Denair HVAC

1. Why my system consumes more and more refrigerant each year?

An air-conditioner system that needs recharge of refrigerant on a regular basis is leaking and requires fix. Leaking refrigerant causes your unit to lose cooling capacity and also use additional energy; it’s also hazardous for the environment. Refrigerant and gases released into environment are among the worst culprits in depleting the ozone coating. Denair possesses the latest modern technology to discover and fix refrigerant leaks, since the old methods are costly and time consuming.

2. Why some areas in the premise are too hot and others are too cool?

There is a variety of possible causes for climate changes in the area. Probably the most common is lack of sufficient air flow to your system. This can happen when you have holes and crack in ducts, closed off or blocked vent, or clogged filters. It’s also possible that some elements of your system may be outdated, and easy modifications may improve the air flow. Another reason might be if space layout has changed without updating air conditioning equipment as well as duct layout, it may be time for a system re-design. Another typical cause of temperature variance is insufficient maintenance.

3. Can’t I get my servicing personnel perform the cleaning?

In some cases you can, especially if the equipment is under heavy load. However, we recommend at least twice a year to have professional technician clean and maintain your system. We use special professional cleansers. Moreover, some of you system components are dangerous for untrained stuff, such as fan blades, for example. Certified HVAC technician will also check electrical connections, refrigerant charge, inspect the entire system for worn components and any signs of upcoming stress.

4. Why do I need to change the filters?

Regular filter change will help your heating and cooling system operate at peak level and improve indoor air quality. It is important to replace filters regularly to guarantee appropriate air-flow and to maintain your home free from dust, allergens and germs. Based on the type of filter you have, you might require every week or monthly filter change. Denair can carry out inspection and suggest the most suitable filters and schedule of replacement.

5. Is it important to choose the right size of HVAC system?

Two main reasons why the size of HVAC system matters are comfort and energy use. Over-capacity equipment will not be as energy efficient as appropriately matched capacity. In turn, under-sized system will definitely lead to loss of comfort and temperature extremes.

6. What size HVAC system do I need?

The basic rule is that 1 ton of air conditioning can cool from 300 to 800 square feet, but it also depends on the construction and layout of the premise. Therefore, the only right way to estimate the size needed is to have licensed technician, who will evaluate individual heating and cooling needs.

7. How do I know that my A/C unit is big enough?

The main features of the AC system that you should take into account are performance and efficiency. Before making a decision, you may want to invite professional who will determine the proper size and make recommendation on equipment required.

8. How important is to have quite heating and cooling system?

It is extremely important as continuing exposure to sound levels of 90-95 decibels may result on hearing loss.
