No Cool Air? A Frozen Coil May Be the Cause

Warmer weather will be here before you know it, and your air conditioner will be working hard to keep your home cool and comfortable. Over cooling season, you may run into a common air conditioner repair issue – a frozen coil.
Learn why air conditioning coils freeze up, their signs, and what to do to solve this problem and restore cooling to your home.

Why Do Air Conditioning Coils Freeze?


Air conditioners need good airflow moving through the equipment to keep coils warm and working correctly. When air isn’t freely moving across the evaporator coil, its temperature drops, leading to a frozen AC coil. A dirty air filter or restricted air movement in ducts could be preventing proper airflow.

Air conditioners require correct refrigerant levels to operate. When a refrigerant leak is present, refrigerant pressure drops while the system requires the same level of expansion. This creates a cooler temperature, dropping the coil temperature so it freezes.

All sorts of mechanical problems and other issues can cause an air conditioner’s coils to freeze. Moisture that is condensed by the cooling process freezes due to the coil’s low temperature before it can drain away, creating the ice you see on your cooling coils. This ice acts as an insulator, preventing the heat transfer that creates cooling.

Signs of a Frozen Air Conditioning Coil


If your air conditioning coils have frozen, you may experience the following symptoms:

  • Air conditioner runs, but no cool air comes out in your home.

  • There is visible ice on your indoor or outdoor coils.

  • There is more condensation in your home or around your cooling unit, as frozen cooling coils create moisture buildup.

Correcting Temperature Variations Throughout Your Home

Most homes have them – the room you know as the “cold room” or “hot spot.” It doesn’t matter what you set your thermostat to, these rooms don’t budge on comfort and always feel cooler than your other living areas in the winter. In the summer, this spot is noticeably warmer than the rest of your home.

Constantly adjusting your thermostat settings in attempt to make every room comfortable is an obstacle, but don’t worry – temperature variations, notably in older homes with poor insulation and thin walls, are quite common.

Why Do Temperature Variations Occur?


Temperature variations in the home are caused by various factors. A room’s location has a lot to do with it. If the room in question is located farthest away from your heating and cooling system, not as much airflow may reach it as compared to closer areas.

In the winter, you may be unknowingly letting cold air into the room, contributing to the temperature variation you feel. Windows and doors with cold outdoor air blowing in need gaps caulked and worn-out weather-stripping replaced. Upgrading to energy-efficient windows will help keep temperatures balanced throughout your home.

A room’s size has a big impact on maintaining comfortable temperatures. It’s more difficult to keep temperatures balanced in a larger space. Rooms that have all-day sunlight exposure likely feel warmer than rooms that are dark. Opening the shades and blinds in rooms during the winter allows the sun’s warmth to seep in. Over the summer, utilize sunscreens or keep blinds closed to maintain a room’s temperature.

INSTALLING DUCTWORK IN AN OLDER HOME

Owning an older home can be a joy for many homeowners. The sense of history and timeless design are just some of the reasons you may want to buy an older home. One common drawback is the installation of a central heating and cooling system, something not typical when the house was built. Where the issue arises is in the installation of ductwork into an older home. The reason for this is that older homes were not designed with ductwork in mind. This makes for an installation process that requires careful planning on your part. However, despite the hurdles, it is entirely possible to the process of installing ductwork come to a successful conclusion. What follows is a brief overview of different methods of installing ductwork and general advice on how to approach an installation.

THE DRAWBACKS OF TRADITIONAL DUCT SYSTEMS

The main drawback of traditional methods of installing ductwork is the lack of space. The installation of traditional ductwork in an older house is time consuming and requires a professional to perform an effective installation. Also due to the lack of room, in most cases the ducts themselves have to be installed in the closets. Do note that even with these drawbacks a traditional duct system can be every bit as effective in an older home as it is in a newer one. You have to be realistic about the logistics of the installation process. While this method of installing ductwork can be done by a professional, you may want to keep your closet space. If such is the case there are alternative methods of installing HVAC systems in an older home.

