Signs You Need Emergency HVAC Service

Heating and cooling issues need to be addressed quickly to prevent uninhabitable indoor temperatures and damage to your home.

If you notice any of the signs below, don’t hesitate to contact Len The Plumber Heating & Air for air conditioning or heating repair:

  • No heating or cooling
  • Strange noises from the unit
  • Strange odors from the unit
  • Ice on the AC unit
  • System short-cycling
  • Inconsistent temperatures

Regular heating and AC maintenance can often prevent these issues, ensuring your system runs when you need it most. We recommend scheduling annual tune-ups for each system.

Common Causes of AC Breakdowns

We can provide emergency service whether you have a central air conditioner or ductless mini-splits.

The issues we most often see causing AC breakdowns include:

  • Dirty filters: Clogged air filters restrict airflow, making your AC work harder, causing the system to overheat and driving up your utility bills.
  • Electrical issues: Faulty wiring or worn-out components can cause your AC to malfunction or not turn on at all.
  • Frozen evaporator coils: Restricted airflow or low refrigerant levels can cause the coils to freeze.

Common Causes of Heating Breakdowns

We service furnaces, boilers, and heat pumps to help Northern Virginia homeowners stay warm during our freezing winters.

Common problems that cause these heating systems to malfunction and break down include:

  • Ignition or pilot light issues: For furnaces and boilers, problems with the ignition system or pilot light can prevent the system from producing heat.
  • Water or fuel leaks: In boilers, leaks can cause low pressure and prevent your boiler from heating at all. If you have a gas furnace, a fuel leak is extremely hazardous and should be addressed immediately.
  • Faulty reversing valve: If your heat pump can’t switch to heating mode, you need fast help to restore warmth to your home.

Frequently Asked Questions

What should I do if my HVAC system breaks down?

Call an emergency HVAC company as soon as possible. While you wait for the technician to arrive, you can take steps to stay comfortable.

In summer, avoid using heat-generating appliances or opening windows, as these can contribute to heat gain. Instead, turn on ceiling fans and stay hydrated.

In winter, turn on space heaters in occupied rooms and bundle up with clothes and blankets.

How do I troubleshoot my HVAC unit?

Start by checking and replacing air filters, ensuring the thermostat is set correctly, and ensuring all vents are open and unobstructed. You should also check the circuit breaker to make sure it hasn’t tripped.

Call our team for repair if these steps don’t resolve the issue.

How do I know if I should repair or replace my HVAC system?

A newer system is usually repairable. However, if your system is over 10 years old and requires frequent repairs, it may be more cost-effective to replace it. Len The Plumber Heating & Air provides expert air conditioning and heating installations if needed.
