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.

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.

Can a dirty air filter cause my AC to freeze up?

Yes, a dirty air filter is a common culprit behind a frozen AC unit. The restricted airflow caused by the dirty filter makes it difficult for the evaporator coil to absorb enough heat. This can cause the moisture in the air to freeze on the coil, forming a layer of ice that further restricts airflow and can eventually damage the compressor. Changing or cleaning your AC filter regularly (every 1-3 months) is a simple preventive measure to avoid this problem.

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.

How can I make my AC more energy-efficient?

Reduce energy consumption and save money with these tips:
  • Regular maintenance:
    • Schedule annual or biannual professional tune-ups to keep your system in peak condition.
  • Programmable thermostat:
    • Optimize temperature settings based on your schedule and occupancy.
  • Seal air leaks:
    • Prevent air leakage by sealing gaps around windows and doors.
  • Adequate insulation:
    • Ensure proper insulation to minimize heat gain and loss.
  • Strategic landscaping:
    • Plant trees or shrubs to shade your home from direct sunlight.
  • Ventilation:
    • Improve ventilation to remove excess heat and humidity, reducing reliance on AC.
  • Energy-efficient windows:
    • Upgrade to double-paned or energy-efficient windows to keep heat out during hot spells.
  • Regularly clean/replace air filters:
    • A clean filter optimizes airflow and efficiency.
  • Consider upgrading your unit:
    • Older models are usually far less efficient. . If your unit is over 10 years old, consider replacing it with a high-efficiency model.
Small changes make a big difference!
