factor) measures the heating efficiency of a heat pump over a full heating season. Higher ratings indicate better energy performance.
What is AFUE?
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a gas furnace converts fuel into heat. A higher AFUE rating means more efficient operation and less wasted energy.
Systems & Equipment Choosing the Right HVAC System for Your Home
Which HVAC system is best for my home?
The ideal system depends on several factors, including your home’s size, insulation, layout, ductwork, and overall energy needs. A professional in-home evaluation ensures the air conditioning and heating system is properly sized and configured for optimal comfort and efficiency.
What is the typical lifespan of an HVAC system?
Most air conditioning and heating systems can last 10–15 years or longer with proper maintenance. Regular service plays a key role in maximizing lifespan and performance.
Do I need to replace both indoor and outdoor units at the same time?
In most cases, yes. HVAC systems are designed to operate as matched systems, and replacing only one component can reduce efficiency and overall performance.
What is the difference between a split system and a package unit?
A split system consists of both indoor and outdoor components working together to heat and cool your home. A package unit contains all components in a single outdoor unit and is more commonly used in certain residential setups and commercial applications.
