Learn How To Fix Frozen Up Air Conditioning

There are few things better than entering a cooled down home on a boiling hot summers day. But what do you do when your air conditioner starts freezing up? How can you fix it? And can you prevent it from happening in the first place?


Check the Refrigerant Charge


When your air conditioners refrigerant charge is lacking fluid or altogether charged improperly, the entire unit may freeze up and stop working. So, when your air conditioner is suddenly freezing up, one of the first things you should do is look for leaks. Leaks can be caused by a number of things, including loose parts scraping against each other and loosening joints and fittings which allow fluid to leak out.


Thus, when you notice that fluid is running low, call a technician who can fix up leaks and refill the charge. Once that is done, they will also be able to provide you with a general maintenance of your unit so future leaks and freeze ups can be prevented.


Check Up on The Airflow


In order to keep the air in your home clean and your unit running, your air conditioner has a built-in filter. This filter will catch particles such as dust and pollen, which would otherwise clog up the AC’s parts and infiltrate your home. However, if you neglect to change the filter when needed, the air can become too dirty for the filter to keep up with, which means dirtied coils that will eventually stop working and cause the unit to drop in temperature until it freezes up completely.


This issue is easily prevented by changing the filter on a frequent basis. A recommended time frame is often given in the manual, but the make and model of the filter itself can also influence how frequently it needs to be changed. Simply check in with the manuals and stick to the given schedule. It is important to call in the HVAC experts in Philadelphia to look over the requirements.


Remain Mindful Of Outdoor Temperatures


While there are things that can happen to raise the indoor temperature even while it is cold outside, there are limits for what your AC can handle. Your workout may have warmed you up, your cooking or baking may have brought sweat to your brow, but when the outside temperature is below sixty degrees, you should never switch on the AC. Your air conditioner unit will likely freeze up under such conditions, simply because they aren’t built to work while the outdoors is so cold. When switched on, the below sixty degrees air from outside will wash across the unit’s coils and cause them to freeze.

How Does Air Balancing Work?

The basic purpose of air balancing is to measure how well your HVAC system performs its duties, and while there are multiple ways to carry out air balancing, today we will focus on just two of them: Certified Air Balance, and Comfort Balance.

 


Let’s take a look at Comfort Balance first. As the name would suggest, with Comfort Balance we take a look at the level of comfort the conditioning brings to a room. How strong is the airflow? Do registers need to be added or removed, or simply adjusted? The circulation of the air will ultimately decide whether there is a problem with your unit or if all is working as it should.


Next, we have Certified Air Balance. Unlike Comfort Balance, this form of inspection will take a closer look at the unit itself, and will often be performed with newly purchased or built homes, or with other large-scale projects. Throughout the inspection process, the system’s capacity will be tested to ensure that all parts are compatible, and the overall performance is optimized for the building’s layout.


Certified Air Balance inspection goes something like this:

  • The HVAC Contractors in Philadelphia will research local regulations and AHRAE standards, and ask about your needs. Based on these details, they will then utilize their experience and training to draw up a detailed plan of the air conditioning system, including ducting, registers, requirements for the ventilation, exhaust vents, air flow, and the overall performance of the unit.

 

  • Blade dampers will be fastened to each duct branch, and behind the intake and exhaust openings.

 

  • An air balance technician will be brought in to replace filters and open up each damper before a reading is performed on all openings on the roof and inside.

 

  • With everything now optimized, all devices and dampers can be locked in order to fix the settings.

 


It should be noted that, even once locked, the occupants of the building can mess with the settings, should they neglect to replace dirty filters, drastically change the indoor layout, or otherwise mess with the factors which were considered during the optimization process. Questions and concerns in regards to your air conditioner, or air balancing specifically, can be directed at AC professionals in your area. If given the opportunity, they can come in and thoroughly inspect your unit to ensure everything is working as it should.


It is important to have the right professionals do the required services because they are licensed, insured and bonded. Apart from having years of experience, the HVAC contractors have the skill and knowledge to handle varied size units. If you have questions or queries, give Affordable Fixes LLC a call today.

How Can HVAC Duct Sealing Save You Money?

