HVAC System Tips: Find your trusted qualified consultant. Find a good HVAC company or technician to test and repair the device if you are a home owner or a small business building owner. Find a commercial HVAC company for normal maintenance if you are a large commercial building owner and a good mechanical engineer for specific guidance. I do not suggest using the HVAC Company’s mechanical engineer; find a third party engineer for unbiased information.Browse plumber
Check the load of your HVAC system. Home owners should use the calculation method of ACCA’s Manual J and all others should have a mechanical engineer load. Commercial buildings have more coding criteria, minimum ventilation levels, etc., and are individual to each building.
Reduction load-Read the above data.
Pick the size of your charging equipment. NEVER ALWAY! More-is-better is not acceptable in HVAC systems. It will cost more to buy and run the equipment. Get the first time the load and the selection of equipment.
Buy high performance or appliances from Energy Star. Many of the new systems have fans and compressors with variable speed drives. This will be paid back several times over the years of possession. Compare regular efficiency equipment in terms of initial cost and life cycle costs with high efficiency equipment. This knowledge can be learned from any successful HVAC business or mechanical engineer.
Allow for any air expelled from the building some form of energy recovery and use it to prepare the incoming fresh air. This is the air you paid to clean, so it should be a priority to remove some of the heat before wasting it.
For large commercial buildings, consider conditioning the outside air with a dedicated outside air unit. In most cases, this will eliminate any issues related to humidity control. It will also increase the comfort of the occupant and allow the equipment to be further reduced.
Commercial buildings on their appliances should find economizers. Most of the existing codes need more than 15 tons of equipment economizers. Such systems are often available at a low incremental cost when the outside temperature (sometimes moisture) is lower than the inside temperature of fresh air.
Programable thermostats should be used by homeowners and small commercial building owners. A Direct Digital Control (DDC) system should be built by commercial construction owners. In a small amount of time, the investment in either will pay back more than the value.
