A house or a commercial building is made of many different working parts that must come together to form a complete whole, from the plumbing to the electrical power to the air conditioning and heating to Internet services. So long as all these utilities are working fine, a building is comfortable and practical to live in, and utility bills will stay under control. But if the commercial HVAC system is faulty in a home or a public building like an office or bank, such as if it is dirty or damaged, real problems may crop up. A damaged, worn out, or clogged commercial HVAC system will waste a lot of electricity trying to constantly make up for unstable interior temperatures or weak blower fans. HVAC contractors can be hired if there is a problem with a commercial HVAC system in a home or building, and heating and cooling systems may even need to be replaced entirely if they are badly damaged enough or simply very old. HVAC maintenance may range from cleaning out an outdoor unit all the way to overhauling the entire thing.
Energy Waste and a Commercial HVAC System
How is a commercial HVAC system linked to rates of energy waste in buildings? It is easy to see how faulty HVAC systems can waste power based on how just over 50% of a home’s energy goes towards the heating and cooling systems. Two in three American homes have an air conditioner unit, but these heating and cooling units are not always up for the job. If a heating and cooling system has clogged vents or air ducts, the blower fans have to work extra hard to get cooled or heated air through them and modify the building’s climate, and this wastes a lot of power trying to work through that grime. And if the blower fans themselves are coated with grime, such as pollen, rat droppings, dust, or spiderwebs, they will always be inefficient and will have to work extra hard to deliver the necessary cool or warm air. Rips or holes in the air ducts will leak warm or cool air, further dampening the system’s efficiency.
And even if the heating and cooling system itself is in fine working order, the building itself might be sabotaging the climate control. Nearly 25% of a home’s heat loss can be attributed to cracks and holes in the windows, door frame, walls, or even the attic or roof, and drafty windows or doors can quickly leak warm or cool air. The same is true if the walls have thin or nonexistent insulation, or if the attic’s insulation is poor or if the roof has holes. Escaping warm air in winter or leaking cool air in summer can disrupt the home’s internal temperature and force the HVAC system to constantly adjust for the loss, which cranks up the electric bill fast. What can be done?
Fixes for a Commercial HVAC Unit
In some cases, addressing the energy waste of a home’s heating or cooling system means fixing the home itself if that is the problem. Drafty windows or doors can be replaced, and bare windows can have blinds, screens, or drapes set up, any form of window treatment that is needed. Bare windows let in a lot of hot sunlight in spring and summer, which can overheat a room and force the air conditioner to keep turning back on. Window blinds and screens can help keep hot sunlight out and also help maintain privacy. Meanwhile, bare windows might also leak warm air in winter, so drapes can help prevent that. Wall insulation can be replaced as needed, such as spray foam insulation for the walls or attic.
A dirty or damaged HVAC system needs the attention of professional crews. Once repair crews arrive, they can fix or replace damaged air duct sections or remove squirrel or rat nests, and they can also clean off or replace blower fans to restore their power and efficiency, and they can also clean out or fix outdoor units. And a very old HVAC system can be replaced entirely with a new ones that is more powerful and also meets modern electricity efficiency standards.
