Filed claim with insurance and was called by Qual-Tech the next morning and they scheduled me for that afternoon. Richie was here last week and diagnosed my AC unit with a bad board. This week he returned with a new board and installed it and after running some tests he diagnosed the system low on coolant. Its an old system, so its definitely time for an upgrade.They took care of the issues, and within a few minutes after install and diagnosis I was contacted by another company to schedule to top off my system. Service and workmanship was great and very prompt about timing and completing the job. Highly recommend Qual-Tech.Posted on Google![]()

Richie was a nice young man who worked hard to find the problem with A/C. He answered my questions and was very helpful. Unfortunately, the leak couldn’t be located, but he explained what steps we would need to take.Posted on Google![]()

I can’t say enough good things about Qual-Tech Air Conditioning & Heating. From the very beginning, they were honest, professional, knowledgeable, and genuinely cared about solving the problem rather than just trying to sell me something. It’s refreshing to deal with a great family-owned business that takes pride in their work and treats their customers like people, not dollar signs. We were having issues with the airflow and temperature balance throughout the house. Qual-Tech came in, evaluated everything, added the necessary dampers, and reworked the airflow to get everything balanced properly. The difference has been incredible. While they were working, they also discovered an old duct run from a previous swamp cooler that had simply been taped off and shoved into the insulation instead of being properly removed. They took the time to identify it and address the issue rather than overlooking it. What really stood out to me was their honesty and attention to detail. They could have easily done the minimum and moved on, but instead they took the time to find the underlying issues and make sure the system was operating the way it should. If you’re looking for an HVAC company that is honest, knowledgeable, thorough, and actually cares about doing the job right, I highly recommend Qual-Tech Air Conditioning & Heating. Supporting a family-owned business like this is easy when they provide this level of service. I’ll absolutely be calling them for any future HVAC needs.Posted on Google![]()

I had a great experience with Qual-Tech getting my ac fixed. They did a great job dealing with my home warranty company, who has been less than easy to deal with. I appreciate the help from Qual-Tech and would recommend them to family and friends.

Semiannual AC maintenance in Glendale keeps your system efficient and dependable before the busiest cooling and heating seasons. A spring tune-up prepares your AC for summer, while fall service inspects heating or combined HVAC components to ensure stable performance year-round.
Skipping maintenance can lead to higher repair costs or early system failure.
Without regular AC maintenance in Glendale, dust and debris accumulate, efficiency drops, and small issues may go unnoticed until they become expensive repairs. Over time, this reduces the lifespan of your AC, increases energy usage, and raises the risk of a breakdown when you need cooling the most.
Most visits take between 1 and 2 hours.
The exact timing depends on your system’s size, age, and condition. During a typical AC maintenance in Glendale appointment, a technician will check refrigerant levels, clean critical components, test system controls, and verify safe operation. Identifying issues early helps prevent longer, more costly repairs later.
Weak airflow, unusual noises, or rising energy bills are common warning signs.
Other signs include musty odors, uneven cooling, or frequent cycling. Routine AC maintenance in Glendale can catch these issues early, restore performance, and prevent further damage.
You can handle basic upkeep, but professional service is essential.
Replacing air filters and clearing debris around outdoor units are helpful DIY steps. However, internal cleaning, electrical checks, and refrigerant inspections require tools and expertise.
