Does air conditioning cause sore throats?

The simple answer is no. There may be a link between air conditioning and getting a sore throat but it isn’t a causation. Air conditioning can be a breeding ground for bacteria and for infestation but with these clever ideas on how to maintain the system, it should not be an issue.

Things to know about Air Conditioning

Like many mechanical systems, AC needs some TLC for it run smoothly and essentially last longer!

Filter changing

If the filter in your AC is dirty, the device will not be working as efficiently as it should be.
By installing a new filter once each month during the cooling season for the central units and window units, or wash them if they can be washed.
Another way of checking if the filter is working at its best is by checking the minimum efficiency reporting value (MERV), which ranges from one to twelve for home AC units – the higher the number, the better the filtration.

Fixing air leaks

It is possible for ducts to lose up to 30% of airflow through leaks, and in regards to a window AC, these are quite difficult to seal.
A way of discovering where the leaks are is by using the old ‘smoke trick’.
For window units, you could light a stick of incense and hold it alongside where the unit and the window frame meet, for a central AC, hold it near the duct connections, and if the smoke blows around – you have a leak.

To repair ductwork, an option is using foil tape to seal the smaller gaps, and for the larger gaps, duct mastic.
In regards to a window AC unit, foam should be stuffed between the device and window frame, then proceeded with a seal of tape.


Ducts that are situated in warm attics or crawl spaces must be wrapped in order to keep the air inside cool.
Spray foam, batt insulation or rigid foam insulation can all be used.
Batt and rigid insulation should be sealed with foil tape, and for tight spaces, a wrap similar to Reflectix will offer some degree of insulation.

Help it out

You can extend the life of your AC by helping it out a little as well!
Keep blinds and shades down during the day, and maybe consider running the AC in conjunction with floor or ceiling fans in order to circulate cool air effectively.

Don’t close rooms

Refrain from closing off interior doors as this can cause the central AC systems to wobble off balance, resulting in less airflow in the entire house.
Try and keep the doors slightly ajar instead.

What’s the best time of year to install Air Conditioning?

Air conditioning is installed thousands, if not millions, times a year, but when’s the best time to get it installed?

A question we always seem to encounter from those who are curious about installing air conditioning: What’s the best time of year to install air conditioning? Weirdly, the best time of year to get your home kitted out with A/C is winter! You’re more likely to get a better price on your air conditioner in the cold weather, as the slower season means that contractors have a lot of time to install in-between their repair service.

The Basics of Air Conditioning

What’s the basic of air conditioning? The meaning for air conditioning is simply what is sounds like: conditioned air. This means that the air has been cooled down and cooled down air has a lot of its humidity removed. The lower levels of humidity in conditioned air supply our bodies with the ability of perspiration much more effectively, which in turn allows us to cool down faster and more effectively. Many people believe that air conditioners actually produce cold air, when in fact they actually remove the heat from the air and push it to another place. In air conditioning units, an evaporator coil is responsible for removing any heat found in the air. When air flows through it, the heat is released elsewhere by a coil that condenses the air. In some split systems, the condensing coil is located on the exterior of the home, which allows for the dispossession of hot air more effectively.

Cooling your home

Having central air conditioning installed in your home may give a major benefit to your home cooling system. With the weather currently heating up and causing problems for people across Britain, so having a central cooling system in your home is vital. Central air conditioners are often more economical compared to having multiple units throughout your home, as having a unit work from one central position is way more energy efficient. Also, it eliminates the task of having to remove window units in the colder seasons. If your home is lucky enough to already have a central air heating system, having the remainder of the system installed is an easy job – as most of the air unit is already in place. If your home has a radiant or baseboard system, then you will need a higher level of A/C installation.

What are the costs of air conditioning?

Simply put, the price of air conditioning will change depending on who fits it and offers the service. The fitting of an older home can actually be a difficult task. If you’re not interested in taking out a central air system, you may consider the possibility of installing a number of fixed wall units which can reside in various rooms throughout the house. The wall units in question actually work a lot like window units, yet the need to install and remove these each season is eliminated, which makes this form of air conditioning a much more efficient service.

