HVAC Inspect, Troubleshooting and Repair

HVAC Inspect, Troubleshooting and Repair

No matter when your HVAC system fails, it will cause discomfort to the kitchen staff and disrupt business. If you have outfitted your commercial kitchen with an HVAC system, you should get a timely inspection and quickly troubleshoot issues so that repair can be affordable. Ignoring or delaying repairs of the system can lead to costly repairs later. Worse still, you may need to replace the entire unit with a new one for proper indoor quality, health, and safety. Always seek the services of professionals to maintain your HVAC system in an effective manner. Outages happen mainly due to a lack of maintenance. Therefore, it is key to understand the importance of regular maintenance.

What is HVAC?

An HVAC or Heating, Ventilation, and Air Condition system is installed to heat or cool a building or facility. It keeps the space cool during summers and warm during winters. Key components of the system include an A/C unit, heat pump, furnace, etc. The main purpose of designing and installing such a system is to comply with the environmental requirements for the comfort of people. You’ll find the usage of HVAC systems in a wide range of facilities including industrial, commercial, and residential.

HVAC Inspection

Once you have outfitted your commercial kitchen or restaurant with a high quality HVAC system, it should be your top priority to keep it operational at all times. No matter what time of the year it is, the heating, ventilation, and air conditioning system should work properly to meet your facility’s comfort needs. Regular inspection is a surefire way to maintain a proper HVAC system. At the APS Hoods, we provide HVAC inspection by highly experienced professionals. The HVAC inspection procedure consists of multiple steps. Each step should be carried out in a correct and safe manner by experienced professionals while adhering to all the necessary safety guidelines.

Run a Thermostat Test:

The system inspection begins with a thermostat test in which the HVAC technician finds out whether it is working in an efficient manner. The technician checks whether the heating and cooling mechanisms have any issues when turned on and turned off.

Inspect Air Filters:

The function of HVAC air filters is to purify the air of impurities such as dust, dander, pollen, etc. The inspection finds out whether the air filters are in good condition to properly purify the air. 

Evaluate Air Flow:

Measuring the airflow through the HVAC ducts and equipment is an important step in the overall inspection process. If the airflow is not proper, the system will not heat and cool the facility in an efficient manner. So, the technician finds out whether the airflow rate is at a typical level.

Check Refrigerant Level:

Low refrigerant level prolongs the time taken for the HVAC system to cool off the space. Ultimately, it leads to high energy consumption. During the inspection, the technician checks whether the refrigerant level is optimum for the AC unit to function properly.

Check Heater/ Furnace:

It is crucial to inspect if the heater or the furnace is working with maximum efficiency. In order to do that, the HVAC technician turns on the heating element and then measures the temperature of the air. Insufficient heating means the heating element has an issue. 

Check the Blower Motor:

The blower motor is a crucial component of every HVAC system. If it does not operate properly, the system will not give the desired results. The technician will inspect the motor and find out if it has any issues. Loud or unusual noises coming from the motor mean there is something wrong. There are many other warning signs of a faulty HVAC motor as well.

Other Components:

In addition to these, there are multiple other components that need to be inspected. The HVAC technician will conduct an inspection of each and every part of the system including the condenser, evaporation coil, and all the electrical parts as well as the compressor. During the inspection, the HVAC technician will also level the unit and clean the filters as well as the evaporator coil. The goal of the inspection is to find out the overall efficiency of all the units of the HVAC system. Once the job is done, the technician will prepare a detailed report of the inspection for your understanding. If the HVAC system or any of its components has a problem, a proper inspection will bring it to light so that you can get the maintenance or required repair. If you plan for a professional inspection of your facility’s HVAC system, reach out to one of our highly experienced technicians at the APS Hoods in Denver, Colorado.

