  • What safety precautions need to be taken when repairing an air conditioner?

    Repairing an air conditioning system is highly complex, which is why any work must always be conducted by a professional and certified HVAC technician, as they are experienced and knowledgeable in how these pieces of equipment function. When hiring a professional HVAC company, you can rest assured knowing that the technicians working on your cooling equipment are following stringent safety protocols at all times. Here is a closer look at some of the safety precautions that will take place in more detail below:

    1. Turn off the power: Your technician will always turn off the power to the air conditioner before performing any repairs. This can help prevent electrical shocks or fires.
    2. Wear protective gear: Your technician will wear protective gear such as gloves, safety glasses, and a dust mask to protect themselves from debris and chemicals such as refrigerants which are used in air conditioners that can be hazardous. 
    3. Keep the area around the air conditioner clean: Debris and clutter can make working on the air conditioner challenging and create hazards. Therefore, your technician will keep the site clean and organized to make repairs more manageable and safer.

    Once the repair has been completed, your technician will then conduct a series of system tests to ensure your air conditioning system functions correctly while meeting any regulations and requirements. Remember, it is always best to ensure that you have any and all air conditioning system repairs conducted by a professional HVAC technician to avoid potential injuries and mistakes.

  • Why does my air conditioner run but not cool?

    If your home’s air conditioning system is operating but not cooling the inside of your home, there are actually numerous reasons why this may be happening. Therefore, the team at Dunn Heating has put together a list of explanations that may relate to your current issue. Here is a closer look at why your air conditioning system may be running but not cooling your home in Kitchener-Waterloo:

    1. Low refrigerant: If the refrigerant level in your air conditioner is low, it may not be able to cool the air effectively, which could be because of a leak in one of your cooling compartments. 
    2. Dirty air filter: A dirty air filter can restrict airflow through your air conditioning unit, reducing its ability to cool. Luckily, replacing the air filter can help improve the performance of your air conditioner.
    3. Faulty compressor: The compressor is a vital component of the air conditioning system. If it is not functioning correctly, the system will not be able to cool the air effectively.
    4. Malfunctioning thermostat: If the thermostat is not calibrated correctly or is not functioning properly, it may not be able to accurately control the temperature in your home and will need to be reset. 
    5. Obstructed airflow: If the airflow through the system is blocked, it can reduce the system’s ability to cool. This could be due to debris, blockages in the ducts, vents, or problems with the outdoor compartment.

    As you can see, there are several reasons why your current air conditioning system is operating but not cooling your home. Therefore, if this is something you are currently dealing with, we recommend reaching out to the team at Dunn Heating to book a repair appointment as soon as possible. Remember, catching problems and having them professionally repaired promptly is the key to ensuring you do not face costly repairs later down the line.

    What safety precautions need to be taken when repairing an air conditioner?

  • Is air conditioning repair worthwhile?

    Whether repairing your air conditioner system is worth it will depend on several factors, including the age and condition of the system, the extent of the repair needed, and the cost of the repair.

    If your air conditioner is fairly new and the repair is minor, it may be worth having the system repaired. However, if the system is older and always needs regular repairs, it may be more cost-effective to replace the system rather than continuing to pay for repairs. It is also essential to consider the cost of the repair in relation to the price of a new system. If the repair cost is significantly less than the cost of a new system, it may be worth it to have the system repaired. However, if the restoration cost is close to or higher than the price of a new system, it may be more cost-effective to replace the system.

    Ultimately, deciding to repair or replace your air conditioner system will depend on your circumstances and personal needs as a homeowner. However, we always encourage homeowners to reach out to an HVAC company in their area to get a professional opinion before determining their next steps. Therefore, if you are unsure whether you should have your air conditioning system repaired or whether it is time to purchase a new unit, we suggest reaching out to the team at Dunn Heating to book a consultation appointment with one of our technicians!

    Dunn Heating is available around the clock, 365 days a year.

    1. Your air conditioner unit is not turning on or is having difficulty starting: If your cooling system is not turning on or is having trouble starting, there may be a problem with the electrical components or the thermostat.
    2. You are having difficulties cooling your home: If the air from your vents is not as cool as it should be, or if the system cannot maintain a consistent temperature, there may be a problem with the system’s refrigerant levels or with the compressor.
    3. Strange noises are coming from your air conditioning system: If your air conditioning system makes unusual noises, such as grinding, squealing, or clicking, this may indicate a problem with the system’s components or the air ducts.
    4. Your air conditioning equipment is leaking water: If your air conditioning system is leaking refrigerant or water, this may indicate a problem with the system’s seals or the evaporator coil.
    5. The air conditioning system is blowing warm air: If your home’s air conditioning unit is blowing warm air instead of cool air, this may indicate a problem with the system’s refrigerant levels or the compressor.
    6. Your cooling equipment is cycling on and off frequently: If your cooling system turns on and off often, this may indicate a problem with the thermostat or the system’s capacity to cool your home.
