Frequently Asked Questions About AC Repair

Is your AC unit not cooling properly? Are you hearing strange noises or noticing unusual smells? Find answers to common questions about AC repair and connect with qualified HVAC technicians in UK.

Why is my AC fan not spinning?

Several issues can cause your AC fan to stop working. . Here are some possibilities:
  • Faulty capacitor:
    • The capacitor gives the motor a boost to start. A faulty capacitor can prevent the fan from starting.
  • Malfunctioning motor:
    • The fan motor itself might have failed.
  • Worn-out belt:
    • If your AC has a belt-driven fan, a worn or broken belt can prevent it from spinning.
  • Electrical issues:
    • Wiring problems or a tripped circuit breaker can cut off power to the fan.
  • Frozen unit:
    • Ice buildup can block the fan blades..
It's essential to contact a qualified HVAC technician to diagnose the issue and ensure safe and proper repair. .

What is the difference between a central AC and a heat pump?

The key difference between a central AC and a heat pump lies in their functionality. A central AC system only cools, relying on a separate furnace for heating during colder months. A heat pump, on the other hand, provides both heating and cooling. It can extract heat from the outdoor air even in relatively cold temperatures (down to a certain point), providing efficient heating. In summer, it reverses the process to cool your home. Heat pumps are often a more energy-efficient choice than a separate AC and furnace, especially in mild to moderate climates.

How do I know if my AC needs repair?

Several indicators can signal that your AC unit needs repair:
  • Warm Air from Vents: Instead of cool air, your vents are blowing warm or room-temperature air.
  • Insufficient Cooling: The AC is running, but your space isn't cooling down sufficiently.
  • Unusual Noises: Squealing, grinding, banging, or other odd sounds are often signs of mechanical issues.
  • Strange Smells: Burning odors, musty smells, or other unusual odors indicate potential problems like electrical issues or mold growth.
  • Leaking Water: Water leaks around the indoor unit can indicate a clogged drain line or other drainage problems.
  • High Energy Bills: A sudden increase in your energy bills might be due to a struggling or inefficient AC unit.
  • Short Cycling: The AC unit turns on and off frequently, without completing a full cooling cycle.
If you experience any of these, contact an HVAC repair professional promptly. Early intervention can prevent minor problems from becoming major expenses.

What does SEER mean in AC units?

SEER stands for Seasonal Energy Efficiency Ratio. It's a measure of how efficiently an air conditioner cools your home over an entire cooling season. It is calculated by dividing the total cooling output (measured in BTUs) by the total electrical energy input (measured in watt-hours). A higher SEER rating indicates greater energy efficiency. For example, an AC unit with a SEER rating of 16 is more efficient than one with a SEER of 14. Modern, energy-efficient AC units have SEER ratings ranging from 14 to 26. The higher the rating, the less energy the AC unit consumes, resulting in lower energy bills.
