Regular Inspection and Cleaning

When looking into AC maintenance, it is important to understand what to expect when a professional comes to inspect your unit. An HVAC technician will begin with the air filter, as a clean air filter is essential for good air circulation and indoor air quality. They will check the air filter and replace it if it’s dirty. Additionally, they will inspect the condenser coil and evaporator coil for dirt and debris. Dirty coils can reduce the system’s efficiency and lead to higher energy bills. At Design Aire, we use specialized tools and coil cleaners to clean these components thoroughly as part of your routine AC maintenance.

Inspect Electrical Connections

Ensuring the electrical connections in your AC unit are secure is a crucial part of HVAC maintenance that should be handled by a professional. Loose or faulty electrical connections can lead to improper operation and pose a safety hazard. Technicians will inspect all electrical wiring and connections for signs of wear or damage, tighten any loose connections, and replace damaged wires immediately. This step helps maintain the proper operation of the entire air conditioning system and prevents the need for extensive air conditioning repair.

Check Coolant Levels and Drain Lines

Coolant levels are critical for the efficient operation of your air conditioning system. Low coolant levels can cause the evaporator coil to freeze and hinder the AC unit’s ability to cool your home effectively. Design Aire’s professionals regularly check the coolant levels and top them up if necessary. Additionally, they inspect the condensate drain line for clogs or blockages. A clogged drain line can cause water damage and reduce indoor air quality. Cleaning the drain line ensures proper drainage and prevents moisture-related issues in your AC system.

Ensure Outdoor Unit is Clear

The outdoor unit of your air conditioner needs to be free from obstructions to function efficiently. Professionals remove any yard debris, leaves, or plants around the outdoor unit to maintain good air circulation. This step is vital for the condenser coil to dissipate heat effectively. Technicians also check the unit’s foundation for stability and ensure it is level. Regular professional maintenance of the outdoor unit prevents overheating and ensures the system runs smoothly throughout the season.

Schedule Professional HVAC Service

While basic maintenance can be performed by homeowners, scheduling professional HVAC maintenance at least once a year is crucial. A Design Aire HVAC technician can conduct a thorough inspection, identify potential issues, and perform necessary AC repairs. This includes checking the heat pump, inspecting connections, and ensuring the system’s overall efficiency. Regular professional service can extend the lifespan of your air conditioning unit and save you money on costly repairs in the long run. Schedule your maintenance today!


By following this AC maintenance checklist with the help of professional service from Design Aire, you can ensure your air conditioning system operates efficiently and reliably. Regular maintenance not only improves air quality and comfort but also enhances the longevity and performance of your HVAC system.
