A customer reached out to us after another company installed a motor that started making unusual noise. Suspecting an issue, they called us for a thorough inspection. Upon examination, we discovered that the previous company had wired the wrong size capacitor to the motor, resulting in excessive voltage. This caused the motor to overheat significantly, reaching 186° despite the ambient temperature being 78°. The overheating damaged the bearings, leading to the noise. Our commitment to quality and fair pricing reassured the customer of our reliability.

I visited the site to assess an outdated, non-functional heat pump. Upon inspection, I identified several issues, including a faulty compressor, damaged wiring, and a clogged air filter. I provided a comprehensive evaluation and a detailed quote for the replacement of the heat pump system. This included the removal of the old unit, installation of a new, energy-efficient model, and a thorough system check to ensure optimal performance. The new unit was chosen based on its energy efficiency and compatibility with the existing infrastructure. I ensured all components were securely installed and tested the system to confirm it was working correctly. The customer was provided with a clear, itemized quote and guidance on maintenance to prolong the new system's lifespan.

During the installation of air filters on commercial equipment, attention to detail is crucial. Typically, gaps between filters can allow debris to pass through, but this was avoided by meticulously cleaning and protecting the coils. Each filter was carefully inspected, ensuring no debris could enter. The coils were cleaned thoroughly, removing any accumulated dust or dirt. A protective barrier was added to seal the gaps, preventing any potential leaks. This process took an extra minute and required an additional $0.30 in materials, but it guaranteed the equipment would function optimally. The result was a system that operated efficiently, with no risk of debris infiltration. This commitment to quality ensures the longevity and performance of the equipment.

Dominic has completed two repairs for me in the last 6 months. First my blower motor went out, which he repaired, then a few months later my fan stopped working and he came to fix that. Scheduling was easy, Dominic was honest and didnt try to upsell me into something I didnt need, and his pricing was very reasonable. It's comforting to know I have an honest HVAC company to reach out to when I need them!

A customer's aging HVAC system was experiencing issues with airflow. Upon inspection, it was determined that the root cause was a faulty fan motor. The old unit was carefully disassembled to access the motor. After confirming the motor's failure, it was replaced with a new, high-efficiency model. The system was then reassembled, and a thorough test run ensured the new motor was functioning correctly. The customer was pleased to see the unit operating smoothly once again, with improved airflow and energy efficiency.

One of our A/C units was not blowing cold air and Dominic came out on short notice. He immediately introduced himself and was very respectful...even asked if he should take off his shoes in the house. My wife would very much appreciate this! He was very thorough in explaining the issue and what repair options there were and the associated pricing. He even discounted a few things. Very transparent and I never felt pressured!! He was able to make the repairs same day and get our unit back to functioning correctly. Would highly recommend you consider Dominic for your HVAC needs.

Successfully completed the task, ensuring the customer is well-prepared for the upcoming season. I meticulously repaired the unit on the right, addressing any issues to restore its optimal functionality. Both condensers were thoroughly cleaned, removing any accumulated dirt and debris to enhance efficiency and performance. The system was tested to confirm that it operates smoothly and effectively. This comprehensive service ensures the unit will perform reliably throughout the warmer months, providing consistent comfort and efficiency.

Upon inspection, the newer unit had developed a refrigerant leak, rendering it incapable of cooling or heating. I began by identifying the leak's source and made the necessary repairs. Following industry standards, I pulled a vacuum on the system to remove any moisture and non-condensables. The system was then charged with the correct refrigerant by weight, according to the manufacturer's specifications. To ensure the system's integrity, I conducted a thorough pressure test. The entire unit and roof were cleaned to remove any debris or contaminants. After confirming the system's functionality, I tested it to ensure optimal performance. The unit is now fully operational, providing reliable cooling for the upcoming hot months.

Repaired this heat pump by replacing the screeching, overheating, over amping fan motor, giving it a good cleaning, clearing out condensate drain and checking the overall operation. Even though it’s been operating for 7 years, it’s a little out of the refrigerant charge range and the airflow is too low. This is why it’s important to have maintenance, it may be working, but it might not be optimal.

Doing some light commercial winter maintenance. The customer did not even know that the compressor has failed and needs replaced or replace the equipment to get heating and cooling again. This is why maintenance is so important, to catch issues before they’re big issues when you need hvac the most.

Even though it’s a furnace checkup, I found this drain pan completely rusted out. The amount of work needed on these 23 year old furnaces makes it make sense to really think about replacing the systems. #hvacreplacement, #acreplacement,

Removed 2 smaller units and installed 1 large high efficiency system. Had to do duct work in the attic to connect both systems air flow. This actually ended up costing about the same as 2 smaller entry level systems. #Americanstandard #480Mechanical #heatpumpinstall #4805256900

AC compressor stopped last night. Reached out to 480 Mechanical as my neighbors gave them good reviews. They were able to squeeze me into the schedule the next day. Bad capacitor. He replaced and the unit was back up and running. Dominic was prompt, courteous and efficient. Very enjoyable experience.