If you have been dealing with high energy bills, you may want to consider duct sealing. It’s a simple adjustment to make for the specialist who cleans your air ducts, or really just any AC service provider, and it can save you a lot of money in the long run, among other considerable benefits.


How Duct Sealing Can Increase Your Safety


With so many appliances in our homes that produce combustible gases, there is an ongoing risk of carbon monoxide poisoning and other threats that many of us live with. One single leak is enough to cause back drafting which describes the situation in which gases are pushed into your home instead of outside. When ducts are sealed, they are made to lead gases outside and away from anyone who could be endangered by them, including you, your family, and your pets.


How Duct Sealing Makes Your Home More Efficient


When ducts have leaks, the rest of the unit will require more energy to continue to function as needed. As a result, your bills will increase and your systems will be working overtime. Duct sealing has been documented to increase efficiency by a maximum of twenty percent, while also decreasing the risk of your home contracting mildew or mold.


How Sealing Ducts Will Improve Air Quality


When a duct is leaking, it allows for pollen, pesticides, car exhaust, and other harmful particles to freely enter your home, and as a result, your lungs as you breathe. By sealing air ducts, you will keep these harmful particles out of your home, where they belong. However, it is equally important to keep the ducting clean with regular maintenance. You might want to call in the experts to look at the various aspects of the ducts, if there is any infiltration of odors and smells inside the house.


How Sealing Ducts Increases Your Home’s Comfort


Leaking ducts will cause cool spots and hot spots all over your home, since optimal air circulation is impossible, when the system isn’t working as it should. Sealed ducts will allow for an even distribution of air and keep your home at an even temperature of your choosing.


How Duct Sealing Can Help Protect the Environment


Since sealed ducts are more energy efficient, they will require less fuel to work at optimal capacity. As a result, your home will cause less pollution, and thus decrease your influence on matters such as acid rain and global warming. Sealing your ducts is another step toward minimizing your carbon footprint. Call in a HVAC professional in Philadelphia PA today to check your air ducts for leaks so you can reap the benefits.

What To Do When Your Heat Pump Refuses To Work?

When your heat pump suddenly stops working, the best thing to do is, of course, to call a repair service. Specifically, a heating repair service, so they can send someone to come in and take a look at the heating system in question.


After all, a heating pump is complex in nature and an untrained person will not be able to spot the source of the problem. Once the contractor has arrived, you will be asked a series of detailed questions so be prepared to take some time out of your day to assist the contractor in their repair services. These are the most commonly documented heat pump malfunctions:


Outdoor Compressor And Fan Have Stopped Working


When the outdoor unit stops working, it is often due to a tripped breaker circuit, problems with the wiring, a blown-out fuse, a bad transformer, or an overloaded compressor. When this happens, you should pray that all you need is a furnace tune up, because the worst-case scenario would be the need for a whole new heat pump.


Humming Heat Pump That Won’t Start


The majority of the time, this is caused by a malfunctioning part, i.e. a bad start capacitor, compressor bearings, or compressor motor. Sometimes the cause will also be electrical problems. Regardless, you will likely need to replace the heat pump, unless the problem is electrical in nature, in which case the contractor may have a chance of saving it.


Outdoor Compressor Won’t Work


So, the compressor doesn’t work but the fan does. This is often due to improper phasing, poor voltage, a grounded compressor motor, or because of a bad capacitor. When it comes to such problems, it will be up to your contractor to determine whether your system needs replacing or if a repair job is sufficient.


Outdoor Pump Or Fan Aren’t Working


When there is an issue with the pump or fan relay, an issue with the timer, or a fault in the motor, then there is no getting around replacing the pump. However, if the issue is electrical, a straight up rewiring may get the job done.


However, don’t try to do it all on your own but call in the AC Repair experts in Philadelphia. They understand all aspects of the pumps and HVAC units and will be able to do what is necessary which will make sure that your unit is working again.


Indoor Fan Has Stopped Working


When there is a malfunction with the motor or transformers, you will not get around purchasing a replacement. However, if the problem is a blown fuse, bad circuit, or an issue electrical in nature, you will be fine with getting a repair job done.

