Hiring a licensed HVAC company is a good idea when you are looking for one. It is important to hire an HVAC contractor who is licensed for several reasons. You should make sure they have the correct equipment. They can also provide repair and warranty services. It is important that equipment installed by these companies can withstand temperatures at certain levels. Warranty service should also be provided if necessary. Reputable companies do not require you to pay upfront for services.
If you don’t feel confident enough cleaning the evaporator tubes yourself, you could refer to the owner’s manual for instructions or look at online tutorial videos. However, these instructions should only be followed if the homeowner is a competent DIYer. It is best to hire an HVAC maintenance professional if you don’t have the skills. After cleaning the unit, make sure you turn it off before moving on.
No matter if you're servicing a central or window air conditioning unit, it is important to turn off the cooling system first before you can remove the filter. Rubber gloves are recommended to remove the filter. Make sure you use a bristled attachment for your vacuum cleaner when cleaning the filter. For extra dust removal, you should vacuum filters located behind return vents.
If you are installing a thermostat for central heating and cooling systems in your home, be sure to set it at the desired temperature. It is possible to program your thermostat several hours before you leave work if you prefer your home to be warm in the morning and cool during the day. But, before you do anything, consider how everyone lives and what their daily routines are. It is better not to set your thermostat at 70 degrees Fahrenheit.
The cost of maintaining an AC system can be increased by calling an HVAC technician for an emergency call. This could add $100-200 to your overall maintenance costs. Most emergency calls are made after normal business hours, on weekends and holidays, as well as during busy times. An emergency call is usually the best option. However, a refrigerant or motor problem can wait until business hours. High temperatures are another reason for emergency maintenance calls. You can turn off your system if you experience high temperatures until a technician arrives.
Turn off the air conditioner and remove the access panel. After the access panel is removed, you can see the evaporator coil. Use a no rinse cleaner to remove any stuck particles. To remove more stubborn particles, you can use a paintbrush and a gentle nylon brush. You can repeat this process until you are happy with the cleanliness and appearance of the evaporator coil.
Once you narrowed down your search, contact the companies and request a quotation. Look for a detailed estimate along with the technician’s experience and credentials. It's important that you verify that the technician is authorized to work in the home. A technician with a license is someone who has been properly trained and experienced to do the job. You don't want anyone who doesn't have certifications working with your central air conditioning system.
