Why Is My Heat Pump Blowing Cold Air?

Monday, February 17th, 2014

Heat pumps are incredibly useful systems for providing year-round home comfort. They improve upon the concept of the air conditioner to use the same system of heat exchange to also provide warm air. It’s as easy as turning a switch to move from heating mode to cooling mode.

But what if one day your heat pump stops doing half its job? If it’s winter, and your heat pump starts to blow out only cold air, there’s something wrong that will require professionals to investigate and repair it. If you need this sort of work on your heating in Fairfax, VA, give the technicians at OASIS Heating, A/C & Refrigeration, Inc. a call, any time of the day or night.

Reasons your heat pump is staying in cooling mode

The most common reason for this occurrence is a problem with the reversing valve. This component is one of the key parts that differentiates a heat pump from a standard air conditioner. The reversing valve changes the direction that refrigerant flows through the heat pump, and this is what makes the heat pump switch from being an air conditioner to a heater and back. An electric charge to the valve controls whether it is in one mode or the other. If the heat pump malfunctions, it will remain in one mode until professionals come and replace it. Do not attempt to change a reversing valve on your own.

Another possibility for a heat pump remaining in cooling mode is a miscalibration in the thermostat or a thermostat malfunction. A miscalibrated thermostat may not know to turn the heating on because it is misreading the temperature. If trouble occurs in the thermostat wiring, the unit may lose its ability to signal to the heat pump to switch modes. Repair technicians will be able to quickly discover the source of the problem and fix it.

There are a few other possibilities that could result in a heat pump experiencing this trouble. Because of the complexity of a heat pump’s operation, you’ll need to have trained heating technicians examine the unit to diagnose the issue and how to target repairs.

Our trained repair staff at OASIS Heating, A/C & Refrigeration, Inc. is ready 24/7 for the repairs you need to keep your heating in Fairfax, VA up and running. Whether your heap pump is stuck in cooling mode or something else is stopping it from giving you the comfort you need, trust to our service to fix it.

Leaks in Radiant Heating Systems

Monday, February 10th, 2014

Radiant heating systems are a terrific option for home comfort that has spread from Europe into the United States and gained great popularity. Most radiant heating systems use hydronic (water) power to send heat through pipes under your floorboards and provide you with toasty warmth right under your feet. There are some electronic radiant floor systems that you can have installed as well.

But using hydronic power always comes with the risk of leaks developing. Modern radiant floor heating is built to resist leaks because they are fixed systems that do not permit oxygen to enter and degrade the piping. But leaks can still occur. When you need professional repairs, or installation, for your heating in Arlington, VA, contact our specialists at OASIS Heating, A/C & Refrigeration, Inc. Even if we didn’t install your radiant heating, we can repair it.

The most common cause for leaking to occur in radiant floor heating is from construction stress. When these leaks develop, they will usually start underneath floorboards or floor stones and will cause damage to building material. This is similar to what plumbers refer to as “slab leaks”: pipe breaks that occur under concrete, leading to extensive damage unless fixed.

When you suspect that you have a leak in your radiant heating system, you need professionals to perform leak detection to discover exactly where the water is coming from and how best to access the pipes and repair them. The precision technology used to locate leaks means that technicians can pinpoint the location so exactly that they usually need to do only a minimum amount of removal of floor material to access the leak.

Sometimes, radiant floor heater leaks do not require excavation in order to repair. An injection of a type of sealer additive into the water system can take care of minor leaks, and this will also prolong the life of the system.

If you have leaks in your radiant heating system, you will need repairs… fast! That’s why we offer 24-hour emergency service at OASIS Heating, A/C & Refrigeration, Inc. We know these problems almost never occur when it’s convenient, and we are ready to help when you need it. We can be there for all your troubles with heating in Arlington, VA.

Why is My Furnace Producing No Heat?

Tuesday, February 4th, 2014

Sometimes, a problem with your furnace can be very subtle, requiring a little detective work to successfully ferret out. A furnace that produces no heat, however, isn’t one of those cases. You pretty much know right away if no warmth is coming out of your vents, and a call to a qualified service technician is probably next on the agenda. If you need furnace repair in Arlington, VA, the experts at OASIS Heating, A/C & Refrigeration Inc. can resolve the issue properly.

You may be asking yourselves, “why is my furnace producing no heat?” – we’ve included a brief outline of the issue below.

A lack of heat stems from one of two basic sources: no heat being generated and no air being blown through the system. In the former case, there’s no heat being made at all. If the unit is one, it may indicate a problem with the burners (they may be clogged or otherwise inoperable), or it may be a problem with the thermocouple or ignition system. The thermocouple regulates the flow of gas into the furnace and if the pilot light is out or some other problem exists, it won’t release any gas to start the heating process. In every case such as this, a technician can solve the problem by cleaning, repairing or replacing the faulty part.

In the event that no air is being blown into the house, the technician can check the air filter or for a build-up of dust and similar particles preventing the air from flowing. The trouble might also be with the fan mechanism, such as a faulty motor or a misaligned fan blade.

Whatever the cause, OASIS Heating, A/C & Refrigeration Inc. hunt down the source of the problem and correcting it. Our trained Arlington, VA furnace technicians are on call to answer your questions and we conduct ourselves with your satisfaction in mind at all times. Call us today to schedule an appointment.
