Frequently asked questions

What does HVAC stand for?

HVAC stands for Heating, Ventilation, and Air Conditioning. These systems regulate indoor temperature, humidity, and air quality to ensure comfort and safety in your home.

How long do HVAC systems typically last?

Most HVAC systems have a lifespan of 8 to 15 years. Regular maintenance can extend their longevity, while factors like usage patterns and environmental conditions can influence their durability.

What is a MERV rating?

MERV (Minimum Efficiency Reporting Value) rates the effectiveness of air filters in trapping airborne particles. Higher MERV ratings indicate better filtration, which can improve indoor air quality.

How often should I service my HVAC system?

It’s recommended to have your HVAC system inspected and serviced at least twice a year. Ideally, schedule maintenance for your heating system in the fall and your cooling system in the spring to ensure optimal performance.

Where is my air filter located?

The location of your air filter can vary depending on your system’s design. Common locations include inside the furnace or air handler unit, behind return air vents, or in a dedicated filter slot or compartment.

How do I know what size filter to use?

The correct filter size is usually printed on the edge of the existing filter. If you’re unsure, consult your HVAC system’s manual or contact your dealer for guidance.

How often should I replace my HVAC filter?

For one-inch thick filters, replace monthly. Two-inch or high-capacity pleated filters can be changed every other month or about six times per year.

What is the difference between variable-speed and two-stage systems?

Variable-speed systems operate in longer, lower-speed cycles, providing consistent comfort and energy efficiency. Two-stage systems have two levels of operation—high for extreme temperatures and low for milder days—offering improved efficiency over single-stage systems.

Why would I choose a heat pump for my home?

Heat pumps provide both heating and cooling, making them versatile for year-round comfort. They are especially efficient in moderate climates and can be an energy-saving alternative to traditional systems.

What does BTU stand for in HVAC terms?

BTU stands for British Thermal Unit. It’s a measurement of energy, specifically the amount required to raise the temperature of one pound of water by one degree Fahrenheit.

Is it advisable to adjust my thermostat when I'm not home?

While setting back your thermostat can save energy, drastic changes might lead to discomfort and increased humidity or dryness. A moderate adjustment of 2–3 degrees is recommended. For extended absences, like vacations, more significant adjustments can be beneficial, but it’s essential to consider potential impacts on home humidity and comfort.

Should I cover my outdoor air conditioning unit during winter?

It’s not recommended to fully wrap your A/C unit, as this can trap moisture and invite pests, leading to potential damage.
