Yes! Your heating and cooling equipment is a major financial investment; routine maintenance protects that investment.

The best time to have us come out and service your heating and cooling equipment is at least twice a year – before summer and before winter – to ensure your HVAC equipment runs as efficiently (lowest energy cost) and effectively (highest comfort level) as possible. Not only will the pre-season visits extend the life of your equipment, our expert technicians can spot and correct any potentially serious problems before they turn into a costly repair. In addition, you’ll rest easy knowing that your HVAC system will not cause unexpected issues when you need it most during peak seasons.

It is very important! A dirty filter will slow down airflow and make the system work harder to keep you warm or cool – wasting energy. A clean filter will also prevent dust and dirt from building up in the system preventing expensive maintenance and/or early HVAC system failure.

ENERGY STAR™ recommends that you check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. The frequency of replacement depends on the season, climate and number of occupants. A standard filter should be replaced every 2-3 months.

The quality of your indoor air is very important to you, your family and anyone in your household including your pets. The chemicals, particles and other contaminants that you might encounter during the course of the day are often harmful to those in your home. Evaluating and optimizing the indoor air quality of your space is a vital step in ensuring that air quality is constantly high for you, your family, your employees and patrons. AirOstat believes that every client deserves to enjoy comfort indoors devoid of allergens, pollutants, irritants or anything else that might cause discomfort or unwanted health effects.

A ductless mini-split is a system that can be installed so that it could serve a single room, garage, office space or multiple rooms and works without the need for ducts. This can save you money on HVAC installation costs over traditional air conditioning installations because your home or office space will not require any special ductwork if you are looking to only heat or cool a specific area of your home or business.

More than likely, it is either low on refrigerant, low on airflow or there is a leak. Replace your filter and allow the unit to thaw out. If the problem reoccurs, call AirOstat, Inc. to schedule service on your cooling system. We recommend having annual maintenance performed to keep your HVAC systems in peak operating conditions.

To improve the overall performance of your overall system, call AirOstat, Inc. for a consultation if: 

Your heat pump or air conditioner is more than 10 years old.
We encourage all Los Angeles homeowners and business owners to consider replacing your current unit with a unit that has earned the ENERGY STAR™ label. Installed correctly, these high-efficiency units can save up to 20 percent on heating and cooling costs.

Your furnace or boiler is more than 15 years old. 
Consider replacing with an ENERGY STAR™ qualified furnace, which is 15% more efficient than a conventional furnace. If you have a boiler, consider replacing with an ENERGY STAR™ qualified boiler that is 5% more efficient than a new, standard model.

Your equipment needs frequent repairs.
If you are constantly calling for repairs, it may be time to consider replacing your furnace and/or AC unit. The investment will save you money in the long run and end the revolving door of service repairmen in your home or business space.

Central air conditioners and heat pumps resemble each other in appearance, using the same casing. Both units reside on the exterior side of the property.

A central air conditioning unit is solely responsible for cooling, while an interior furnace takes care of heating portion.

A heat pump is really two units in one – an air conditioner, and in the winter months, a heater. When the heat pump is in the heating mode, it pulls heat out of the outdoor air and uses that to heat your space. If the outdoor air is too cold (around 32° F), then it uses electrical strip heaters to heat the air. Because a heat pump is utilized year-round, the unit will require more routine maintenance checks and shorter replacement times than standard air conditioner units.

SEER stands for “Seasonal Energy Efficiency Ratio”. The higher the SEER rating, the more efficient the system. By federal law, all units must be a 14 SEER or higher. 

AFUE stands for “Annual Fuel Utilization Efficiency”. This rating tells you how much of your heating dollars are converted to heat energy put into your space and how much is lost up the flue pipe. Federal law mandates that all furnaces being produced today be at least 80% efficient. Air-O-Stat, Inc. offers many furnace options up to 98% efficiency.

Yes! AirOstat, Inc. has partnered with different financing companies to offer a variety of plans that allow homeowners to take care of home comfort today and pay for it later: including our no-interest option with regular payments. The initial verification is a ‘soft pull’ and does not affect your credit.

For families that are always on the go, programmable thermostats are a must. Programmable thermostats allow you to set your system at different temperatures throughout the day. This means reduced energy use throughout the day! Installing a programmable thermostat is a great way to start saving energy and money while your family is away or sleeping.

Heat rises, thus the reason it’s hotter in the summer. Assuming the system was sized and installed correctly, you should consider installing a zone system if possible.

Zoned thermostat systems allow you to control the amount of heating and cooling by zone, meaning greater control of your comfort. Sometimes the addition of return air ductwork will help improve air movement and help make upper levels more comfortable.

UV is the abbreviation for ultraviolet. Located in the return air ductwork and by the indoor cooling coil, the ultraviolet air treatment system continuously emits high – intensity ultraviolet (UV) energy. The energy eliminates (kills) a very high percentage of airborne bacteria and germs passing over the UV light field inside the ductwork. The UV light mounted next to the indoor cooling coil will help eliminate the growth of mold, mildew and other contaminates from the coil surface.