You should remember that you can change the design of your project in order to match the needs of your home, as this may also lead to more cost effective forms of air conditioning. Another good alternative to air conditioning are ceiling fans, as they are way more cost effective. Homes that are super insulated encounter lower levels of cooling requirements, so keep this in mind if your home is such a build.

New ducts

If your home is one that lacks a central forced air heating system, A/C can still be installed, it is just going to entail more work and expense. These costs will vary by the configuration of your home. Single story homes can be readily equipped from the attic, basement or crawlspace if present. Multi-story homes may need more complex ductwork to span the different levels or have redundant systems installed to be served from multiple areas. Obviously the more intrusive the work the greater the cost. The backs of closets often provide a “chase” that is used for running ductwork from a basement to a second floor. A large portion of the expense of these installations comes from new air-handling systems that are already present in existing forced air-heating systems.

Given that your home is lacking a central air heating system, air conditioning can be installed, it’s just necessary that more work and higher expenses will have to be taken. The costs on how much this will take depends on the configuration of how your home has its layout. Homes that have one story can have an A/C unit installed through the loft or basement, given one is present. Given that the home has two stories, a much more difficult system is required for install. The more intrusive the work needs to be on your home, the greater the cost. A large portion of these expenses will come from the installation process that gives your home a whole new world in the form of air conditioning.

What problems can your air conditioning face?

Unlike the common furnace, an air conditioner is a system of great complexity, something which is built on a number of mechanical conditions that must function in order for it to work correctly. Each mechanism is sized to meet a specific size in order to fit the “load” when the build commences. Both the amount of air flow across the internal coils and the amount of refrigerant are both huge factors in the system, and when either one of these fails to work properly, the whole system will begin to develop problems.

If, for a whole host of reason, the indoor heating in your home is at a high level due to the amount of people who occupy the space, the appliances that produce a lot of heat through the use of electricity or simply because of changes in the home, your air conditioning unit may start to falter as it struggles to keep up with the higher levels of demand from your home environment.

Given that the refrigerant charge of the system leaks, which it can, the capacity of the system could potentially begin to lower, depending on how much of this escapes in the process. Given this process happens, the cooling system will actually produce warmer air compared to the cold, so it won’t be able to keep up with the air when it gets hotter.

If the airflow amount across the outdoor coil is reduced, the ability to reject heat to the outdoor environment is reduced, again furthering the chance that the capacity of the system may be reduced, especially when the outdoor temperatures are high.

In dry climates, the same issues can occur when the indoor coil reduces as naturally, higher airflow will help the unit whilst lower airflow hurts the health of the air conditioning. In humid climates, the situation can become more complex as the hot air directly effects the performance of the unit. At higher airflows, there are less amounts of dehumidification, leading to high indoor humidities. If the airflow gets too low, however, the evaporator coil may freeze, which effectively breaks down the unit.

Keep Your HVAC in Good Shape this Summer

Your air conditioning system will be working overtime in the UK heatwave this summer – follow the BMS Aircon tips to ensure your heating, ventilation and air conditioning unit (HVAC) is working at its best:

1. Don’t let your HVAC work more than is necessary. And don’t let your office get too hot before turning it on. It’s key to regulate your temperature so as not to stress your unit. Keep doors and windows closed when your AC is turned on, and keep shades and curtains drawn on very hot days. Avoid having direct sunlight streaming in through doors and windows. As much as possible, don’t operate other heat-generating appliances in the daytime when your AC is going to be working.

2. Replace your air filters on a regular basis. Do this at least once every 3 months. Experts estimate that you can reduce your energy cost by as much as 10% by keeping up on this task. And the cleaner air will benefit your staff’s health as well. Air conditioning energy assessments are often undervalued!

3. Keep your thermostat constant. Changing your thermostat’s setting constantly can result in inefficiency. If you wish you can increase the temperature by a few degrees in the day time while you are away. When in cooling mode, switch on your AC fan to prevent hot or cold pockets from forming. This can also help prevent your condenser from icing up.

4. Keep your outside unit free of dust and dirt. Clear plants and other items from around its perimeter for at least 12-18 inches. Ensure also that indoor vents remain unobstructed to keep air circulation going for industrial air conditioning, this is so important.

5. Schedule regular tune-ups Have a reliable HVAC technician perform maintenance checks on your unit, preferably before the beginning of summer.