DUCTLESS, SPLIT-SYSTEM AIR-CONDITIONERS

A ductless, split-system unit can prove a useful alternative to a traditional duct based system. These units don’t require ductwork at all and offer several advantages, if you choose to make use of them. They tend to be quieter than normal units and they are easier to install and move around, offering for a degree of versatility in your installation. Due to their lack of ducts they tend to not lose as much cold air when in operation and they use less energy as well. The last advantage you may want to keep in mind is the versatility of usage a ductless system offers you. If you have a larger home you can install multiple units, allowing several different rooms of the home to be cooled individually. While they are highly useful split-system air conditioners have drawbacks as well. The focal issue is in terms of appearance, as they don’t blend into a home as easily as a central air conditioning unit does.

As you can see, even in an older home you have options when installing ductwork. The traditional methods can still be used, provided you accept the tradeoffs that go with installation. However, if you feel this is too much of a compromise split-systems offer an interesting and useful alternative. No matter which way you choose to approach the question of installing ductwork, you need a professional to assure the job is done right.

We can assist you in installing ductwork, split-systems, or repairing/replacing any existing ductwork you may already have. Call us today for a free estimate.

KNOW YOUR DUCTS


We’ve had a look at the different compressors and condensers used for central air conditioning, but what about the ducts? Simply put, a duct is the channel that carries cooled air from the air conditioning unit through your home, and can also remove warm or stale air. Ducts for central air conditioning can also be used for heating and filtering systems. Let’s look at some of the different types of ducts needed for air conditioning.

FLEXIBLE DUCTWORK

Flexible ducts are typically tube-shaped, made of a wire coil covered with a bendable, durable plastic, and surrounded by insulation. This kind of ducting is best in tricky spaces where rigid ducts are just not possible to install, or used to attach non-flexible ductwork to an air supply outlet. Like most central air conditioning parts, flexible ducts have specific installation requirements. For example, flexible ductwork needs to be secured and supported properly, ensuring little sagging or snaking. Kinks, bends, and turns also need to be minimized – these reduce air flow and could hamper the efficiency and effectiveness of the air conditioner. The advantages of flexible ducts are that they are fairly quick and easy to install, and often cost less than rigid ductwork. You can find out more about flexible ducts and their installation guidelines from the American Society of Home Inspectors.

RIGID DUCTWORK

They come in a variety of materials and sizes, and can be either cylindrical or rectangular. They are also often insulated. They are hardy, enduring, and reliable. The most common types of rigid ductwork are:

Sheet metal ducts. These are the kinds of ducts you’ve seen in films – usually with an action hero crawling through them! Galvanized steel and aluminum are the most common materials for sheet metal ducts. Aluminum in particular is relatively light and easy to install. They are also the least likely to harbor dangerous molds or growths because they have non-porous surfaces.
Fiberglass lined ducts. These are sheet metal ducts (like those described above) that have internal or external fiberglass lining. This type of duct is common in office and commercial buildings, as it dampens the sound of the air conditioner unit. However, the fiberglass in these ducts can deteriorate and eventually release fiberglass particles into the air – this is a major health concern, especially with long-term exposure. Fiberglass lined ducts are also difficult to clean for this same reason: the cleaning process can damage the lining and release fibers. These ducts can also become contaminated with molds and bacteria.
Fiberboard ducts. Fiberboard is made from fiberglass strands that have been compressed and bonded with a resin, and then covered with a sheet of foil laminate to protect them from moisture. This type of duct is good for cooling and heating systems because it is well insulated by itself. However, it’s not recommended for ventilation because, like fiberglass-lined ducts, they can become a breeding ground for mold and mildew in humid climates. Also, because the surface is rough, they can also affect airflow and efficiency.
When installing an air conditioning system, consult with your contractor to find out which type of duct is best for your home or office. More often than not, sheet metal is the safest and most effective material for creating ductwork.
