What Clicking Noises From Your AC May Mean

Friday, May 22nd, 2020

What-clicking-noises-from-your-ac-may-mean

Is your AC making noise? Generally speaking, any unusual sound coming from your air conditioning system is cause for concern.

Common Air Conditioner Noises

Here in Fairfax, VA, our air conditioning repair techs can handle your air conditioning problem. However, it does help if you, as the homeowner, have some idea of what specific sounds could indicate. When you can guess where the noises are coming from, you can point the repair professional in the right direction. Here are some of the most common air conditioning noises and what they may mean:

1. AC Clicking Noise

You may hear a clicking noise when you start your system up or even after it turns off. Sometimes, an AC clicking noise can stem from fan blades that have been bent or are misaligned which causes AC clicking on and off sounds. Alternately, a stick or piece of detritus could have gotten caught in the vent, causing the fan to click against it. In these cases, the cause is apparent, and the repair technician can either properly align the fan or replace it with a new model.

More subtle clicking noises can be a part of the air conditioner’s normal operation. For example, these sounds could come from a relay or a contact performing as expected. In those cases, the clicking should stop shortly. If they repeat, however, it could mean a problem with your thermostat or compressor turning the relays on and off repeatedly and increasing wear and tear in the bargain. If you hear repeated clicking from your AC, you should call for a repair. Possible electric problems should never be ignored when an AC clicks on and off.

2. Buzzing

If your air conditioner is making a buzzing sound, it is likely an electrical malfunction caused by loose or broken parts, leaks or compressor issues. If you suspect an electrical problem, turn off your system and contact a professional.

Buzzing could also be an indicator that your air conditioner’s “isolation feet” — the rubber legs at the base of your machine that support it — are wearing out. Buzzing might also mean a condenser coil, air filter or blower inside your system needs to be changed or replaced.

3. Clanking or Rattling

If your air conditioner is making a lot of loud clanking or rattling noises, it could mean a part has come loose and fallen into a different component of the machine. Before you call a maintenance specialist, make sure you check that all visible screws and bolts are tightly secured, so you can eliminate that as a possibility.

If your air conditioner gets too cold, ice and excess moisture can also build up inside and cause a loud grinding noise, accompanied by rattling movements. If you think your air conditioner has frozen, turn it off and allow it time to thaw.

Why Your Gas Furnace Won’t Work When the Power Goes Out

Friday, November 16th, 2018

Gas Furnace Power OutWhen the weather outside is cold and windy, there’s nothing as enjoyable as a nice warm furnace inside your home. After all, it’s much more reliable than a baseboard heater or other form of electric heat, right? If you lose power in a storm, those electric types of heat will falter and leave you with a cold house. Your natural gas furnace would never do that, right?

Unfortunately, that’s not entirely true. If you’ve ever asked yourself if a gas furnace works during a power outage, the answer is that it is just as susceptible to power outages as electric heaters. While it might seem counterintuitive and confusing, your gas furnace still depends on electricity to power itself and heat your home. If the power is out, the odds are good your furnace will be out as well.

There are plenty of reasons why your furnace works the way it does and how you can interpret what’s going on in your current situation. There are also many options you can try if it seems like the power has returned, but your furnace hasn’t. If you’re experiencing a gas furnace with no power and wondering what to do when the power’s out, we’ve compiled this quick and easy guide just for you.

There’s Ice on My Heat Pump—Is This a Bad Sign?

Thursday, December 28th, 2017

If you know even a little bit about the operation of the heat pump that keeps your household cool in summer and warm in winter, you’ll understand that the outside unit needs to absorb heat from the ambient air and carry it indoors in order for it to work in heating mode.

Should you notice that there is ice developing along the outdoor cabinet of the heat pump, it may worry you. Is this normal during the winter?

The answer is, confusingly, both yes and no. But we will quickly unconfuse you below:

What Kind of Issues Lead to Subpar Furnace Performance?

Sunday, December 10th, 2017

Furnace problems always arise at the least convenient times. We need reliable heating to keep our Fairfax, VA homes toasty and comfortable when the snows start to fall. And they don’t always need to involve a full breakdown either. In some cases, problems can lead to subpar performance, where the furnace continues to function but requires a lot more time and energy to do its job. What kind of issues lead to subpar furnace performance?

