Hello World! Welcome Friends! HVAC (Heating, Ventilation, & Air Conditioning) systems can be considered a necessity. This is considering the need to have good and comfortable indoor air quality. Overall, well-functioning HVAC systems are important for reasons that include the following:
- Guaranteed Health & Safety Indoors
- Longevity for the System
- Humidity Control
- Consistent Temperature Control
- Productivity for Occupants
- Positive Environmental Impact
- Increase in Property Value
- Reduction in Repair Cost
These are just some of the reasons why a properly functioning HVAC system is important. For more on this subject, you can visit: https://storables.com/.
Against this backdrop, people need to know when to reach out to HVAC technicians. This is also important given how quick intervention whenever required can de-escalate complications. To this end, this article discusses some common issues that require the expertise of these contractors.
HVAC Repairs Best Left to a Professional Contractor
Some users try fixing some issues on their own. Well, there are certainly some minor issues that can be self-handled. Prime examples include:
- Thermostat Resetting
- Air Filter Replacement
- Replacement of Thermostat Batteries
- Air Duct Inspection & Cleaning
- Air Vent Adjustment
- Inspection of Circuit Breaker
These and a few others fall under the category of issues that may be resolved without professional expertise. However, some lines should never be crossed with these systems and unprofessional handling of more complex issues is one such.
There are many downsides associated with the failure to heed this warning. Bearing this in mind, some of the common issues that should only be handled by HVAC contractors include:
1. Refrigerant Leaks
There are two common indications that this is the problem. It is either there is a buildup of ice on the system’s evaporator coils or a poor job at effectively cooling the indoor space. This is especially true when there is a significant drop in performance.
The expert approach to resolving the issue first requires identifying the point of leakage. Repairs are thereafter carried out before a recharge is done.
The toxic nature of refrigerants is one of the major reasons HVAC contractors should only handle such tasks. So, self-repair is a no-no, regardless of how handy you are.
2. Electrical Problems
Several signs could suggest that the problem with your system is electrical. This includes signs like:
- Premature shutting off
- Failure to come up
- Failure to maintain the specific temperature that has been set
As with almost every other issue, the expert resolution starts with a diagnosis of the problem through extensive inspection. Thereafter, active repairs, such as fixing faulty capacitors, relays, and wiring are carried out.

3. Frozen Evaporator Coils
The evaporator coils play very important roles. Problems with them can lead to any or even many of a wide range of downsides, including:
- Poor Heat Exchange – Especially due to poor heat absorption
- Increased Operational Cost – Due to energy inefficiency
- Uneven Cooling
- Humidity Concerns
- System Breakdown
Against this backdrop, frozen evaporator coils are usually a sign that something is wrong. Refrigerant leakage is one of the possibilities and a common one at that. However, it could be a result of several other things, including:
- Low Refrigerant Levels – Leading to a significant drop in temperature and then freezing of this component
- Restricted Airflow – Caused by issues like dirty air filters, issues with the blower motor, and closed or even blocked vents
- Oversized System – The indoor space is supposed to inform the size of the HVAC system used. Frozen evaporator coils are possibilities when the system used is too much for the space in question
- Drainage Issues
Overall, only professionals are supposed to diagnose and resolve this issue. So, you should not attempt self-handling as you can even make things worse.
4. Unusual Noises
The presence of loose or even damaged parts is often the reason for unusual noises. This could be parts like belts, bearings, or even motors; resulting in clanking, squealing, or banging sounds.
HVAC contractors should be contacted to identify the mechanical problem responsible for the unusual noise and then fix it. This is instead of untrained and inexperienced people trying to address the issue themselves.
By the way, prompt contact with an HVAC expert is required when such noises are noticed. This is because things can get out of hand the longer the issue stays unresolved.
Wrap Up
Being a responsible user of HVAC systems requires knowing how to address some issues. However, there are boundaries, which is why you need to know issues that you should never attempt to resolve on your own. Rather, contact should be made with an HVAC contractor.
This article has gone on to explain some of such issues and common ones. You can see Mainard & Sanders Heating and Air Conditioning for more on issues that should only be expertly handled. By the way, a good working relationship with these experts also ensures that you know how to keep your system in the right state.
On a final note, these experts play a key role in ensuring your indoor convenience. As a result, you should do all to hire very capable professionals in this line of work.
