HVAC load, airflow, and efficiency decisions in minutes, not callbacks.

Do a homeowner AC tune-up: clean the outdoor condenser coil, change the filter, clear the condensate drain, and check the supply-to-return temperature drop.

Do a homeowner furnace tune-up: change the filter, clean the blower area, clear the condensate drain, and test ignition and the thermostat each fall.

Decide whether a system is correctly charged, undercharged, or overcharged using the superheat method (fixed orifice) or subcooling method (TXV), and correct it safely.

Clean an oxidized furnace flame sensor to fix short cycling and ignition lockout, restoring a steady flame and reliable heat in about thirty minutes.

Clean the outdoor AC or heat pump condenser coil with a garden hose and coil cleaner to restore airflow and cooling, without bending the delicate fins.

Estimate the refrigeration capacity for a walk-in cooler or freezer by summing transmission, infiltration, product, and internal loads, then scaling for run time and a safety factor.

Clear biofilm and debris from the PVC condensate drain line on a central AC or high-efficiency furnace to prevent overflow shut-offs and water damage.

Safely replace a failed furnace blower or condenser fan run capacitor, including the required discharge step, to fix a motor that hums but will not start.

Replace a 24-volt low-voltage thermostat with a new one: map and label the wires, mount the new unit, then verify both heating and cooling switch on.

Install a Wi-Fi smart thermostat such as Nest or Ecobee, including the C-wire decision, wiring, and setup, so your heating and cooling run reliably.

Take accurate superheat and subcooling readings on a refrigeration or A/C system using a manifold/probe set and a PT chart, so you can judge charge and metering performance.

Replace your central HVAC air filter and pick the right MERV rating for residential blowers to improve air quality without choking off system airflow.

Seal accessible supply and return duct joints with water-based mastic and mesh tape to cut duct leakage, recover lost airflow, and lower energy bills.

Select first-pass suction and liquid line sizes for an A/C or refrigeration system from capacity, application, and equivalent line length, then verify against the equipment line-size chart.
