We’re starting to experience colder and rainy weather as we head into the final month of the year. Do you have confidence that your heating system will be able to work at its best through the coming winter? No matter your answer to that question, if you haven’t scheduled a professional inspection or tune-up for your heater, now is the time to take care of it. It isn’t too late!
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.
The summers in Virginia can grow extremely humid, and everyone knows the unpleasant experience of a hot and muggy day. The installation of a whole-house dehumidifier is a good way to balance humidity inside a home and eliminate the extreme discomfort of high humidity.
But what about installing a humidifier? Are there times when raising the humidity inside your home is a good idea? The answer is Yes, as we’ll explain below.
Although the storage tank water heater is the most common way for homes to receive the hot water necessary for daily chores, the tankless water heater is gaining rapidly in popularity. If you have a tankless water heater, than you probably can’t imagine switching back to using an old tank model. After all, a tankless water heater uses much less energy, it never runs out of its hot water supply, it takes up 80% less space, and it lasts for many years longer with far fewer repairs than a standard water heater.
Hybrid heating refers to heating that uses two or more types of systems to perform its duties. You most often see hybrid heating as a means of augmenting a heat pump, which is commonly used in Fairfax, VA heating systems (as it is in other cities throughout Virginia). Heat pumps combine the features of heaters and air conditioners, using the same basic system to cool your home in the summer and heat your home in the winter. Heat pumps work best in areas where the temperatures stay above freezing. When it gets especially cold, however, a heat pump will no longer heat efficiently, which is why households in this area usually augmented it with a smaller electric or gas furnace. Hence the term “hybrid heating system.” But what’s so special about hybrid heating?
In the first place, hybrid heating is an all-in-one option which can handle your whole home no matter what the weather. Our summers can be as warm as our winters are cold, and hybrid heating makes it easy to keep your house comfortable. Furthermore, they’re safe and reliable forms of technology, able to effectively heat or cool your home with a minimum of fuss and bother.
Perhaps most importantly, hybrid systems save you money. When the temperature is cool but not cold, the heat pump can do the job much more efficiently than a regular gas furnace could alone. On those super-cold days, the gas furnace can kick in and heat your home. Hybrid heating systems can offset the cost of installation through such savings, as well as improving the resale value of your home.
Life every other HVAC system they do still need maintenance from time to time, and you’ll want a qualified technician on-hand to perform the installation. For any Fairfax, VA heating issues, Oasis Heating, Air Conditioning & Refrigeration Inc. is here to help. We can explain what’s so special about hybrid heating, then set up an installment and maintenance plan that works for you. Pick up the phone and give us a call today!
Having to schedule heating repair isn’t at the top of anyone’s list, but when it comes to your business, it’s essential that your heating system work as needed. It can be very tempting to wait on repairs, especially if your system is still running, but as we’ll explain below, this is not a good idea. It also isn’t a good idea to call just heating repair business to perform the commercial heating repairs you need in Alexandria. The best way to ensure that your commercial heating system is properly, accurately and efficiently repaired is to hire commercial heating repair specialists, like the ones at OASIS Heating, A/C & Refrigeration, Inc. Our NATE-certified commercial repair experts are available 24/7, so if you are experiencing an issue with your commercial heating, call us today.
Reasons to Call for Repair
Here are some reasons why it’s better to call for repair sooner rather than later:
You may end up with no heat – heating systems tend to breakdown on the coldest days of the year because that’s when they work the hardest; a system that is already stressed due to repair will be more prone to total breakdown than one that has been repaired.
Repairs will get worse – repairs do not fix themselves, and typically become worse over time. This can result in bigger, more costly problems and potential breakdown.
Decrease in energy efficiency – a stressed heating system has to work harder to achieve the temperature set on the thermostat. This can result in more energy usage, which decreases your energy efficiency.
It could be dangerous – combustion heating systems can develop leaks that release toxic fumes and gases; allowing a malfunctioning heating system to continue to operate could put you and your business at potential risk.
Decrease in overall performance – allowing a malfunctioning heating system to operate only contributes to running down the system. As a result, you may see a decrease in air flow, an inability to achieve the set temperature and other problems that can directly affect your business.
Don’t let your business space suffer from a malfunctioning heating system.
The purpose of a household heating furnace is to warm your living quarters on an as-needed basis. As such, a furnace that is not blowing air through vents across your heating system is indeed problematic. Likewise, a furnace that is not blowing air in one room is a confusing issue that could stem from various factors, all of which require immediate attention.
Is a Furnace Supposed to Blow Air?
A furnace consists of a motor fan that blows air across heating coils, thus warming the air. This warm air is dispersed through the ducts of a household heating system to bring occupied living areas to the desired temperature. The furnace runs until the preset maximum temperature — usually at an owner-programmed level, such as 70 degrees Fahrenheit — has permeated the household interior, at which point the furnace shuts off to save energy.
