Importance of Filter Replacements and Routine Maintenance

March 2018

Changing air filters is critical to the proper performance of your HVAC system, not to mention your home's air quality. Knowing what type of filter and when it needs replaced is essential to keep your system running efficiently, which is why we recommend routinely having maintenance performed on your HVAC system. Not only do your filters get checked/replaced, but other important checks and procedures are performed. Lack of changing out filters to the point where dust and debris is heavily coated on them can restrict air flow causing your unit to ice up or overheat; both of which can lead to additional damage to your unit if not addressed! If you have pets you might also find your filters need to be changed out more frequently, filters do their job by trapping all particles in the air before being fed back into your house. Providing you with cleaner air and helping prevent problems for those of us with allergies.

Preventative maintenance will encompass changing out your filters as well as checking your indoor and outdoor coil for additional dirt and debris coating them, checking your refrigerant charge, lubricating all moving parts, checking compressors, compressor mountings, overall health of the unit, and much more. If you are interested in scheduling a preventative maintenance or signing up with our team for a maintenance contract please contact us today!  


​​​Why Can't Oasis Air Continue to Recharge my Unit?

April 2018

“EPA regulations under Title VI of the Clean Air Act (CAA) are designed to protect the ozone layer. The region of the stratosphere containing the bulk of atmospheric ozone. The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere. Depletion of this layer by ozone depleting substances (ODS) will lead to higher UVB levels, which in turn will cause increased skin cancers and cataracts and potential damage to some marine organisms, plants, and plastics. The science page (http://www.epa.gov/ozone/science/index.html) offers much more detail on the science of ozone depletion and to provide for a smooth transition away from ozone-depleting substances (ODS).

On November 18, 2016, EPA issued a final rule updating its refrigerant management regulations. While the regulation took effect on January 1, 2017, some provisions had compliance dates of January 1, 2018, and January 1, 2019. Amongst other things, that rule extended the refrigerant management requirements to common substitutes like hydrofluorocarbons (HFCs).”

In general, owners or operators of an appliance that is leaking refrigerant above the applicable trigger rate must either:

  • Repair leaks within 30 days from the date the leak was discovered, or
  • Develop, within 30 days, a plan to retrofit or retire the appliance and complete the actions under that plan within 1 year.

Commercial refrigeration Leak Rate

2018- 35%

Starting January 2019- 20%

Comfort cooling (residential) Leak Rate

2018- 15%

Starting January 2019- 10%

"My AC isn't working, what do I do?"

May 2018

Sometimes when your A/C won’t turn on it can be resolved without needing to schedule a service call. Most often the reason behind your unit not working is due to power. Check your circuit breaker to ensure it hasn’t tripped, check power to your unit, as well as power to your thermostat. Some thermostats require batteries be changed, others are wired (in the event your thermostat is wired and not showing a display, but has power feeding to it, we would recommend a technician trouble shoot the problem). After finding all power sources operational, check your thermostat settings. Your thermostat should be turned to cool and set a few degrees below the actual room temperature. All doors and windows should be closed to ensure optimal cooling in your home or office, your unit will struggle to meet the requested temperature if they are open, causing it to run continuously. If your thermostat is set too low this could cause problems with your unit icing up, so be sure you don’t continue to lower the temperature at your thermostat hoping the unit will cool faster or better. On hotter days if you call for your unit to cool, it could take a longer period of time to meet the temperature requested, giving the unit ample amount of time to cool your space is recommended before calling in. If you find these troubleshooting tasks do not solve your cooling issue, please call in to your trusted HVAC contractor!

​Problems that indicate a technician is needed:

​Unit blowing air but it isn't cold

​Water leak from indoor unit

​Lines at unit are frozen

​Unit is running but no air is coming through the vents


Energy Saving Tips

June 2018 

To get optimum heat and cool from your unit without excessive energy use we recommend performing routine maintenance regularly. Most residential homes (depending on usage of system) require yearly maintenance. If your unit is running day and night and rarely off, we can recommend every six months to ensure filters are clean and the unit is running efficiently. Checking your air filters regularly is highly recommended, whether done by an HVAC professional or yourself. If your air filter is dirty it can restrict air flow and make your system work harder which in turn uses more energy, thus costing more. At Oasis Air we stock and provide EZ Flex filters which are MERV 10, meaning they are a higher efficiency filter that traps more dust, dirt, and debris. They are also larger in size so their life expectancy is longer than that of a 1” filter. Smaller filters require at least every 3 months to be changed out. Energy Star recommends “A programmable thermostat which is ideal for people who are away from home during set periods of time throughout the week. Through proper use of pre-programmed settings, a programmable thermostat can save you about $180 every year in energy costs.” Lastly, ensuring that you are getting optimum air flow not only pertains to your filter but also your duct work. Patches or holes in your duct work cause air to dump into your attic (or where ever your duct work runs) and not into your home, ultimately causing your unit to run continuously to meet set temperatures when air flow is redirecting elsewhere. Following these few tips can help you save money and energy in the long run!


R-410A Replacement Refrigerant


February 2019

Carrier has chosen Chemours Co. to replace R-410A, announcing that R-454B will be the next generation refrigerant. “Opteon XL41 has been selected by Carrier Corp., after extensive testing and evaluation, as the primary lower Global Warming Potential (GWP) refrigerant to replace R-410A in ducted residential and light commercial packaged products sold by Carrier in North America.” EPA standards are ever changing to move toward environmentally friendly, and sustainable solutions. “Carrier Corp. choosing R-454B enables them to achieve their exacting performance standards, while exceeding the anticipated requirements of future regulations.” R-454B will reduce CO2 emissions by 78% over R-410A, it will improve energy efficiency, and lower the GWP percent by 30. This new refrigerant will achieve the maximum GWP all while satisfying long term requirements. 

As we gather more information on this change, we will keep our customers informed. It is still early in the development of the refrigerant, and news pertaining to it. R-454B isn’t planned to be introduced until 2023.
