What Should You Try When Your Heating or Cooling System Doesn’t Turn Off?

When the AC or heating unit doesn’t turn off, it’s usually a problem with the thermostat. As it gets older, for example, an AC/furnace unit still relies on relay switches to maintain the communication between the thermostat and the fan. As time goes by, these switches may become damaged or even unusable, in which case they will prevent that communication entirely. If that happens while the fan is on, then it’s possible for it to stay on, as it no longer receives the command to stop when you turn it off.

There are other considerations as well. In case only your AC unit doesn’t turn off, there may be an issue with its condenser coils. Since the AC system relies on the use of a condenser to remove heat from the air, it’s possible that hot air is no longer removed from the air, so the AC becomes stuck in an endless loop  trying to keep seeping away heat until it gets confirmation from the thermostat that the target temperature has been reached.

It’s also important to check the fan limit switch, as it could be a problem with that as well. Other than that, just keep in mind to call your HVAC furnace service Denver professionals and ask them to help you out, if you can’t find any problem, as the malfunction might be related to something a lot more serious

Choosing the right filters for your HVAC is extremely important especially in the light of the current pandemic, as you might face issues such as people believing that your HVAC is spreading the virus. While such claims are unsubstantiated, and there is no evidence suggesting that HVAC systems can actually do that, it’s always best to take precautions and install a superior quality filter. Instead of looking for specific brands for your filters, consider what your best guidelines might be for choosing a top quality filter without needing to ask anyone about it. Some people believe that a higher MERV rating is the best choice to go with. However, as in demand heating repair Denver specialists will tell you, that’s not the case necessarily. A higher MERV rating also means that your filter will present a lot of air resistance and your HVAC will have to work overtime to keep up with it. For best results, aim to select the right size and type of filter. The size should become obvious w...

Are A/C Warranties a Good Deal?

Image
For air conditioners there are two types of warranties: factory warranty covering the equipment and spare parts installation warranty from the installer, which refers to repairs related to installation, refrigerant route or electrical connections For your protection, air conditioning repair Denver technicians suggest that you insist on receiving a written warranty for both equipment and installation. Warranties are important because they cover all defects of mechanical or electrical nature, under the conditions described in the warranty certificates issued by the manufacturer. The warranty refers only to the air conditioner for which it was purchased, and which can be identified based on its serial number, the manufacturer’s warranty certificate and the purchase invoice.

An air conditioner covered by a warranty benefits from an intervention period. If the...

Will Air Conditioning Help Allergies?

Image
Although they can filter particles such as pollen, air conditioners may also become a suitable environment for the development and multiplication of organisms (viruses, bacteria), which can spread rapidly especially indoors. Also, this type of appliance emits aerosols – small particles of organic or inorganic origin – which have a strong allergenic effect. Because the air does not have the necessary humidity, it decreases the immune resistance of the airway mucosa and thus, we can get serious allergies and more. Air conditioners also reduce the body’s ability to defend itself and thus increase the risk of infections, the airways being among the first to be affected. Allergies and respiratory infections can be avoided if: The air conditioner is set to the temperature of 24-25 degrees C instead of 21- 22, as it is usually used. Do not install air conditioning in the bedrooms, but rather in the hallway, in order to cool the rooms indirectly. At work, make sure that desks are located ...