Therefore, a furnace is built to blow air, but only warm air. A furnace blowing cold air is indicative of a problem. Funny as it may sound, a system set to “on” will not necessarily blow warm air. This is due to the programmed settings of a furnace system, which gauge the temperature within a living quarter and only disperse heat until the preset temperature is reached.
For example, if you have your furnace set to 70 degrees Fahrenheit, the furnace will shut off the heating coils once the ducts sense an ambient room temperature of 70 degrees Fahrenheit, but the fan will continue to blow cold air if it is set to “on” instead of “auto.”
How to Tell If Your Furnace Is in Trouble
If your furnace is on but no heat is coming forth, the problem could stem from issues with your thermostat. If your furnace is not blowing heat or even seeming to activate, you have a more serious problem at hand. Watch for the following tell-tale signs of furnace trouble:
Furnace Blows Nonstop
As outside temperatures drop, the confusion that the furnace-or-fan issue can cause is liable to be quite frustrating. If you constantly hear the sound of a blowing fan yet do not feel the level of warmth that you would expect from a furnace, you literally do have a case of cold air. Simply put, if the settings on your furnace system are not properly coordinated with the fan, the latter will blow irrespective of whether you need or want actual heat.
Furnace Not Blowing Hard Enough
If the furnace blowers are generating heat in insufficient quantities, the issue is likely due to either a dirty motor or a loose blower belt. The motor can accumulate dirt over time and the gradual buildup can wear down the system. This impacts the ability of the furnace to deliver heat on a consistent basis. Likewise, a worn belt could deprive the furnace of its proper rhythm and cause the heating mechanisms to drag or work in fits and starts.
Furnace Turns on but No Heat
If you feel no heat in the minutes after you activate your furnace, something could be wrong with the belt, heating coils or furnace settings. If the blowing mechanisms are inconsistent or non-functioning, there is probably an issue with the blower belt. If the blowers are working as normal but you feel no heat, the issue is probably due to the temperature settings or heating coils. The settings can easily be adjusted if you need to test the performance of the furnace but an issue with the heating coils will necessitate a call to your nearby HVAC service specialist.
Cold Spots in Home
If it seems that your furnace is only blowing air in certain rooms despite a well-dispersed heating system, chances are the furnace has not been activating with the same consistency as before. Perhaps the furnace ducts sensed the wrong ambient temperature within your house and deactivated prematurely? Or perhaps the time/day settings are being misread by your furnace system. Either way, you are liable to experience inconsistent indoor temperatures if a misreading of any kind occurs in your furnace system.
Reasons Why Your Furnace May Not Be Blowing Air
An electric furnace that is not blowing air could be the result of various problems. With so many complex mechanisms involved in a heating system, any given number of issues could cause the furnace to malfunction. Furnace problems, from minor to severe, generally stem from one of the following 10 issues:
The Temperature Is Incorrectly Set
In a multi-person household, there are liable to be different views regarding desirable indoor temperatures. For example, one person’s “warm” could be another person’s “chilly.” Disagreements like these often go un-discussed, even between married couples. Consequently, a thermostat might be turned down at some point during a given day, yet the action remains unbeknownst to the rest of the occupants.
If you live in a household of two or more people, call everyone together for a discussion about mutually agreeable indoor temperatures throughout each period of a typical day. Moreover, check the temperature settings of your thermostat to make sure that the numbers are what you intended, especially if you feel colder than expected and you suspect that the settings might have been altered without your knowledge.
The Furnace Is Not in “Heat Mode”
One of the more elementary oversights that homeowners make is to activate the furnace but leave the thermostat in air conditioning mode instead of heat mode. Thing is, a lot of homeowners overlook these setting options and go about not knowing that the mode is wrong. The confusion is due, in part, to the increasingly complex nature of today’s programmable thermostats, which offer an array of options that make it possible for users to confusingly misprogram their systems in various ways.
Your DIY Thermostat Installation Went Awry
If you have recently installed a new thermostat on your own, it is quite possible that the installation did not take as well as it appeared. Even if you followed the directions, there is a strong likelihood that certain adjustments are needed that can only be performed by an HVAC service specialist.
Alternately, it is possible that the thermostat you chose is simply not compatible with your pre-existing heating system. Situations like these have become all-too-common as the market is flooded with fancy self-install thermostat kits that are incompatible with older household heating systems.
The Date and Time Are Incorrect
If you are not getting the temperatures you expect, the problem could be due to the day and time settings on your thermostat. Homeowners with programmable thermostats often go about not knowing that the hour and day settings are way off.
For example, it might be 8 p.m. Sunday in your area, but your thermostat believes that the time is actually 1 p.m. Tuesday. Consequently, the thermostat thinks that you are at work instead of home reading a book. To save energy, the thermostat sets the temperature low. After all, you wouldn’t likely need the house warm during the afternoon of a typical workday.
The Battery Is Dead
When the date and time are improperly set, the issue often stems from dead batteries in the thermostat. Without battery power, the thermostat has to rely solely on the power supply of your house. Consequently, the thermostat settings will reset following a blackout or brownout, whereby the time and date default to 12 a.m. Sunday following a mid-week power outage. In some cases, a thermostat will dump its settings when the battery runs low.