Understanding the Importance Of Attic Ventilation During The Cold Season

If you wish to keep your home warm and protected throughout all of winter, you will need to have an attic in it that is properly ventilated. Lack of attic ventilation can lead to moisture build up which damages the very foundation and structural integrity of your roof and can bring along an urgent need for costly repairs. Additionally, proper ventilation will also allow for quality air flow throughout your home during the cold season. This is important to have fresh air while maintaining comfortable temperatures inside the home.


Benefits Of Attic Ventilation


There is an array of reasons as to why you should ensure proper ventilation of your attic, including the prevention and protection against:

  • the appearance of and spread of wood rot
  • popping roof shingles
  • the buildup of ice dams
  • the growth and spread of mold
  • moisture build up
  • frost build up


Since hot air rises while cold air sinks due to the differences in density, your attic will experience an increase in warmth during winter in contrast to the lower floors of your home. However, with the heat also comes moisture, at least it does when your attic space is lacking proper ventilation. And this moisture is then free to be soaked up by your home; it seeps into the materials which make up your roof, it seeps into the framing of your attic, it seeps into the boxes and furniture stored in your attic. In short: it brings mold and rot.


So how can proper attic ventilation fight this? Well, the installation of a ventilation system will lead to cool and dry air being pumped into your attic from the outside, while also transferring the warm and moist air from indoors to the outside. As a result, temperatures will remain even and moisture doesn’t get to build up. No more hot and cold spots. No more ice dams. Additionally, you will have turned your home into an environment protected against the growth of mold and mildew, as well as an environment unfriendly to rodents and insects. Calling on HVAC service in Philadelphia is important as they understand all aspects of the heating and cooling systems. Most of the companies offering these services have been in business for years and can offer regular maintenance and emergency services as well.


Understanding the Different Forms Of Attic Ventilation


It is recommended to have one square foot of ventilated space in contrast to roughly three-hundred cubic feet of regular, unventilated attic space. Additionally, you will also need an equal amount of intake and exhaust vents, in order to ensure functional airflow in and out of your attic.

Threat Of Refrigerant Leaks Throughout The Cold Season

All across the country, both businesses and homes depend on heat pumps to stay warm and functional throughout the cold season. Heat pumps function by transferring refrigerant through pipes in order to keep the indoors heated. Refrigerant works by changing its aggregate state between liquid and gas throughout the different stages of the heating system. However, due to these states of matter, refrigerant can also escape if a leak occurs in one of the system’s pipes. And such a leak can be more than just annoying. It can be dangerous. Especially if it occurs during the cold season.


Refrigerant Leaks During The Cold Season


Should a leak occur in a refrigerant line of your heat pump system, especially during the winter, you may be faced with disastrous consequences. Consequences that do not just impact your heating system, but may also pose a significant threat to the inhabitants of the home itself.


A sudden lack of heating, especially during dangerously low temperatures, can cause damage to property, but more importantly, pose a threat to the health and safety of people. Should a situation like this occur, it is vital to have a backup or auxiliary heating system to fall back on. It should be noted that it does not take something as severe as a leak to require the switch to the backup system. Simple inefficiency of your heat pump system is reason enough. The switch from the heat pump system to a backup is easily achieved by selecting the “backup” or “emergency” setting on your thermostat.


However, if a backup heating system is inaccessible or non-existent for you, you will need to get your refrigerant leak patched right away. No procrastinating. No evaluating. Contact a heating repair contractor as soon as possible so your refrigerant can be charged and your heating restored before temperatures become dangerously low in your home. Not only will that lead to uncomfortable temperatures but you can catch a cold and fall sick.


The Dangers Of Refrigerant Leaks Throughout The Cold Season


A sudden lack of refrigerant will cause a steady decline in the efficiency of your heating system, which in turn will cause a drop-in temperature in your home. Additionally, other malfunctions are also at an increased risk of occurring. Among these potential malfunctions are a frozen over heat pump and an overheated compressor which can permanently damage your system. Fixing such damage may require not just repairs, but full replacement. That is when you need to contact a HVAC service in Philadelphia PA so that they can offer you the best deal and subscription to maintenance services.