Some of it comes down to plain old-fashioned dust and build up. If you don’t have your furnace routinely maintained, then dust and dirt will accumulate on it. That increases friction on moving parts, as well as coating the pilot light and other key components with grime that might affect the furnaces performance. It will thus work harder in order to do the same basic job, and your monthly costs will go up as a result.

Similarly, a leak in the ducts, or a problem with one of the burners or another component will slowly leech your furnace’s productivity. Say, for example, that your furnace uses six burners. If one of those burners is faulty, the remaining five should still be able to generate enough heat to cover your home. Only they will have to use more fuel to do so and will take longer to heat your home. Again, this will end up costing you more in terms of your monthly heating bills, and the issue will likely get worse the longer the faulty component is left unrepaired.

Finally, sometimes simple age is enough to create a subpar performance. An older furnace not only has years of wear and tear to deal with, but may not be able to take advantage of new advances in technology, leaving it less efficient than more contemporary models.

If you think you are getting sub-par performance from your furnace, the next step is to contact a qualified professional to address it.  Give OASIS Heating, Air Conditioning & Refrigeration Inc. a call to set up a Fairfax, VA  furnace service today!

Problems with Your Electric Furnace? Let’s Look into It

Tuesday, December 5th, 2017

Not every house has a connection to a natural gas line, and some homeowners prefer the safety of only relying on electricity to power appliances. For these homes, an electric furnace is always a good alternative source for warmth. Along with their flexibility, electric furnaces tend to have longer service lives than gas furnaces and they cost less upfront to install.

No furnace can be 100% free of problems, however. In this post, we’re going to look at what you can do if your electric furnace begins to lose its heating ability—or it stops heating altogether.

Why Your Furnace May Be Short-Cycling

Friday, December 1st, 2017

Short-cycling refers to a problem that may occur in both heating and air conditioning systems: the unit starts to heat/cool, but shuts off too soon and doesn’t complete its cycle. A short time later, the unit starts up again, only to shut off once more… and the process repeats and repeats.

What Are the Risks of Delaying Heating Repair?

Saturday, November 25th, 2017

The winter is almost here in Virginia. That can mean some rough times outdoors and some cozy times indoors. However, you can be in for rough times indoors as well if you don’t schedule the necessary repairs for your heater right now. If your heater is currently developing troubles or is sending signals (like odd noises and uneven warmth) that something is amiss, you can’t hesitate and hope the problem will improve on its own.

If you need heating repair in Arlington, VA, call OASIS Heating, Air Conditioning & Refrigeration, Inc. as soon as you can. We have 24-hour emergency service!

Here’s what you risk when you delay repairs:

A single malfunction in your heating system will cause the entire system to work harder. A broken fan belt in a furnace, a leaky refrigerant line in a heat pump—these will make the heater strain to reach its target temperature, and that means additional wear and tear that could lead to a full breakdown.

And you know when that full breakdown will occur? On the coldest day of the year. This isn’t a case of Murphy’s Law at work; it’s mechanical logic. Your heating system will have to work hardest for you on the coldest day of the year, and that’s when the strain from lack of repairs will cause it to break. You don’t want to be stuck with a frigid house on a day when HVAC specialists are already scrambling to answer other emergency calls. You may end up with a long wait.

Delaying repairs usually means the repairs will be more expensive further on. Malfunctions won’t fix themselves: they will get worse from the heavier wear. By the time you do get around to scheduling repairs, two other malfunctions may have also occurred because of neglect.

Putting off repairs will cost you in another way: elevated energy bills. If your heating system is straining to reach its regular temperature, it will drain additional power—and that will show up on your bills.

Prompt repairs—and regular maintenance—will fix this

You should do more than schedule repairs the moment you know you need them. You should also enroll in a regular preventive maintenance program. A dependable HVAC contractor like OASIS Heating, Air Conditioning & Refrigeration, Inc. will offer programs that provide you two check-ups and tune-ups a year—one for your heater and one for your air conditioner. These visits will fend off repairs and breakdowns, as well as give you the most efficient heating performance possible.

When it’s time for maintenance or heating repair in Arlington, VA, contact OASIS Heating, Air Conditioning & Refrigeration, Inc.
