The most generally known efficiency rating is Seasonal Energy Efficiency Rating (SEER). SEER 13 is the minimum efficiency you should consider, but higher efficiencies are likely to be cost effective. Some central air systems have SEERs of 16. In hot, dry climates you should look at the Energy Efficiency Rating (EER), which denotes how well the system will work at peak conditions. Also look for Energy Star-rated systems for the best energy efficiency.
Room pressure can be either positive or negative with respect to outside the room. Positive pressure occurs when there is more air being supplied than exhausted, and is common to reduce the infiltration of outside contaminants.
You already know that a thermostat allows you to adjust and control the temperature of your home. What you might not know, though, is that with some newer HVAC systems you’ll need to make sure that the thermostat you are using is actually compatible with that system (many manufactures sell compatible thermostats for this reason).
HVAC has nothing to do with vacuuming, despite being called that. It is actually for the three functions the system offers. They are:
Dry indoor air can make you feel less glamorous, with dry hands, allergies, and even skin rashes.
Some benefits of forced air systems, which are now widely used in churches, schools, and high-end residences, are

If you live in hot or humid climates, it might not be possible to maintain thermal comfort through natural ventilation. Air conditioning systems are used as either backups or additional cooling. Air-side conditioners use outside air to condition rooms, but they do this using fans, dampers and control systems that introduce and distribute cool outdoors air as appropriate.
Modern buildings incorporate the design, construction, and control of these functions into one or several HVAC systems. For small buildings, contractors typically determine the required system capacity and design the system.
This is most likely what you associate with an HVAC system. The outdoor unit houses the fan, which allows for air flow. Pro tip - Keep your fan clean and free of vegetation. If they become entangled with plants, this can cause serious problems.
Your best and only resource for evaluating your HVAC needs is a dealer. They will work with your budget and help you find the best solution for you. They can help with:
Mechanical, or forced, ventilation is provided by an air handler (AHU) and used to control indoor air quality. Excess humidity, odors, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates more energy is required to remove excess moisture from ventilation air.
Your air return is the part of your system that marks the starting point of the ventilation cycle. This return sucks in air, draws it through a filter, and then passes it into the main system. Pro tip: Make sure to dust your returns frequently as debris and dust can easily build up on your filters.
When it comes to choosing the right heating and cooling system for your home, climate is important. In the cold north and south, heating and cooling requirements will be different. Depending on where you live, installation costs may vary up to 20%.
HVAC Pros guarantee our workmanship and we’ll treat your home with care and respect. And when it comes to service, we have knowledgeable technicians who will keep your equipment running smoothly for years to come.
Failure to keep the condenser clean will eventually result in harm to the compressor because the condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) and the heat generated by the electric motor driving the compressor.
Industrial fans are great for commercial spaces, such as warehouses, shops, gyms, and other commercial areas. These fans are great for cooling large areas and preserving floor space at high speeds.
HVAC stands for heating, ventilation and air conditioning systems. This system is responsible for heating and cooling your home and includes products like furnaces, air conditioners, heat pumps as well as ductwork, thermostats and other home comfort controls.
The compressor, which is part of an outdoor unit, converts refrigerant into liquid and sends it back to the coils. Pro tip: Check your compressor if something isn’t working right. This is often the root cause of system failures.

Richmond (/ˈrɪtʃmənd/) is the capital city of the Commonwealth of Virginia in the United States. It is the center of the Richmond Metropolitan Statistical Area and the Greater Richmond Region. Richmond was incorporated in 1742 and has been an independent city since 1871. At the 2010 census, the city's population was 204,214;[6] in 2020, the population had grown to 226,610,[6] making Richmond the fourth-most populous city in Virginia. The Richmond Metropolitan Area has a population of 1,260,029, the third-most populous metro in the state.
Richmond is at the fall line of the James River, 44 mi (71 km) west of Williamsburg, 66 mi (106 km) east of Charlottesville, 91 mi (146 km) east of Lynchburg and 92 mi (148 km) south of Washington, D.C. Surrounded by Henrico and Chesterfield counties, the city is at the intersections of Interstate 95 and Interstate 64 and encircled by Interstate 295, Virginia State Route 150 and Virginia State Route 288. Major suburbs include Midlothian to the southwest, Chesterfield to the south, Varina to the southeast, Sandston to the east, Glen Allen to the north and west, Short Pump to the west and Mechanicsville to the northeast.[7][8]
The site of Richmond had been an important village of the Powhatan Confederacy, and was briefly settled by English colonists from Jamestown from 1609 to 1611. The present city of Richmond was founded in 1737. It became the capital of the Colony and Dominion of Virginia in 1780, replacing Williamsburg. During the Revolutionary War period, several notable events occurred in the city, including Patrick Henry's "Give me liberty, or give me death!" speech in 1775 at St. John's Church, and the passage of the Virginia Statute for Religious Freedom written by Thomas Jefferson. During the American Civil War, Richmond was the capital of the Confederacy. It entered the 20th century with one of the world's first successful electric streetcar systems. The Jackson Ward neighborhood is a traditional hub of African-American commerce and culture.
Richmond's economy is primarily driven by law, finance, and government, with federal, state, and local governmental agencies, as well as notable legal and banking firms in the downtown area. The city is home to both a U.S. Court of Appeals, one of 13 such courts, and a Federal Reserve Bank, one of 12 such banks. There are several Fortune 500 companies headquartered in the city including: Dominion Energy, WestRock, Performance Food Group, CarMax, ARKO, and Altria with others, such as Markel, in the metropolitan area.[9][10][11]
