HVAC MAINTENANCE NYC

Our commercial HVAC company in also offers specific commercial heating maintenance programs in NYC – designed to keep your heating unit running strong during our cold New York winters.

Inspect and replace HVAC air filters

The single most important part of maintaining you HVAC equipment is to regularly change your air filters. A clogged and dirty air filter not only blocks normal airflow, but reduces your unit’s efficiency while raising your energy bill. Regularly replacing air filters can reduce energy consumption by 5% to 15%. The obstructed air flow places an additional strain on the unit, causing the unit to go into over drive. Replacing the air filters also increases the quality of air flow in the space. A dirty air filter can turn into a health hazard for those with COPD, allergies or asthma.

Clean blower assembly of normal dirt

Did you know that dirt gets stuck inside the fins of the squirrel cage which prevents the blower from pulling a sufficient amount of air? When the blower wheel doesn’t pull enough air the unit keeps running without the space temperature getting satisfied, which leads to much higher energy consumption, and reduced air flow.

Inspect all belts and replace as needed

Like HVAC filters, belts are a critical part of HVAC maintenance. It’s very common for a belt to be misaligned due to the vibration of the unit. If a belt is misaligned and loosens up, there will be a substantial loss of torque and can wear down the pulley wheel. Why pay thousands of dollars in repairs when the simple act of adjusting or replacing a belt will not only save money, but extend the life of your unit.

Lubricate all fans and motor bearings

All moving parts in your HVAC system require regular lubrication to prevent friction in parts such as a motor. Increased friction leads to the parts working harder increasing energy use while also wearing down the part.

Inspect the refrigerant operating pressures & visually check for refrigerant leaks

Maintaining a consistent level of refrigerant is the key to proper operation of any HVAC system. If a system is missing refrigerant while the unit is running, the compressor will get damaged which costs a lot to repair. A lack of refrigerant can cause a system failure in 2 ways. The first is that the low pressures will cause the compressor to freeze up. The other form of failure is simply due to the fact that the compressor requires a certain amount of refrigerant to run properly.

Inspect condensate pump, drain pan, clean out drain lines using CO2, & Supply pan with acid tablets

Most HVAC service calls we receive are for leaking Air Conditioning units. The main reason a unit leaks is due to a clogged drain line. A professional HVAC contractor will put acid tablets in your drain pan to help reduce the future buildup of dirt,soot, & mold. Don’t let something as simple as standard HVAC maintenance be the reason your ceiling comes caving down due to a water leak. Prevent these issues before they occur.

Check & tighten electrical connections

Why spend $350 on a burnt out contact when you could have prevented the issue during preventive maintenance? Lots of electrical parts burn due to loose connections. We also come across plenty of service calls that had units shut off because the electrical connection in the thermostat was loose. Prevent this issues today with performing maintenance the right way.

Calibrating safety controls and temperature controls

We go to hundreds of service calls a year because office buildings & retail stores don’t get the control settings checked. One wrong setting can leave your hanging in the 100 degree heat. Controls should be checked & calibrated at least twice a year to prevent HVAC breakdowns.

Take ampere readings on all motors and compressors

If a compressor or motor is on its way out, would you rather take preventive measures and get it replaced before the summer season, or would you rather wait for the heat wave to hit? Businesses fail to understand that being proactive is much cheaper then being reactive. Why wait until customers wont shop due to heat?

Inspect and adjust valves and dampers

Before heating season, it makes perfect sense to close all the gas valves as a safety precaution. What happens when the winter comes and all the sudden your heating system doesn’t turn on? A good AC maintenance company would inspect and adjust all valves & dampers. They should adjust according to seasons and desired conditions.

Inspect Supply & Return Temperature

The best way to assure a client that an HVAC unit is operating correctly is to show the temperature difference between the air being sucked in versus the cold air being distributed.

Inspect & Clean Evaporator & Condenser Coils.

Both your evaporator & condenser coils are a key component of any AC system. When they are cleaned, your HVAC system will operate at peak efficiency. However, when your coils are dirty, they can cause many problems including:

Increased Operating Costs: When your coil become dirty it cannot provide adequate or designed heat transfer which will cause higher discharge pressure. This will require more electricity, which translates into increased utility costs. In fact, dirty coils can increase energy consumption 37% over clean coils.

Reduced Cooling: As the dirt collect on the coils it restricts heat transfer causing the compressor to work harder. This adds more heat to the system and raises the head pressure as much as 75% which can result in a loss of up to 30% of the systems cooling capacity. This loss is most noticed on the hottest days when cooling is needed the most.

Shorten Equipment Life: Higher operating pressures and temperatures caused by dirty coils can reduce the equipment’s life expectancy. The higher system pressure and temperature can lead to the breakdown of the compressors lubricant. In addition acid can occur, leading to an acid burnout. This will lead to equipment failure. Compressor failure means no cooling, and costly repairs.

Affect Air Quality: The evaporator coil presents major issues that go way beyond the issues we previously discussed. A dirty evaporator coil creates a breeding ground for bacteria and mold that can impact the indoor air quality.
