During a service call, we determined that the home owner blower motor and capacitor needed changing. We ordered the parts and the home owner scheduled for a week out. We returned a week later and installed the necessary parts and now their unit is running to spec! Thank you for allowing us to service your HVAC, Mrs. J!

Long time customer called in during one of the coldest days of the year saying their system wasn't heating. Same day service, same day repair! They needed a new heat kit and system ran great!

May 20, 2026 | Mansfield, TX

Customer requested a routine maintenance service on their system. We inspected all wiring, safety switches, thermostat, and refrigerant levels, and everything checked out good. The indoor coil, blower wheel, and blower assembly were clean and operating properly. We washed the outdoor condenser coil and checked the compressor amp draw, which was within normal range. At this time, the system is operating properly and efficiently with no issues found.

Once we arrived at Mr. F's home and diagnosed their system, we determined that their dual capacitor had failed. We replaced and tested system, now the unit is running great!

Mrs. T. is a long time customer and has a maintenance agreement that she received with her new HVAC system she purchased from us last year. We inspected her heat pump system for the winter and everything looked great! See you next spring!

October 07, 2024 | Burleson, TX

Mrs. N. called us for an after hour service call because her AC stopped coming on. Once our tech diagnosed the system, he determined that the float switch is why the system wasn't coming on. It needed adjusting and we retested the system, now it's working to spec.

April 01, 2025 | Burleson, TX

We called Mrs. R. to perform her final complimentary maintenance that she received with the new system that she purchased in 2024. Everything was working to spec and the system looked good! Thank you for your business, Mrs. R!

October 19, 2023 | Mansfield, TX

Mr. B called in stating his tenant property wasn't cooling. Upon diagnostic we called the landlord to inform him of the necessary repairs and he accepted. Now the home is cooling and working great!

December 03, 2024 | Burleson, TX

Mr. B. called us when his heating system no longer worked. He had another quote from another company for repairs but wanted us to come out for a second opinion. Once arrived, we noticed that his older R22 system had a faulty board and needed replaced. We gave Mr. B. his options for both repair and replacement and they are discussing it as a family and will let us know when they make a decision.

May 21, 2026 | Burleson, TX

Customer called and reported that the air in the shop was not cooling properly. Upon inspection, we found significant air leakage at the supply plenum, which was causing loss of airflow and reduced cooling performance. We also found that the system only had one return, and the existing return air setup was inadequate for the size of the unit. We recommended increasing the return airflow and sealing the supply plenum to improve system efficiency and reduce air loss.

We scheduled a return visit to complete the recommended repairs and modifications. During the follow-up visit, we installed a new return grill, replaced sections of ductwork, and added an additional return duct to improve airflow throughout the system. After completing the work, the system was operating more efficiently with improved airflow and cooling performance.

Mr. H informed us of his rental property that needed it's coil cleaned. He inquired whether we would be able to do it in place, or pull the coil out and chemically clean it. His tenant has quite a few pets and this coil was in need of a chemical clean. The before and after speaks for itself!

What Bock Air Conditioning Customers are Saying

I had them come out and inspect my ductless mini split unit. They are knowledgeable when it comes to these types of units unlike many companies. If you have one in need of service or install give them a call. I will be using them from now on for regular service as well as installing my next unit.
