A commercial HVAC (heating, ventilating, and air cooling) system has the same function as a residential HVAC system. The idea is to maintain the environment during a chilly night or a 72-degree hot summer day. Overall, the system's principle is the same, however, it is a more robust version of residential HVAC, capable of supporting large complexes. The heating is achieved by burning fuel like gas, oil, or electricity, and the cooling is achieved by a natural process where hot indoor air is extracted and cooled using a refrigerant or water colling system. Ventilation is provided by suction fans and filters.

Commercial HVAC systems are best for large buildings, regardless of their nature. These systems can cool or heat air, distribute the load among various mechanical systems and control the environment using simple thermostats. All this makes them economical and reliable for busy, buildings with heavy human traffic. Commercial HVAC is best for proving heating, ventilation, and cooling to individual floors of large buildings and complex structures. These systems are actively employed in industrial, commercial, and institutional buildings to adjust the variable outdoor air conditions with the required indoor ones as per the occupant’s requirement.

Single Split systems are the most economical type of HVAC system and are capable of supporting most standard-size buildings. They heat or cool individual rooms using separate thermostats or Direct Digital Controls (DDC), making them perfect for a plaza with various shops, cafés, waiting rooms, interview halls, and small offices. These systems can be used in conjunction with other systems to serve a larger area. It is economical with each system being self-contained. This means that if one unit breaks down, the entire system is not affected. The only downside is that you need enough external space to setup the outdoor units for each indoor unit.

A standard AC installation includes: examining duct wires and refrigerant lines, using a gravel base to level out an area for the new AC,removing existing indoor evaporator coils, mounting and installing indoor units on the wall, placing and installing outdoor units at reachable locations, setting new air conditioner condenser,drilling minimal holes for connections (the wall core is not cut in the process) and lastly the cleanup and closing to remove any drilling debris and equipment from the installation site. Some providers also perform a test run to check functionality and add a locking cap tothe outdoor unit to prevent theft of the refrigerant.

Yes. You can install the AC unit yourself. However, you will need a specific set of tools and some experience with hardware. Depending on the type of AC unit each installation will be different. Overall, self-installation is possible with a ladder, drill, nails, and the right safety equipment. It has the perks of developing new abilities, saving initial installation costs, and the freedom to explore your AC’s hardware but also has the disadvantage of manual labor, violation of warranty, and long hours of effort. If you choose to replace an old AC with a new one, you may also need a special certification to do so.

To figure out how big an air conditioner you'll need for a room, multiply the room's length by its width. Then multiply that by 25 BTU to achieve a sufficient amount of cooling for the room in all weather conditions.AC size is determined in terms of weight. i.e., tons. The larger the area, the heavier will be the AC’s compressor. For example, a 600-1000 square feet area needs a 1.5-tons air conditioner, 100-1500 square feet, a 2-tons AC, 1500-2000 square feet, a 3-tons AC, and 2000-2500 square feet, a 4-tons AC respectively.

This depends on the condition of your AC. If it’s a small problem that you have identified early on, then repairing is better than replacement as it is less expensive and saves the trouble of new purchase, dismounting, reinstalling, and labor cost.If the filters and coils are cleaned regularly, then you can also save on expensive maintenance and part repairs. However, if your AC is constantly breaking down, never cooling the home properly, operating very loudly, or inviting contaminants into the indoor air, then repair may be more expensive and strenuous. In this case, replacing the damaged unit is better than investing in it.

The most common problem is a frozen evaporator coil. This problem occurs when the AC doesn’t receive enough air to function properly. The frozen coil, in turn, can jam the AC and stop it from working or invite contaminants into the indoor air. This problem can occur due to many reasons including blocked ducts, vents, dirty air filters, and faulty fans which prevent enough sit from reaching the evaporator coil. The coil is up and eventually freezes. The best way to prevent this issue is to maintain a clean filter, to allow maximum airflow into the AC’s hardware.

If you provide proper maintenance to the AC unit, it can last a surprisingly long time. You can expect your AC lifespan to be anywhere between 10-and 15 years unless you experience repeated problems with the unit. To ensure a long life, make sure to clear the filters periodically and ensure proper storage. Look out for the following signs to see if a repair is needed. Your AC isn’t giving off enough cool air, the airflow isn’t as strong as usual and the entire room isn’t cooling up, you notice moisture and leakage around the unit, and when you hear an unusual sound coming from the AC

The most common cause of a furnace malfunction is the dirty or clogged filter which reduces air intake and lowers heating efficiency. Besides the filter, some other issues can be thermostat malware which is indicated by a continuously running fan, weak or flickering pilot lights that indicate excessive carbon monoxide built up, damaged heat exchanger is a costly problem which can be due to overheating, frayed blower belt which will block the fan from running smoothly, over cycling if you run your furnace too high for too long, and rattling, pinging and popping sounds related to lose panels and required duct maintenance.

If you turn on the furnace but no heat comes out, there could be a blockage. Dust and grime obstruct airflow, and if the filter becomes too clogged, the heat exchanger can overheat and shut down prematurely, preventing your home from warming up. If the surface of the furnace filter is covered with impurities, you should clean it out, and if it is too damaged, consider replacing it. Aside from connections, improper thermostat settings can also confuse your furnace. Make sure your thermostat is set to ‘heat settings’ as raising the temperature of the heating isn’t enough.

There can be more than one reason for a heater not heating your home. A common cause is extremely dirty filters which can block the airflow leading to obstruction of pipes. Also, you may not realize that your heater may have an additional switch button for safety reasons, make sure it is ON. It is also possible that the electricity supply to the heater is cut off due to a faulty breaker. Do inspect your thermostat, if it is not set on ‘auto’ or ‘heat settings, or if the temperature is too low, then the heat won’t turn on.

This depends on how frequently you use your AC and how old it is. New units are usually stronger and will not suffer damage even if maintenance is delayed. However, for older units with roughened parts, maintenance plays an important role in keeping the unit running. However; generally, you should have your air conditioner serviced twice every year. It's best to do so right before the seasons change, once in fall and once in spring. Moreover, you should also clean the filters periodically and check the coils and fins for any clogging. Doing so is a good way to keep your AC in top shape and for safety as well.

AC maintenance requires both self-inspection and periodic inspection by professional repair mechanics. There are some early-stage tips to maintain your AC in good shape and prevent any expensive damage. For example, cleaning your filter every week and changing it once a month, keeping the coils clean, inspecting the fins to see if they are running smoothly, and inspecting the drain for any clogging. Lastly, a professional scheduled inspection for the AC unit at least once every year (twice a year is recommended) is mandatory to prolong the life of your AC unit and save money in the long run.

It is recommended that you service your AC twice every year. The best time is before a season changes, i.e., once before fall and once before spring. While it is a good idea to check for any damage yourself periodically and keep the filters and coils clean, this isn’t enough for a proper survey of the system. Therefore, professional maintenance every once a year is mandatory to make sure that the AC unit functions smoothly. If you opt out of maintenance, to save a few bucks, you will have to pay a larger sum to replace the AC unit, as without maintenance it will break down and go beyond repair.