HVAC Troubleshooting

The goal of troubleshooting is to identify and solve issues. If you plan to quickly fix the problems with your restaurant’s HVAC system, you need to get troubleshooting done by highly skilled technicians. At the APS Hoods, our professionals perform troubleshooting of a wide range of HVAC systems and diagnose and establish a plan of action to fix the problems in a professional manner. HVAC troubleshooting by an expert involves the identification of a problem, diagnosing the problem correctly, and then developing and implementing a plan of action, and then verifying the system for functionality. Most of all, the technician documents every detail of the entire procedure for your record. In order to diagnose problems with the HVAC system, technicians first begin with the visible components and then work their way to the inner parts of the system. So, the HVAC technician will first troubleshoot whether the system has power. Next, the specialist will move on to the service panel and see if the circuit breaker has tripped or not.  The heater or the furnace and the A/C unit each have their own circuit breaker or fuse. If the fuse has tripped, broken, or blown, the troubleshooting will reveal the fault for the removal or replacement of the circuit breaker. The next step in HVAC troubleshooting is to check the thermostat for power. The HVAC troubleshooting involves checking the furnace, the air conditioner, and the ventilation units. Experienced technicians employ a wide variety of techniques and tools to carry out the troubleshooting in a proper manner. The technician checks the HVAC air conditioning unit for air filters circuit breakers, vents, outages etc. The outside A/C unit is also checked during the process. At the APS Hoods, we have an expert team of highly qualified, trained, and experienced technicians for professional troubleshooting of all sizes and models of HVAC systems.

HVAC Repair

It is not uncommon for HVAC systems to develop various kinds of issues over time. Most minor issues will go away with maintenance and cleaning of the coils and the filters. Regular servicing and preventive maintenance are key to avoiding a number of HVAC issues. Other problems will require immediate attention from the facility manager or the owner of the restaurant.  What is important is that you keep a close watch on the performance of your facility’s HVAC system. As soon as you spot any problem with the system, you should call inexperienced HVAC technicians. Key signs that you need HVAC repair include:

Change in Airflow:

If there is a change in the airflow of your HVAC system, it will not cool off in an effective manner. Slower than normal airflow takes its toll on the efficiency of the system and the A/C unit does not get as cold as it used to be. This can be an indication of a problem with the compressor. So, you should get in touch with an HVAC technician for the required repair.

High Energy Bill:

A steady monthly bill means your HVAC system is functioning in a proper manner. But if the bill amount continues to increase month after month, this is a warning sign. If there is something potentially wrong with the system, the consumption of energy will be higher. It usually happens with the change in season. Fluctuations in the energy bill should be taken as a warning sign and you should immediately seek the help of professionals to get repairs done.

Old Age:

Different kinds of problems will arise as your HVAC system gets older. Every type and model of HVAC has a certain lifespan. Once it passes that period, you should expect to see problems. While regular preventive maintenance can prolong the lifespan by a couple of years, it can not fully restore the previous efficiency level. Either the problems will go away with repairs or you will ultimately need to replace your old HVAC system with a new one.

Noises and Smells:

If your HVAC system makes unusual sounds, it is a sign there is something wrong. Not just sounds, but the machinery also begins to give off smells like that of dirty socks. Noises and smells coming from the system mean you need repair services as soon as possible.

Moisture or Dust Buildup:

Excessive deposits of moisture or dust in your commercial kitchen or restaurant facility signal a problem with the HVAC system. Such problems will possibly require the cleaning of the entire system, vent hood cleaning, and duct cleaning. The technician will find out and fix if there are other problems that lead to the excessive dust buildup.

Power Failure:

A sudden power failure of the HVAC system is a potential sign there is a problem. If the heating, ventilation, and air conditioning equipment gets turned off or the circuit breakers trip frequently, you should call in HVAC specialists to troubleshoot and carry out the necessary repairs. If you ignore these signs, it can take a toll on the electrical components of the system. Seeking the help of professionals for timely repairs will save you both money and time. At the APS Hoods, we have an expertly trained team of professional technicians to carry out all kinds of HVAC repairs. Getting the repairs done without any delay will help you run your restaurant business smoothly as well as avoid damage to other components of the HVAC system.

