Homeowners can perform some routine maintenance tasks to keep their AC unit in good condition, while the experts at Qual-Tech have the training and tools to perform more comprehensive inspections and repairs. Here’s a breakdown of what homeowners can do to extend the life of their AC unit and what you should leave to the experts:

Homeowner Maintenance

Cleaning or Replacing Filters

Homeowners can clean or replace air filters regularly, typically every one to three months, to ensure proper airflow. Dirty filters can reduce efficiency and indoor air quality.

Clearing Debris

Keep the area around the outdoor condenser unit clear of debris, leaves, and dirt. Trim vegetation to ensure adequate airflow.

Thermostat Settings

Set the thermostat to an efficient temperature and adjust it as needed for comfort. A programmable thermostat can help homeowners optimize cooling when they're away.

Sealing and Insulation

Homeowners can seal gaps and cracks around doors and windows to prevent cool air from escaping and warm air from entering. Proper insulation is also essential.

Shade and Ventilation

Using blinds, curtains, or shades to block direct sunlight and using ceiling fans to circulate air can help reduce the load on the AC system.

Regular Cleaning

Homeowners can visually inspect and clean the condenser coil with a hose to remove dust and debris.

Interior Vents

Ensure that interior vents and registers are not blocked to maintain proper airflow.

Qual-Tech was recommended and we are very pleased with their service. John was very professional and friendly over the phone. Christian was attentive and very informative with servicing our unit. We will definitely be using Qual-Tech again for our a/c needs. Thank you!

Qual-tech saved the day! 112 degrees today. John was able to get his technician, Christian, out the same day that they received the request. Christian arrived on time and took about 10 minutes to diagnose and to make the fix (he says it was the dual capacitor). Now, we just have to wait for the house to cool from 91 degrees. 😬 Thank you, gentlemen!

We recently had our 17-year-old HVAC replaced by Qual-Tech. From the first technician we met, George, to their install manager, Christian, and the entire install team, we were very impressed by their professionalism, honesty, timeliness, and courtesy. The owner, John, was always available to answer questions and did a great job communicating throughout the process. I highly recommend Qual-Tech for anyone looking for knowledgeable and quality HVAC service!

The Qual-Tech team were amazing to work with. Their followup was excellent. The gentleman that came out, George, was very knowledgeable and took the time to explain what the issue was. He was very careful entering the attic access inside the house and cleaned up once he finished. Everything is working fine, thank goodness with the cold weather that has entered the Surprise area. I would highly recommend Qual-Tech air conditioning / heating to anyone.
