Why Is My AC Running But Not Cooling The House?
An AC often runs but doesn’t cool when airflow is restricted, refrigerant is low, controls are mis-set, or the compressor can’t move heat outside. The most common cause is a clogged air filter that chokes airflow and lets the coil freeze, so the system blows warm. Other times the outdoor coil is packed with yard debris, the thermostat is on “fan” instead of “cool,” or a failing capacitor keeps the compressor from…
What is the average cost to fix a furnace?
The average cost to fix a furnace isn’t one set number; Diamond Heating and Cooling confirms pricing after an on‑site diagnostic because the fault, parts, and labor drive the total. The most common driver of cost is the specific failed component, while age and maintenance history influence whether a repair or replacement makes more sense. We provide clear, written estimates before any work. Non‑members can use our…
What Does HVAC Repair Usually Include For Homeowners?

Why Is My Air Conditioner Not Turning On Despite Thermostat Set to Cool?
An air conditioner not turning on with the thermostat set to Cool usually means the system isn’t receiving the start signal or a safety device is holding it off. Most problems come from lost power, control setting errors, or a condensate overflow switch that stops cooling to prevent leaks. If the indoor blower runs but the outdoor unit is silent, a failed capacitor or contactor is a top suspect. In our Treasure…