    HVAC System: Summer is a Perfect Time for Adjusting by APS Hoods

    Image Source Denver, CO – While commercial kitchens always run hotter than dining areas, in the summertime–restaurant kitchens become can become hazardously hot. Furthermore, restaurant owners find that their energy bills–from cooling, fan use, and unbalanced air, etc.–increase dramatically. This ends up leeching resources from their profits. It also makes summer an ideal time to fine-tune and check your commercial kitchen HVAC system professionally. Here are some common problems that may be plaguing your restaurant in the warmer months:

    Cool Air Is Pulled Out Through Exhaust Fan

    Is your air conditioning bill incredibly high, while your establishment always seems inadequately cool? What may be happening is that your cold, conditioned air is being circulated out of your exhaust hood due to a lack of make-up air. Instead of just doing its job of pulling gasses and hot air from above the stove, the exhaust hood can sometimes suck out the desirable air from inside your building. This often creates a vacuum effect in your entire restaurant, where it becomes difficult to open doors without them slamming you upon closing. The solution to this problem is as simple as installing a makeup-air unit. This kind of unit in your kitchen will generate much needed negative air pressure that will disallow unpleasant smells from flowing out into your general building, while also not letting your air-conditioned air to so easily escaping through the vents.

    Grease Filters Making Your Ventilation Ineffective

    Spring, and especially summer, tend to be the busiest and most profitable month for any restaurant. People are out and about on the town, looking for new eateries to discover.  This brings many more people to your establishment than during the harsher seasons of the year. However, the increased amount of cooking also results in clogged grease traps, which may need to be changed out more often than recommended. Clogged grease filters can cause your kitchen to overheat. Then, your air will become unclean, as a dirty filter cannot function at top capacity. This will cause both the kitchen and dining area to become smoky or otherwise unpleasant in odor. Moreover, your air conditioning bill will rise ever higher, while your exhaust fan will need to work harder to compensate for all these issues. This makes for employee health dangers, customer discomfort/dissatisfaction, and higher bills for you! It is easy for even the most disciplined restaurant crew to forget to monitor their grease filters, but it is necessary to keep tabs on the situation to maintain the optimal function of your HVAC system. It is smart to schedule routine filter changes throughout the Spring and Summer when business really picks up.

      Makeup Air and The Importance in Commercial Kitchens | Denver, CO

      Image Source Denver, CO – The same exhaust fans that are keeping your commercial kitchen comfortable and protecting the area from overheating may also be creating air imbalance problems throughout your establishment. Because the size, design, door, and window placement of every building varies, the mechanism by which the atmosphere of your restaurant can best be corrected is most accurately established by an HVAC professional. They can provide what is called a Makeup Air service, which essentially replaces the air lost through hood fans with a special unit, which avoids some of the problems which present themselves when air from other areas of the home or building replace that lost air.

      Call APS-Hoods for a free estimate on your Commercial Kitchen Hood Cleaning & Kitchen Exhaust Cleaning needs.

      Negative Air Pressure

      If the exhaust fan was not installed/incorrectly installed, or simply, if the makeup air from the fans is not enough to replace the air exiting from the stove area, negative air pressure can occur. Negative air pressure creates a sort of vacuum in your space, where windows and doors can shut suddenly, dust particles can settle fast onto surfaces or food, and whistle-like noises can also persist when air is let out or into space. These are very undesirable conditions for a dining or cooking area because of hygiene reasons as well as the disruption of ambiance this can create.

      Draft-back

      With negative air pressure sucking everything back into your space, the gasses that are supposed to be going out from your chimney will actually come back in, creating a health hazard. This can set off carbon monoxide detectors and threaten the safety of your patrons and employees.

      Inefficiencies in Hoods

      The exhaust hood, unaided by the sufficient amount of make-up air, will–in turn–not be able to process the amount of air it was designed to handle. Over time, you will notice a buildup of grease and grime on your kitchen surfaces. Also, unpleasant cooking and other smells will seep into all the space pockets of your building, including the dining areas, where patrons are trying to enjoy their food!

      Higher Energy Expenditures

      Insufficient replacement air in your kitchen will encourage the air from outside to be absorbed inside. This ends up throwing the heating and cooling conditions out of balance when your heater or air conditioner tries to counteract the problem. Your establishment will probably run too hot or too cold at all times, causing freezing or condensation and never really achieving a comfortable state. You, as the restaurant owner will only get a higher energy bill and a big headache trying to figure a way to finally stop this air imbalance problem. However, the problem is one for the professionals with a good diagnostic system that needs to be applied in a customized manner to every restaurant space with the care each one deserves.
