Fixing Air Conditioning Problems

If the temperature is rising but the house isn’t cooling, there is a problem with your air conditioning system. When your air conditioning system is not working at all or not cooling the house enough, it’s important to deal with the issue immediately to avoid extreme heat in the house and additional damage to the equipment. 

Call for help with an air conditioner that: 

  • Suddenly stops working: When an air conditioning system suddenly stops working, the problem could be in the motor, thermostat, or a tripped circuit breaker. You can check the thermostat and make sure the breaker isn’t tripped before calling for repairs. 
  • Blows warm or hot air: You expect cool air when the air conditioner is turned on. If the air coming from the vents feels warm or hot, the refrigerant may be low, or a coil could be frozen. 
  • Makes loud, strange noises: If your air conditioner suddenly starts making loud screeching or rattling noises, it could be a faulty belt, compressor, fan, or motor. 
  • Leaks: A leak can be either refrigerant or water. When the condensate drain lines become clogged or the drip pan is cracked, it can cause a leak. 
  • Doesn’t evenly cool the house: When you have areas of the house that are significantly warmer or cooler than other areas, the system may be unbalanced. 

Identifying the root cause of air conditioning problems can be tricky, since one issue can have a number of different causes. A qualified HVAC technician has the training, tools, and expertise to evaluate your system, find the reason for the malfunction, and get it fixed quickly and efficiently.

Q: 01. How can I make my home feel less humid after a summer rainstorm?

Does your home feel too humid after a summer rainstorm? Here is a simple solution: run your air conditioning system a little longer than normal at a lower temperature than normal. Your air conditioning system is dehumidifying your home, while it is running. The system will draw all of the humidity out of your home and that cool feeling will return!

Zoning makes your home more comfortable and helps you save money on energy. Your home is divided into independent zones, as multiple thermostats are used. The climate is then independently controlled depending on your desired level of comfort in each zone. Most common examples of zoning are: separating the upstairs climate from the downstairs; establishing a special zones for sleeping and living areas.

By zoning, you have more control over different areas of your home, without having to regularly adjust the thermostat in order to reach desired level of comfort. Rooms inside your home, which are traditionally warmer than others, are easily cooled without placing extra strain on your HVAC system.

Regular maintenance is absolutely vital to the performance and lifespan of your heating/cooling system.

Benefits of regular maintenance are:

  • System will perform efficiently and you will be able to cut down on high energy costs
  • Prolong the life-span of the equipment; avoid unexpected and costly repairs
  • Maintain manufacturer’s warranty
  • Ensure system is running without risk to your health or/and safety
