Is Your Heater Suffering from Reduced Air Flow?

Tuesday, November 22nd, 2016

Most homes in the greater Los Angeles, CA area rely on forced-air furnaces to generate heat in the winter. These systems use gas burners or electric coils to heat the air in their chamber, then blow the air through the ducts into your home. It’s a safe and reliable system, but it can encounter trouble from time to time, like any system. And that can include a reduced air flow from the vents.

The furnace could be functioning exactly as needed, but if the air doesn’t get where it needs to go, it’s going to cause some serious problems. The causes are usually fairly simple — a problem with the fan motor, bent fan blades or some manner of blockage in the vents themselves — but unless those problems are identified by a trained technician and corrected, it could add up to a very expensive repair.

What Are My Options for Heating Installation?

Tuesday, March 17th, 2015

Spring can be a great time to install a new heating system, but the amount of options homeowners have for new heating systems can be overwhelming.

The experts at AZ Air Conditioning and Heating can help you with your new heating installation from beginning to end, including reviewing your heating options with you. Your heating system is going to be with you for a long time, so it’s important to choose wisely. Understanding how certain systems work and what they can offer you are important to your heating installation in Santa Monica, so here are some of the options available to you from AZ Air Conditioning and Heating:


Furnaces are very common heating systems in homes; it’s estimated that 60% of homes across the nation use a furnace for heating. There are two types of furnaces available to homeowners: gas or electric. Both types need ductwork to operate. There are a number of similar parts between the two types, but they generate heat differently.

Heat Pumps

Heat pumps are 2-in-1 devices because they offer your home both heating and cooling. They work by transferring heat from one location to another; this means they do not generate heating or cooling, and therefore do not use any fossil fuels nor do they require a great amount of electricity. Heat pumps can work with ductless or ducted systems.

Which System Is Best for Me?

Deciding which heating system is best for your home is going to depend on your needs, whether or not you have ductwork and lastly, what your preferences are. For instance, a gas furnace won’t be an option for you if you don’t have access to a natural gas line. As another example, a heat pump may not be for you as you may just have installed a new air conditioning system and don’t require a 2-in-1 type of device.

Working with a trained heating expert, like the ones at AZ Air Conditioning and Heating, can help you determine which heating system will be best for heating installation in your Santa Monica home. Call us today and schedule an appointment with one of our professionals.

Common Furnace Blower Problems

Friday, January 16th, 2015

There are multiple components in your furnace, but there are three that have the majority of the work when it comes to heating your home: the burner, the heat exchanger and the blower. Today we’re going to talk about common blower problems as any issue with your blower can affect the quantity and quality of the warm air that gets blown into your home.

What Is a Blower?

The job of the blower is to push the warm air generated by the burner and heat exchanger (or heating element, in the case of an electric furnace) into your home. A special device called a limit switch keeps track of the temperature of the air around the heat exchanger so that the blower only turns on when the air is warm enough; otherwise, you would have cool air blowing through your vents. The blower has several components itself: a motor, a belt and fan blades. Each has its own job and when something is wrong with any of these components, it can affect the operation of the blower.

Common Problems

Here are some of the more common problems our technicians see with furnace blowers:

  • Bent/loose fan blades – the fan blades of the blower can become loose, and sometimes if they become loose enough, they can hit other parts surrounding them, and become damaged. While a loose or bent fan blade doesn’t necessarily affect the operation of your fan, a single loose blade can cause damage to items around it.
  • Worn belts – the fan belt in your blower can become cracked, stretched and worn out over time, which will affect the rotation of the fan.
  • Dry ball bearings – there are a number of ball bearings on the blower that help it turn, and they need to stay lubricated; if they don’t, they can grind and cause problems with friction.
  • Motor issues – the motor of the blower is responsible for powering the rotation of the fan, so any problems with the blower will directly affect the operation of the fan.

It may be tempting to repair your blower, but this is never a good idea. Your furnace repairs in Glendale should always be handled by trained and certified experts, so call the ones you can trust: AZ Air Conditioning and Heating.

3 Common Gas Furnace Repairs

Friday, December 5th, 2014

Gas furnaces are among the most common home heating systems in the United States. They’re relatively cheap, easy to install, and fairly easy to repair. Just like any home heating system, however, they have the occasional breakdown. Here are the three most common gas furnace repairs that you’re likely to encounter.

Pilot Light Won’t Stay Lit

The pilot light is a continuously burning flame located underneath your furnace. It is there to ignite the burners, which serve as the furnace’s heat source while it is running. As the pilot light is often unprotected, it can occasionally blow out if exposed to a draft or other strong air current. Relighting the pilot light is a fairly simple affair. The real problem occurs when your pilot light refuses to stay lit. This is usually the sign of a bad thermocouple.

The thermocouple is a sensor that is responsible for making sure that the pilot light keeps receiving gas to burn. A bad thermocouple has lost the ability to sense the heat from the pilot light, causing it to cut off the supply of gas and smother the flame.

Dirty Air Filter

Every furnace contains an air filter, designed to protect it against the dust and debris that is common in ductwork. As an air filter gets older, however, it becomes clogged with the same dust and debris that it was protecting the furnace from. A clogged air filter can restrict the flow of air to the furnace, causing heat to become trapped in the unit. This can lead to the furnace overheating, which will cause it to shut itself down rather than risk a fire.

Cracked Heat Exchanger

The heat exchanger serves two roles in the furnace. First, it is responsible for heating the air as it flows through the furnace. Second, it serves as a channel through which toxic combustion gases travel to get to the exhaust flue and out of the house. Years of wear and tear can cause the heat exchanger to develop small cracks, allowing the combustion gases and air from the house to mix. This is a major threat to health and safety, which is why a cracked heat exchanger needs to be repaired or replaced as soon as possible.
