A system that is too large will cool or heat your house quickly, but you may not feel comfortable. That's because it will satisfy the thermostat before it can adequately remove sufficient moisture from the air during the cooling mode, leaving you feeling sticky and humid. This could even lead to moisture and mold problems. And, the stress of short-cycling (too many starts and stops) will shorten the life of your equipment and increase your heating and cooling bills.

On the other hand, a system that is too small just cannot get the job done, especially in extreme weather conditions. The air conditioner will run constantly in the Summer and the furnace will do the same in the Winter.

But a correctly sized system isn't just based on the size of the structure. Many factors go into determining the size of the system. Including type of house and walls, type and size of windows, insulation, basement and attic conditions, house orientation, and so on. A Technician must visit the house and take detailed measurements and notes while conducting the survey.

R290 refrigerant gas, also called Propane, is a highly pure liquefied petroleum propane gas globally used as an environmentally friendly refrigerant gas. According to the Environmental Protection Agency – EPA, R290 is quite safe for the environment as it has the least ozone depletion and the lowest Global warming potential at 3.3 times carbon dioxide.

EPA also recommends this R290 refrigerant be used in any food & beverage, hotel, restaurant, and others.

It is very famous and common as a replacement for typical refrigerants and air condition units such as R-22. This highly flammable R290 refrigerant is a very attractive solution for any medium-temperature commercial refrigeration unit, freezer unit, air conditioner unit, heat pump, display case, domestic freezer, and other HVACR applications.

There are an abundance of possibilities that can cause your HVAC system to freeze up; almost all of them usually need to be corrected by a professional technician. Determining the air filter is clean or replaced and making sure the airflow is not restricted are about the only tasks a homeowner should safely identify or handle themself.

Low refrigerant: In some cases, freezing up is initiated by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, leaking valves or loose fittings can cause leaks. The length of time your system has been installed and the nature and location of the leak are the determining factors on whether to have the system repaired or replaced.

Dirty evaporator coil: Over time, the evaporator coil will become dirty. On these occasions, the results are similar to those of having a dirty filter. Gradually you will lose airflow, slowly enough that you probably would not realize it until it freezes up or is not cooling adequately. You will need to contact Troubleshooter 007 to solve the problem to remedy the problem.

Defective blower motor or relay: A blower motor running at an improper speed or not running at all can cause freezing. It can also be sporadic, starting at full speed and slowing down after it heats up. Or a relay could cause it to start one time and not the next. In either case, you will need to contact Troubleshooter 007 to solve the problem. to correct the problem.

Should you discover that your system was freezing due to a dirty air filter, after replacing or cleaning the filter, you can hasten the thawing process by turning the system off and then turning on only the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, switch the system settings back to normal. If the system refreezes, contact Troubleshooter 007 to solve the problem.
