Texans from the Rose Capital often learn from professionals performing HVAC services in Tyler, TX how routine tune-ups can help identify efficiency issues before they impact daily comfort. This insight allows homeowners to plan maintenance proactively and avoid sudden system failures.

It’s advisable to have professional HVAC technicians perform these inspections at least twice a year.

• Spring and Fall Check-Ups: Schedule maintenance before the onset of extreme weather. Spring and fall are ideal times for these inspections to prepare for the upcoming heating and cooling seasons.
• Filter Replacement: Regularly replacing or cleaning filters can significantly enhance the efficiency of the system. Dirty filters restrict airflow, making the system work harder and consume more energy.

2. Regularly Clean and Replace Air Filters

Clean and replace your HVAC’s air filters so you’ll be sure the air you breathe is clean and free of contaminants such as dust and pollen. A clean filter also helps reduce the energy consumption of your HVAC unit. 

3. Make Sure the System is Calibrated Properly

Your HVAC should be calibrated regularly so the thermostat and controls function optimally. The process is crucial for energy efficiency and should be handled by professionals.

• Programmable Thermostats: Upgrade to programmable or smart thermostats if you haven’t already. These devices can optimize HVAC operation based on occupancy schedules, significantly reducing energy consumption.
• Calibration: Ensure that thermostats are correctly calibrated. Inaccurate thermostats can cause the system to run longer than necessary, increasing energy usage and wear.

4. Maintain a Clean and Debris-free HVAC System

Clean the HVAC system’s components and keep the surrounding area clear of debris. These steps will prolong the unit’s lifespan and make it more efficient.

Additionally, regular maintenance helps your HVAC maintain good air quality and ensures you meet warranty requirements, which ultimately saves you money, such as Technical Hot & Cold Parts, which offer OEM brands at competitive prices.

The coils in your HVAC system play a crucial role in heat exchange. Over time, coils can accumulate dirt and debris, which can reduce their efficiency.

• Evaporator Coils: Located inside the unit, these should be checked and cleaned at least once a year. Dirty evaporator coils reduce the system’s ability to absorb heat.
• Condenser Coils: Located outside the building, condenser coils should be inspected and cleaned more frequently due to exposure to the elements. Ensure that the area around the condenser unit is clear of debris, vegetation, and other obstructions.

5. Plan Preventive HVAC Maintenance

A preventative maintenance plan includes regular inspections and immediate repair of minor issues to avoid unexpected failures. You can have an annual or bi-annual maintenance schedule if you already work with a trusted air conditioning technician.

• Scheduled Maintenance: Develop and adhere to a maintenance schedule that includes all the critical components of the HVAC system.
• Documentation: Keep detailed records of all maintenance activities, repairs, and replacements. This can help in identifying recurring issues and planning future maintenance activities.

6. Inspect and Seal Ductwork

Leaky ductwork can lead to substantial energy losses as conditioned air escapes before reaching its intended destination.

• Sealing and Insulation: Seal any leaks with appropriate materials and consider insulating ductwork in unconditioned spaces to prevent energy loss.
• Duct Inspection: Have a professional inspect the ductwork for leaks, gaps, and blockages. Common areas for leaks include joints and connections.

7. Monitor and Maintain Refrigerant Levels

Refrigerant is essential for the cooling process in HVAC systems. Low refrigerant levels can cause the system to operate inefficiently and may lead to component damage.

• Leak Detection: Regularly check for refrigerant leaks. If the system is low on refrigerant, it typically indicates a leak, as refrigerant does not evaporate.
• Recharging: Ensure that refrigerant levels are at the manufacturer-recommended levels. Only certified professionals should handle refrigerants due to environmental regulations and safety concerns.

8. Ensure Proper Airflow

Unobstructed airflow is critical for the efficient operation of HVAC systems.

• Vents and Registers: Make sure that vents and registers are not blocked by furniture, curtains, or other objects.
• Air Handler Maintenance: Regularly inspect and clean the air handler components, including the blower and motor, to ensure they are free of dust and debris.

9. Train Staff on Basic Maintenance

While professional maintenance is essential, training building staff on basic HVAC maintenance can help in the early identification of issues.

• Filter Changes: Train staff to regularly check and change filters.
• Visual Inspections: Educate staff on how to perform basic visual inspections and identify signs of potential problems.

Commercial HVAC System Repair Tips

Commercial HVAC systems are complicated. Thus, it is recommended that you contact a professional for repairs. However, there are minor repairs that you can DIY to prevent major breakdowns. Here are some tips:

1. Repairing Leaky Air Ducts

Beginners can repair holes or tears in air duct seams with relative ease. First, you can feel drafts to find air escaping from the hole. Then, seal the hole using ductwork-approved metallic foil tape.

To keep the tape in place, reinforce it using duct mastic and sealant.

2. Changing the Air Filter

It’s one of the easiest tasks for keeping your HVAC system in good working order. You should only have to remove two screws from the AC unit at the bottom and there are typically four filters in it.
