PHD HEATING AND COOLING INC. — No Surprise Invoices. Ever.
PHD HEATING AND COOLING INC. was founded in 2010 by veteran HVAC technician Marcus Delacroix, who specialized in precision system diagnostics and took pride in a meticulous installation ritual that most competitors skip: every ductwork joint is sealed with a custom-fitted gasket and inspected under magnification before final sealing. This attention to detail ensures long-term performance, reduces callbacks, and sets PHD apart as a premium service provider in the Chicago area.
Frequently asked
I specialize in servicing a range of data-center precision cooling systems, including in-row precision-cooling unit service carts, hot-aisle and cold-aisle containment panels, raised-floor airflow tile gauges, and humidity and dew-point sensor calibration kits. These are the core components that keep servers running efficiently and prevent overheating or condensation issues.
Yes, I provide a dedicated 24/7 emergency line specifically for urgent no-heat/no-cool calls related to data-center environments. This ensures that if there's a critical failure in your precision cooling system—such as a malfunctioning in-row unit or an airflow issue—you can get immediate assistance outside of normal business hours.
I recommend having humidity and dew-point sensors calibrated every 6 to 12 months depending on your environment’s stability. Regular calibration is essential for accurate readings that help prevent server damage from over-humidity or under-humidity conditions, which can affect system performance and longevity.
I’ve been working with raised-floor airflow tile gauges for over 16 years now. My experience includes diagnosing airflow imbalances, identifying blockages or damaged tiles, and ensuring optimal air distribution across server racks. Proper airflow management is crucial in preventing hot spots and maintaining consistent temperatures within data centers.
