We have a wide selection of heating systems and cooling systems, and our team of experts can help you with repairs, choosing an HVAC system, or installing a new unit and regular maintenance.

What is an HVAC?

From baseboard heaters and air coolers to air purifiers, floor registers, HVAC ducting and duct tape accessories, we've got your heating and cooling needs covered.

HVAC is an acronym for heating, ventilation and air conditioning. The heating process increases the temperature of your home’s air, bringing it to a warmer level during cold winter months. The process of ventilation constantly exchanges indoor air with air from outside, providing healthy air quality inside your home. In warmer months, air conditioning cools the air brought in from outside and removes the humidity to maintain a comfortable and safe temperature.

Choosing the Right Fan

Fans can also be a great heating and cooling choice. Floor fans are designed to sit on the floor and circulate air throughout the immediate area. We also have a large selection of sleek and stylish ceiling fans.

Tower fans are named for their streamlined, tower-like design. They fit well in corners and tighter spaces and operate quietly, making them a great option for bedrooms and kitchens. Many tower fans come with a remote control for your convenience.

Wall mounted fans come in indoor and outdoor varieties, and some work well in either environment. Many include varying speeds and oscillating functions, while some also offer remote control access.

Industrial fans are ideal for commercial spaces like warehouses, gyms and shops. These types of fans help preserve floor space while cooling larger areas at heavy-duty speeds.

Desk fans are small, portable and easy to maneuver atop counters, tables and other hard surfaces. These are some of the best fans for bedroom nightstands and small workstations.

Bathroom exhaust fans keep stale and humid air out of the most essential rooms in our homes. When shopping for a ventilation fan you should consider the room size, sound level and light choices.

Does My Home Need a Humidifier or Dehumidifier?

The quality of air that circulates in your home is something to consider when choosing HVAC for residential. Start with choosing the best air filter for your home. The Home Depot uses this filter performance rating (FPR) to identify air filter brands as premium, best, better and good. Professionals use an air filter rating system of Minimum Efficiency Reporting Value (MERV) as an industry standard and the ratings do not equate.

Humidifiers capture dry heat and air throughout your home by infusing moisture into dry spaces. Dehumidifiers keep your home air fresh by reducing mildew odors, allergens and moisture. Consider your location and the climate to determine which appliance will balance the level of humidity in your home.