You could easily go several months not knowing that the time understood by your thermostat is four days and 18 hours behind the actual date and time in your area, all because of a dead battery. Meanwhile, that same period could see your heating bills increase as you crank the heat to overcompensate for the lack of warmth from your furnace.
The Circuit Breaker Is off
Some of the more complicated furnace issues involve the circuit breakers. A heating system will have one or possibly two or three different circuit breakers, any one of which could trip and cause the furnace to stop. For example, if the circuit breaker to the furnace is off, the furnace will not generate heat. Likewise, if the circuit breaker to the blower fan is off, warmth will not be spread from the heating coils.
If tripped, circuit breakers should not be tested more than once. An issue of repeat tripping should be reported to an HVAC service person immediately.
The Filter Is Clogged
A clogged furnace air filter can cause two types of problems, one involving blocked airflow and the other concerning tripped shutoff functions. In some cases, the buildup of dust and debris can thicken to the point where the passage of warm air is blocked by the filter. Therefore, while it might seem as though the furnace is not blowing air, the only real problem is that the furnace needs a new filter.
The second, more common problem that arises with clogged furnace filters is when the restricted airflow causes the furnace itself to overheat and trigger the system’s safety shutoff. Thus, while you are left with the impression that the furnace won’t blow heat, the furnace has actually overheated and stopped due to a clogged air filter.
The Blower Fan Is Not Working
If the furnace isn’t blowing air with any degree of warmth — and the thermostat settings, circuit breakers and air filter have all been ruled out as possible causes — the problem could stem from the blower fan itself. The function of the blower fan is to blow air across the furnace’s heating coils and disperse that warmth through the air ducts. If the blower fan stops working, you have a more serious problem at hand.
You can test the blower fan by turning off the heat — or, depending on your system, setting the thermostat to “fan only” mode — and switching the fan from “auto” to “on.” Wait for a few minutes to see whether any fan breeze comes forth.
The Limit Control Switch Is Damaged
In a household heating system, the limit control switch — alternately known as the fan limit switch or furnace fan control switch — controls the automatic on/off functions of the heating coils and fan. If you turn your furnace off or the room becomes sufficiently heated to the point where there furnace halts automatically, the limit control switch shuts the blower off to save energy. Likewise, when the heating coils warm, the control switch kicks the blowers on to disperse the heat through your household air ducts.
If your furnace does not seem to be working, the limit control switch could be responsible in one of two ways. If the furnace overheats, the control switch will shut off the system as a safety precaution. This could be due to an overheating issue but it could also stem from a misreading on the part of the limit control switch. In the latter scenario, you probably have a damaged limit control switch.
The Heating Coils Aren’t Functioning
Beyond any possible issues with the blower fan, the most serious problems with a furnace are those that stem from the heating coils. If the coils are faulty, no thermostat settings, clean filters or switch adjustments will do the trick. If you have ruled out all the previous possibilities and even replaced the limit control switch, only to find that the blower fan still switches off, there is something wrong with the heating coils.
There are a few steps that homeowners can perform to determine the source of a furnace problem. If the issue is minor, it can sometimes be fixed singlehandedly. In other cases where serious problems are involved, professional service is necessary, especially when a gas furnace is not blowing air. In any event, check the following:
Check the Thermostat
Before you declare any serious problem with your furnace, check the settings on the thermostat to see whether everything is set to the desired modes and levels. Given the possibility that someone else in your household might have changed the thermostat setting, check to make sure that the thermostat is set to “heat” instead of “cool.”
To test the quality of the heat itself, raise the thermostat temperature by five degrees and wait for the system to activate. Do you feel warm blowing air? If the batteries are old, replace them — remember, if the time or date settings are off, the battery is likely dead. Also, clear away dust from under the thermostat panel.
Check the Air Filter
The air filter is one of the more obvious parts to check since it is easy to see how a clogged filter would impede the flow of air from a furnace. In a sense, it is like the lint trap in a laundry dryer, which needs to be cleared between each usage cycle. With your furnace filter, do an inspection every three months and replace the filter if dirt buildup has taken hold.
Prior to accessing the air filter, shut off the furnace and thermostat.
Check the Gas Supply
If you have a gas furnace, check the gas supply to see whether the fuel supply is sufficient. Also, check the gas valve to make sure that it is set to “on.” Every now and then, a gas valve is accidentally left off after a round of maintenance and others in the house are confused when the furnace does not work as expected.
If you discover a gas leak, turn off the gas valve and all the switches to your heating system and report the issue immediately. Do not light any matches or lighters near the furnace. Gather everyone in your household and exit the premise until help arrives.
Check the Pilot Light
Pilot lights are used on older, pre-electronic ignition gas furnaces. If the pilot light fails to remain lit, the problem might stem from a clogged orifice, which can be poked clear with a small piece of wire. Before you try this step, turn off the furnace and shut off the circuit breaker.
