Why Is My Furnace Loud?

Over time, one of the most common problems that can occur with any furnace in Southern California is when it starts running loudly.

Furnaces can start running loudly for a variety of reasons; the goal is to understand what’s causing the noise and start taking steps to resolve the problem either by yourself or hire a Rancho Santa Margarita HVAC company to help you with fixing the problems that your furnace may have.

In this article, we will provide you with some reasons for why your furnace is loud and what may need to be done to resolve this problem.

Understanding Loud Noises From Your Furnace

Loud noises can occur for a variety of reasons including the fan bearings wearing out or other issues like “delayed ignition”, a very dangerous problem which occurs because oil that’s been unburned has built up in your furnaces fire box chamber and it’s igniting when you start your heater up.

Since loud noises often indicate a major problem under the surface you should contact an HVAC specialist immediately to resolve this problem for you.

Is Your Heater Making Whistling Noises?

Another common problem with many heaters have is when they start to make “whistling” noises as they are running.

These noises often occur when there are gaps which have developed in the air ducts over time causing the “whistling” sound as the air is blowing through the ducts.

The solution to fixing this problem is to find out where exactly the whistling sound is coming from in your ductwork and to seal those gaps with duct tape until the sound stops.

If the whistling sound continues to persist after you’ve found holes or gaps in your ductwork and you’ve sealed them, another solution to the problem could be that you have a dirty air filter that needs to be cleaned or replaced.

What If the Noises Are Coming from The Motor?

Let’s say that you hear a “banging” sound when you turn your HVAC unit on, this sound is often caused by pressure changes when you turn your furnace on.

The banging sound can also be caused by ignition roll-out, a little “explosion” which occurs when the furnace is starting because the flame is bigger than it has to be.

What’s the solution to this problem? You should contact a Rancho Santa Margarita furnace repair specialist immediately to fix this problem for you because you never want to attempt to fix anything related to gas or oil in your furnace unless you are a trained HVAC repair specialist.

Are High Energy Bills a Sign That Your Air Conditioner Needs Servicing?

By Air Care Heating and Air Conditioning

Are you spending more money on energy bills for your home than you have in the past? If so, this is one sign that it may be time for you to have your air conditioner serviced.

Most air conditioners, like your furnace, need to be serviced at least once a year to keep them running smoothly and efficiently but unfortunately, many people neglect the proper care and maintenance of their A/C because they get busy, or forget about them, and the result is either poor performance or higher energy bills than normal.

Things That Can Go Wrong with An Air Conditioner

Like any machine, your air conditioner relies on a wide variety of parts and accessories to keep it running smoothly and when any of its internal systems begin to go out, the result is poor performance.

If your air conditioner is not currently running as it should, some of the problems that it’s experiencing could include the following:

  • Low refrigerant.
  • Refrigerant overcharge.
  • Holes in the A/C duct.
  • Dirty air conditioner coil.
  • Faulty installation.
  • Dirty air filter.

When Your Air Conditioner Is Acting “Weird”

Besides the things mentioned above that could be going wrong with your air conditioner, some of the other signs that your A/C is in serious need of repair include the following:

Weird Smells – If a burning smell is coming from you A/C unit this is a sign that it should be serviced immediately because your air conditioner is actually overheating, and there is something that’s actually burning inside of your A/C.

Don’t wait until you see smoke! Turn off your air conditioner and call a quailed air conditioner repair company today.

Strange Sounds – Like any appliance, your A/C will make some degree of noise that you’re most likely familiar with but, if your air conditioner starts sounding louder than normal this is a sign that you should have it checked out immediately before you’re A/C unit stops working.

Weak Air Flow – Last of all, but most important, if your air conditioner doesn’t have the same airflow as it once did, this is another sign that it’s in serious need of maintenance because an air conditioner with weak air flow means that it has to stay on longer resulting in higher energy bills for you.

Buying a New Furnace – How to Guide


Gas Furnace Buying Guide


The Heat is On

Are you considering replacing your furnace? There are several benefits to replacing your old furnace. New furnaces are more reliable, more efficient, and quieter. You will also experience a big boost in your homes comfort. But which furnace is right for you? Great question! Below we’ve listed a few items to consider before you decide on a furnace. 

Gas and propane are the most common heating fuel so this report focuses on gas and propane furnaces.


How do most homeowners go about buying a new furnace? Most will call contractors and ask for estimates. We did too, well sort of. We obtained over 500 estimates from local residential heating and air conditioning contractors and took into account experiences from over 100 clients, this is what we found.


Size Matters
The furnace should meet the needs of your home and existing air conditioning system. A furnace that’s too small won’t keep your home warm during coldest days of the year. To avoid that possibility, we found most contractors oversize most furnaces.

