Types of Heater Issues We Repair

At AES Heating and Air Conditioning, we service all types of residential heating systems, even if we didn’t install them. We repair:

  • Gas and electric furnaces
    We handle all main furnace difficulties, from ignition failures to insufficient heat or airflow problems.
  • Wall and floor heaters
    Older or space-saving wall and floor units often malfunction over time, and we repair and diagnose them.
  • Central heating systems
    If your central heating struggles to maintain comfort, we’ll uncover the fundamental cause.
  • Rooftop package units
    These tiny, all-in-one systems are ubiquitous in LA homes and need adequate upkeep to work successfully.
  • Heat pumps and hybrid systems
    We fix both basic heat pumps and dual-fuel hybrid systems that combine gas and electric heating.
  • Mini-split systems with heating
    Ductless units often include heating. We also take care of this.
  • Models that are no longer made or are older
    We have parts for many brands of heaters, so even if yours is old, we can usually get it working again.

When to Call for Heater Repair

Problems with the heater aren't always clear. Keep an eye out for these symptoms that your system requires professional help:

  • No heat or air that never becomes warm
  • Heating or cooling that isn't even between rooms
  • Strange scents, like burnt, musty, or gas-like smells
  • The heater makes banging, buzzing, or other strange sounds
  • The heater won't switch on or runs all the time
  • When the heat comes on, the breaker trips
  • Winter energy expenses that are higher than normal

Don't wait to take action if your house feels cold or if your heater appears to be malfunctioning. We'll look at your system and fix the problem right away.

Why Quick Fixes Are Important

If you don't fix small heater problems, they can turn into big ones. Quick fixes can:

  • Get heat and comfort back quickly
    We'll make your home warm again, usually the same day.
  • Avoid dangers from fire or gas
    We look for leaks and other hidden dangers in heaters that don't work right.
  • Make the system last longer
    Finding problems early on keeps your heater running longer and avoids wear and tear.
  • Cut down on your energy costs
    A heater that works well uses less energy and spreads heat evenly.
  • Don't let things break down without warning
    Fixing things early will help you avoid expensive emergency calls or assistance after hours.

Our staff finds the real problem and fixes it in the best manner.

Frequently Asked Questions About Heater Repair Services

What’s the difference between a furnace and a heater?

A furnace is one type of heater. “Heater” is a general term and can refer to furnaces, wall units, mini-splits, or other devices that generate heat.

Do you repair both electric and gas heaters?

Yes — we’re licensed to handle both, including pilot systems, igniters, thermostats, and circuit issues.

How much does it cost to repair a heater?

We offer free diagnostics and provide a clear, flat-rate quote before any repair. Pricing depends on the issue and system type.

Is it safe to use my heater if it smells like burning?

A slight dusty smell is normal when first turning on heat. If it continues or smells sharp, like plastic or gas, turn it off and call us immediately.

Can you repair older wall or floor heaters?

Yes. We service a wide range of heating systems, including many older models that others don’t touch.

How long do heater repairs take?

Most repairs are completed on the same day — especially if we’ve diagnosed the issue early.
