🏊‍♀️ A Pool Heat Pump Installation in South Pasadena, FL! ☀️

Our team recently replaced an existing pool heat pump for a customer in South Pasadena with a brand-new 4-ton AquaCal HeatWave SuperQuiet pool heat pump!

This new system can heat and cool the pool, helping keep the water comfortable and extending the swimming season—even when temperatures start to drop. 🌴

Our team handled the entire installation, including the necessary plumbing and electrical connections, removal of the old equipment, and cleanup. We were also able to reuse the existing concrete pad!

🔧 Commercial HVAC Repair in Chantilly, VA 🔧
Keeping our customers comfortable is what we do best!

One of our technicians, Kevin, was recently on-site in Chantilly replacing a failed fan motor on a commercial HVAC unit. A faulty fan motor can reduce system performance, increase energy costs, and even lead to a complete system shutdown if not addressed promptly.

Our team quickly diagnosed the issue, replaced the motor, and got the system back up and running to help keep the building comfortable for employees and customers alike.

If your commercial HVAC system isn't performing as it should, give Mannix Heating & Cooling a call. We're here to help with repairs, maintenance, and system replacements throughout Northern Virginia.

Peak Performance Tip - Give your system space.
Your outdoor unit needs breathing room. Clear grass clippings, leaves, and patio items away from it so air can flow freely. Better airflow helps performance and can reduce strain on hot days.
