Frequently Asked Questions

Our most frequent heating & cooling questions and answers

What regular maintenance is required to keep my HVAC System running properly?

Always ensure that there are no restricted air flows within your HVAC system. Three common culprits of air flow restriction are dirt, dust, and debris. It’s crucial for both outdoor and indoor units that all filters are cleaned regularly. In addition, the coils and heat exchanges must remain clean and clear of any blockages or restrictions. It’s strongly suggested to have your system serviced by a professional twice yearly.

How Often Should My Air Conditioning System Be Serviced?

Maintenance of your air conditioning system should be done at least twice a year. During the beginning of spring and about 6 months later. This will ensure that your heating and air conditioning system is prepared to operate efficiently during the summer months. Proper care of your HVAC system will also allow you time to tend to any potential issues with your heat and cooling unit.

Why is it important to replace the filters regularly?

Changing your air filters regularly is the number one way you can maintain your HVAC system. The air filter is responsible for filtering out dust, pollen, and other particles to maintain high air quality inside the home. Also, when your filter is clogged the blower motor has to work harder to draw the air from your home. A system that’s straining to cool the house means higher energy costs for the homeowner and more wear and tear on the system. This will eventually lead to thousands of dollars in preventable repairs or an early system replacement.

How often should I replace my air conditioner filters?

If your system utilizes disposable filters, it’s best to replace them each month. Washable filters also require cleaning each month. These monthly maintenance checks will ensure that your system operates at maximum efficiency. We recommend our service plan where our techs inspect and clean your system twice a year. Part of this service includes servicing the filters. These routine maintenance checks will keep your HVAC system operating smoothly year-round.
