The term HVAC stands for Heating, Ventilation, and Air Conditioning. This term is commonly used to refer to a complete heating and cooling system that includes ductwork, air filters, humidification controls, and registers. With HVAC systems, you can control the temperature, humidity, and air quality in your home, ensuring your comfort and health throughout the year.


To improve the efficiency of your HVAC system, it is recommended to frequently clean or replace the filters. Keeping the blower on helps to maintain constant airflow and even temperature distribution. Installing window treatments like drapes, shutters, blinds, or screens on south-facing or sun-exposed windows can also help to regulate the temperature.

There's no one-size-fits-all rule for sizing an HVAC system for a home. The only way to ensure you get the right size is to have a licensed professional evaluate your home's individual needs.

Manufacturers recommend regular maintenance to ensure that your heating and cooling equipment is operating at its optimal level, has an extended lifespan, and safety. 


A clogged dirt furnace filter can impede the airflow and reduce the efficiency of your furnace. This can lead to higher energy costs and poor indoor air quality. By regularly replacing your furnace filter, you improve air quality, lower energy bills, increase furnace efficiency, and reduce allergy symptoms.



The age of your AC is a key factor when deciding to repair or replace it. A technician can advise you on repair costs versus a new system. Consider energy efficiency and the cost of major repairs, such as refrigerant leaks or a faulty compressor, before making a decision.

Regularly changing filters is the most important maintenance for your AC. Keep outdoor units free of clutter and pets, as pet urine can cause damage. Avoid using weed trimmers near the unit to prevent damage to the wiring. For other maintenance, it is recommended to reach out to qualified professionals for assistance.

Choosing the right size of AC for your home is important for optimal performance and energy efficiency. The bigger system is not necessarily better. The size of the AC unit you need depends on various factors, such as the size of your home, the level of insulation, and the number of windows. Our licensed technician will do a heat load calculation in order to properly size AC unit and provide recommendations.

Indoor air can become dry when outdoor air enters a home and gets heated, resulting in increased static electricity and potential sinus problems. Installing a humidifier can help alleviate these issues by adding moisture back into the air, maintaining a comfortable humidity level of 35-45%, and reducing the chances of sinus problems.

The frequency with which you should change your air filter depends on several factors, such as the type of filter you have, the size of your home, the number of occupants, and the presence of pets or allergies. As a best practice, it is recommended that you change air filter every 1-3 months.



SEER – Seasonal Energy Efficiency Ratio is the most commonly used efficiency rating for both heat pumps in cooling mode and air conditioners.

EER stands for "Energy Efficiency Ratio". It is a measure of an air conditioning system's efficiency at a specific outdoor temperature.

AFUE stands for Annual Fuel Utilization Efficiency. It is a rating used for furnaces and boilers that measures the efficiency of converting fuel to heat over the course of a year. The higher the AFUE rating, the more efficient the unit is at converting fuel to heat, which means lower energy costs and reduced environmental impact.
