Exactly what does it mean when an HVAC system is inspected?

Homeowners, landlords, and business owners all know how important regular upkeep is for a building’s continued viability. Your heating, ventilation, and air conditioning, as well as the rest of your mechanical components, are no exception. To keep your systems in top shape and head off any issues before they escalate, inspections should be performed on a regular basis.

Now, let’s talk about what exactly an HVAC audit is. An HVAC audit is a comprehensive check of the heating, ventilation, and air conditioning system. The HVAC inspection is carried out by a qualified specialist to ensure that the system is operating as it should and that all of its parts are clean and free of any potential hazards. The technician will check the system’s age and general health to make sure it’s in good operating order.

As part of an HVAC audit, a professional will look at your heating and cooling systems to determine how well they are functioning. In addition, experts will have to use specialized equipment to check the system’s functionality. You will be provided with a report after the inspection that specifies any issues or shortcomings. If the unit is not in working order, the Tech will outline what has to be done to get it back in working order. Not inspecting and maintaining your HVAC system may lead to premature failure, which can be quite expensive to fix.

Maintenance of your heating, ventilation, and air conditioning system should not be neglected. Preventing the need for expensive repairs in the middle of the season by keeping up with routine maintenance and inspections of your HVAC system is a wise investment.

How much does it typically cost for an HVAC technician to check everything out?

The industry name for all HVAC systems is “HVAC.” While the acronym HVAC refers to Heating, Ventilation, and Air Conditioning, not all HVAC systems have either warming or temperature control. An HVAC inspection’s price tag might fluctuate depending on a number of factors, including the system’s age, make/model, size, and general condition. The average price of an inspection is $300. The inspection and maintenance costs of a heating-only HVAC unit are lower than those of a system including climate control. Water-based heating and cooling systems, such as boilers and chillers, may be quite expensive if they are complex.

During an HVAC audit, what should be looked at?

All of the main and small parts of the HVAC system should be double-checked throughout the inspection to guarantee smooth functioning. The implementation plan is a valuable resource for anybody responsible for doing the HVAC check.

There is a leak in the flexible pipe, and the conditioned air is leaking into an empty room.

The HVAC inspection should also consist of checking the ductwork for any leaks, rips, or cracks, since these may seriously impair the efficiency of your system. A well-operating HVAC system requires efficient heat transmission. Air is used more than any other medium to disperse heat. The accompanying shot clearly demonstrates that the ducting has separated in the center, enabling the conditioned air to escape into the attic. The unit will have to operate more often, using more energy, and having a shorter lifespan as a result.

Even during an HVAC audit, make sure the airflow intakes, air fresheners, and enclosures are open and not destroyed so that the conditioned air can flow to where it is needed.


Maintenance: Air Filter Changeout

Filters are essential for maintaining healthy indoor air quality and reducing allergens and other pollutants in the air. They shield the HVAC system from damage caused by dust and debris by screening out contaminants before they can clog the air coil, collect on the fan wheel, or make their way into the ducts. Changing the air filter on a regular basis will keep the unit from being deprived of the oxygen it needs to function properly. Much more costly fixes may be necessary if the filter is clogged with debris.


All filters should not be seen as equivalent. Several alternative MERV classifications are offered for either domestic or industrial use. More airborne particles are eliminated with increasing MERV grades. Before raising the MERV rating of your filters, check with your HVAC technician to be sure your system can manage the reduced airflow.

How well maintained and clean are the fan and its blower wheel are

It is necessary to clean the distribution system through even HEPA filters to let some particles across (albeit not much). When the centrifugal fan wheel on your unit becomes dirty, it can no longer move as much air. As a result, the fan wheel may easily become unbalanced if dust and debris are not cleaned off in a timely manner. This might lead the motor bearings to wear out sooner than expected, leading to louder fans and the need for expensive major repairs. A wheel that isn’t balanced correctly is subjected to unnecessary strain. See how the hub weld on this fan wheel failed in the accompanying shot. The fan may last longer if the wheel is kept clean.

Heat exchanger and condensing coils’ level of wear and tear

Heat or “cooling” is transferred to the air via the use of condenser and evaporator coils. The Heat transmission is impaired at either the interior or outdoor air coil if the coil is filthy.

The result is a rise in energy use and the possibility of malfunctioning or even broken parts, such as the compressor, due to this. A well-functioning HVAC system depends on these parts being kept clean, unobstructed, and undamaged.

The gas furnace’s heat exchanger

Oil, propane, or natural gas may fuel gas furnaces. They use a method of indirect combustion to generate heat. Combustion produces toxic byproducts, such as carbon monoxide (CO).

The flue pipe, or “chimney,” is used to vent this gas outside of the building. During the HVAC examination, cracks or holes in the heat exchanger should be looked for.