The initial installation cost is only one of the many drawbacks of that strategy. A furnace that’s too big will cycle on and off more frequently. That places greater wear on its components, wastes energy, and reduces the life expectancy of the furnace. 


Efficiency Also Matters
Gas and propane are currently the most common heating fuel sources. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the AFUE, the more efficient the furnace. One other thing to consider is the environmental impact of your furnace. Higher efficiency furnaces emit fewer emissions, therefore, higher efficiency furnaces are more environmentally friendly.

Like most products, furnaces have become more efficient over the years. A gas furnace manufactured in the 70’s typically has an AFUE of about 60%. The lowest efficiency allowed by the EPA for new gas furnaces today is 80% percent, and some models can achieve over 98% efficiency.


Most and Least Reliable Furnaces
If you have to replace your furnace, you’ll be glad to hear that a new gas or propane furnaces can save you up to 40% in heating costs. They are also much more reliable. 

Reliability is especially important because, according to consumer reports, when a furnace fails 77% of the time they need significant work. 

Most homeowners will be surprised to learn that there are about 150 brands of furnaces, but only 6 manufactures in the US. All that to say that nearly all furnaces are the same in terms of reliability. What we found to be the clear differentiating factor is who installs the furnace. Finding a trustworthy HVAC contractor is what matters most. 

It should come as no surprise then that in our survey of repair history, we found no statistically meaningful differences in percent of models ever repaired for the leading brands of furnaces.

Why is my Air Conditioner Blowing Hot Air?


You just noticed you’re A/C is blowing warm air, now that’s a reason to sweat.


No need to panic. There are several reason why your air conditioner could be blowing warm air, and most repairs are fairly simple.


Before you decide to call a professional, try these four common causes for A/C failure, all of which you can fix yourself.


Thermostat set to HEAT instead of COOL.


Yes, this happens a lot! Check your thermostat setting and make sure you didn’t accidentally set it to “HEAT” instead of “COOL”. It happens more often than you’d think, especially with digital thermostats.


Fan is set to ON instead of AUTO

If the fan setting at thermostat is set to “ON” the fan will circulate the air in your home constantly, even when the A/C isn’t on. This is a useful feature that can help improve the quality of the air in your home and can also help reduce hotspots.


DIY fix: Make sure your thermostat is set to “COOL” and use the “AUTO” fan setting.


Indoor or Outdoor Coil is Clogged

Your home’s AC system is made up of 2 main components a condenser, which sits outside, and an evaporative coil, which is inside. These components work together to remove heat from your home. To perform this task successfully, they require unrestricted airflow.

A condenser that is impacted with dirt, leaves or debris can keep your AC working properly. A dirty indoor filter can create the same issue.


DIY fix: You can prevent this problem by using a broom or hose to clean your condenser. Also make sure to trim bushes, weeds and tall grass that could restrict airflow. It’s a good idea to change your indoor filter ever 2-3 months.


Loss of Power to Condenser 

As we discussed earlier, your AC system is actually 2 parts that work together. If the outside unit loses power but the inside unit doesn’t, it is possible that you could experience warm air coming out of your air vents.


There are 2 places an outside AC unit can lose power:


At the circuit breaker. Check to see if the breaker for your outside unit got tripped.

An emergency shutoff switch. This is usually located on your home’s exterior wall, right by the outside AC unit. Check to see it’s in the “on” position.

DIY fix: Locate the breaker switch on your outside unit and flip the switch all the way OFF and then back ON.


Note: If your AC continues to trip your breaker, call a professional! This is a sign of a serious electrical problem in your air conditioner.



Why Is My Furnace Leaking Water?


As temperatures begin to rise, or drop, most homeowners don’t hesitate to start running their HVAC system. They may take a quick look at their furnace or condenser to make sure their running, if everything checks out then they continue with their daily chores, and that’s the way it should be.


A few days later they might be surprised to find a puddle of water collecting around their furnace or on the ceiling of their home. They are left asking themselves, “Why is my furnace leaking water?”


This is a common question we hear from our customers, and there’s a few reasons why your furnace could be leaking water. Below, we’ve outlined what might be causing your furnace to leak, but it’s best to let a professional HVAC contractor diagnose the issue as it could lead to serious damage to your home or air conditioning system.


Reasons Why Your Furnace Is Leaking Water


1.Condensation Leaks

Modern furnace models are more energy efficient than older units. As these newer heating systems pump cool exhaust away from your unit it may cause an increase in condensation collecting at the base of your furnace and is one reason why your furnace is “leaking” water. If you don’t have a high-efficiency furnace, you may have an incorrectly sized flue pipe, since standard efficiency furnaces do not produce condensatio


2. Clogged Condensation Drain

Your air conditioning system can condensate up to 3 gallons of water per hour as it runs. It is possible your condensation drain line is clogged, causing the condensation to back up and flood the furnace. Another possibility is that the condensation drain pan or drain line is cracked.
