One can hardly imagine life without the existence of HVAC systems that offer a great degree of comfort and a good quality of air in homes and offices. However, just like any complex mechanical construct, HVAC units can experience issues over time.
This article is about the common HVAC problems, some step-by-step causes, how to choose HVAC system service options, and when to hire a professional.
Understanding Common HVAC Problems
HVAC problems often require assistance from professional technicians, like those at Chill Heating & Cooling – HVAC Company. A system of HVAC consists of different components that should interact with one another, such as thermostats, ducts, coils, compressors, blowers, filters, etc. The failure or poor performance of some parts can affect the system.
Bad maintenance, wear and tear, or even indiscriminate human error can usually cause problems. By diagnosing the trouble beforehand, you might not cause more damage to your system, and also can lengthen the lifespan of the system.
Top 5 Common HVAC Problems and Their Symptoms
This is the list of the most common HVAC problems, and the symptoms for home systems and an HVAC system for business.
1. Clogged and Nasty Filtration Systems
With clogged air filters, the flow of air is hampered, and your system has to strain more in cooling its users because of the reduced efficiency and performance.
2. Thermostat Malfunctions
Weak response of the system to the temperature levels may be a problem of the thermostat, particularly when it is an old or batteryless one.
3. Refrigerant Leaks
The issue of low levels of refrigerants also indicates a leak. Your space cannot be cooled in the right manner without enough refrigerant.
4. Problems with Pilot Light or Ignition of Household
The problems in ignition of the gas or the pilot light can prevent the furnace from generating any heat, and this can occur due to the buildup of dust, wear, or broken parts.
5. Drainage Problems
Liquid in the condensate drain line can also accumulate algae or debris, leading to a leaking condensate drain, and, in the other possible case, condense the system as a precaution.
Step-by-Step Troubleshooting Guide
Technical troubleshooting can be done without the assistance of a technician, as most of the HVAC issues can be resolved by simple steps:
Step 1: Thermostat Check
- Make sure that it is in the right mode (warm-cold).
- Change batteries where needed.
- Make sure that the temperature is right.
Step 2: Check the Air Filter
- Locate the filter.
- In case it is dirty or clogged, remove it and put on a new one.
- Monitor filters every month and, depending on need, change approximately every 1-3 months.
Step 3: Testing Circuit Breaker
- Make sure that the electrical panel is ok when the system will not come on.
- Search tripped breakers and reset them where necessary.
- In case it trips several times, there might be an electrical problem that needs professional assistance.
Step 4: Blocked Vent and Registers
- Visually inspect (or ask the occupant to) locate blockages at vents and registers.
- Make sure nothing is in front of the air vents, such as furniture and drapes.
- Locate every opening in the bike room and make it easy to enter air into the room.
Step 5: Remove Obstructions in the Condensate Drain Line
- Find the location of the drain line and test for visual blockages.
- Clearing out clogs can be done through the wet/dry vacuum.
- Pour a cup of white vinegar into the line to deter the growth of algae.
Step 6: Check the presence of Ice or Frost on the Coils
- In case of frozen coils, switch off the unit and allow it to thaw.
- Possible causes to be checked include dirty filters or low refrigerant.
- Do not ever make an attempt to add refrigerant yourself; this is the work of a licensed technician.
Preventive Maintenance Tips
30-50% of businesses are using HVAC systems as a short-term solution for poor indoor air quality. The following are some of the few things you can do to maintain your system, improve indoor air, and reduce HVAC operating costs:
- Make Regular Checkups
- Change Filters
- Clean around the Outdoor Unit
- Look out for Unusual noises or smells
- Keep Vents Open and Clear
- Have a Programmable Thermostat
Such measures will minimize the chances of a breakdown, enhance the quality of indoor air, and save money on energy bills in the long term.
When to Call a Professional
Although a great number of HVAC problems can be resolved through standard troubleshooting, there are also cases when you must choose HVAC system techs who are licensed, such as those at Chill Services. They are needed for problems such as:
- Leaks
- Electrical or Wiring Problems
- Continuous Sounds or Smells
- Short-Cycling
- Installation or Replacement of System
Do not wait too long to find help- if there are issues with HVAC, when it is neglected, more significant damage and expensive repairs can occur, which could be detrimental to a HVAC system for business.
Conclusion
HVAC is vital to any provisions made to keep comfort in your house or your business, but it is not spared from problems. Understanding the prevalent HVAC problems along with the means of their solution may spare you a considerable amount of time, financial expenses, and inconveniences.
With an HVAC in good shape, you will benefit from having a well-functioning unit that will provide you with several years of service, making your space comfortable no matter the season.