Benefits and Downsides Of Underfloor Heating

Over the course of the last few years, hot air systems and underfloor heating have slowly begun to replace radiators and fireplaces. This is largely due to the decrease in utility bills it brings. However, as with everything else, there are benefits and downsides that come with the installation of underfloor heating. Benefits and downsides which we are going to explore in the article below, so read on if you are curious.

The Two Basic Types Of Underfloor Heating

The market currently provides us with two main forms of underfloor heating; one making use of warm water pumped through pipes, the other making use of electric coils. While mainly affiliated with high end establishments like hotels and resorts, these systems can also be installed by a Heater Repair Service in Philadelphia PA in regular homes.


Warm water underfloor heating requires the installation of an interconnected series of pipes which starts at your home’s boiler and webs along below the floorboards of each room you wish to heat this way. While this form of underfloor heating requires lower temperatures than the other, electric, system, it is also costlier to install due to the more elaborate process of the installation itself. Additionally, the floors of the rooms may need to be slightly raised due to the thickness of the pipes.


The other option would be electric underfloor heating, which requires the installation of a web of wire coils below the floorboards of each room you wish to heat this way. You may also be able to opt for heat mats in certain rooms, though uncommonly shaped rooms will require individual wires if you wish to cover the entirety of the room. Additionally, you will also need insulation below the wires. While electric underfloor heating is cheaper to install, it should be noted that it cannot be installed under carpeted floors.


The Benefits Of Underfloor Heating


A lot of people choose underfloor heating to rid themselves of the constraints set by radiators which require to be free of furniture to heat the room. Additionally, radiators will also spread heat unevenly due to their location, and require more electricity to function in lower temperatures. In contrast, underfloor heating is more efficient in both operation and operating costs.


The Downsides Of Underfloor Heating


The lack of underfloor heating in regular homes can be traced back to three main reasons: installation costs, incompatibility with older buildings, and slower heat up time. You can always call on reliable HVAC contractors that have ample experience and expertise in handling such cases. If the underfloor heating system is old, they can remove and install a new one with ease.

A Guide To Charging Heat Pumps During The Cold Season

Refrigerant is a substance (or mixture) that is used to move heat back and forth between the in- and outdoors. However, since refrigerant is transferred through pipes, these lines may be damaged, which will lead to leaks, and thus a loss of refrigerant. As a result, the heat pump requires a recharge in order to restore the desired performance level.


The Complexity Of Charging Your Heat Pump During Winter


If you wish to, or need to, charge your heat pump in the depths of winter (or generally low temperatures), you will need to make use of what is called the “superheat method”.


This method can only be performed by HVAC Repair technicians in Philadelphia who have undergone the required training. “Superheat” is a term which is used when talking about the differences in temperature between refrigerant vapor in its actual state and refrigerant vapor’s temperature during saturation.


If you wish to keep your home warm and cozy, your auxiliary heating system needs to be up and running during the repair process of your heat pump. This is because the heat pump needs to be offline while the necessary repairs are made.


The charging process of a heat pump is significantly more difficult during the cold season due to the latent heat load being so minuscule around the evaporator.


Additionally, and as a result of this, the refrigerant charge of your heat pump cannot be perfect, but it will still be more than enough to restore efficiency to your system.

Charging Process In Low Temperatures

  • In order to keep the air inside the system from escaping, the condenser will be covered by a sheet of plastic.
  • Using the 4-way reversing valve, the heat pump’s mode is switched to cooling. To achieve this, its low voltage wire will need to be removed. This is because the thermostat will still be asking for heat which it will now be able to obtain through the auxiliary heating system. Once this set up is complete, your home will remain heated, even while the heat pump is down.
  • The refrigerant vapor in the refrigerant lines needs to be retrieved by bleeding air from the lines.
  • In order to capture this refrigerant, a refrigerant cylinder will be fastened to the gauge lines and switched upside down. Once this set up is established, the manifold valve can be opened and refrigerant liquid can be retrieved.

 

It is important that you discuss the details with a reliable and licensed contractor that has years of experience in handling varied sizes of HVAC systems. Usually, such services offer standard maintenance plans on a regular basis.
