Digital Thermostat controlled via Wifi

Ecobee and Nest thermostats have revolutionized how we use air conditioning systems in a smart way. Today, not only can you turn your air conditioner off and on, the Nest Thermostat for instance, learns yours and your family’s habits so that it automatically adjusts to help you save power by means of a motion sensor. It also enables you to see the temperature inside and outside your house and you can even change the thermostat temperature online or by using own mobile app.

You will receive a monthly email informing you of your air conditioning system’s power consumption.  It also calculates Kw consumption by multiplying it by the price per Kw in order to generate statistics on your saving per month. You will keep the historical data.

These thermostats are compatible with most brands in cold only, cold and hot and heat pumps. They can also be compatible with some commercial systems and are easy to install and configure.


How do you choose your air conditioning contractor?

Do you want to know how to find an air conditioning contractor you can trust and let into your home?


Does the contractor have a HVAC/R License?

Let me tell you how to find it out. HVAC businesses specializing in air conditioning, heating, air quality and refrigeration need a license issued by the State of Texas in order to operate. This is obtained after going through the certification process that serves to validate knowledge on the responsible handling of the different refrigerant gases used for the different residential and commercial air conditioning systems and also for refrigeration systems. The licenses are classified according to tonnage: one of them is for working on systems no larger than 25 tons and the other has no tonnage limit. Furthermore, holders of these licenses must be insured against liability for at least 1 million dollars so they can be answerable to any damage caused to your property. The agency responsible for the rigorous control of this area is the Texas Department of Licensing and Regulation. You can find licensed technicians using this government search engine and can filter by city or zip code to identify those who are geographically closer to you. You can see this option when you click on the link.

Rio Air’s license TACLB017479E is directly endorsed by the owner of the business, Antonio “Tony” Lerma.

Equipment is very important

Air conditioning and refrigeration systems require precision instruments and tools that can carry out superheat or subcooling (procedures to adjust the correct operation of your air conditioning). To carry these out we need electronic instruments that measure the ambient temperature and injection temperature of your air conditioning system. Based on the temperature and type of cooler you have, we load your refrigerant system so you do not have to worry about it at any time of the year. You system will be configured at all times in accordance with your equipment supplier´s specifications. Does your air conditioning supplier carry out these procedures?

What brand of air conditioning system should you choose?

Answer these questions before buying an air conditioning system:

  1. How many tons of air does your house need?
  2. Do you want air conditioning and electric heating?
  3. ¿Do you prefer air-conditioning with heat pump?
  4. What efficiency of SEER will you buy?
  5. Should it be necessarily a R-410a coolant?
  6. Do you want a two-stage variable speed compressor?
  7. Would you like it to have the standard one speed indoors and outdoors?

Nowadays there is a wide assortment of HVAC brands and variants. That could confuse you when you choose what to buy.

The first thing you should know about it is that your HVAC provider has a preferred brand that wants to sell you. And, if you want something else, they will raise the price to persuade you to buy the one they offer.

The warranty of the appliances is very important. That is why you shouldn’t forget to register them online directly on its brands website. That is the only way you can be sure that they will respect the warranty. The due date of the warranty for the compressor can range from 10 years to life, and the internal machine can have a minimum of five up to 10 years of coverage. Most of them offer a year of service.

Once you have chosen a brand, tonnage, type of heating, and SEER efficiency, keep the documentation of the purchase and the contract you signed with the air conditioner provider. We would be pleased to be your supplier at Rio Air soon.

Benefits of maintaining your air conditioning

The benefits of maintaining your air conditioner

Enjoy the comfort of an air conditioning system without spending too much.

Heating, air conditioning and ventilation systems consume most of the energy you use on a daily basis. Furthermore, if the evaporator is dirty, the blower will be working for longer and will have to consume more power, which will be reflected in your electricity bill. And if that weren’t enough, the pressure on the refrigerant could rise and subject the compressor and other system components to unnecessary wear and tear. Follow these recommendations so that this does not happen and you do not consume too much:

Clean the evaporators. Yes, both of them.

The machine that is usually installed in the attic or the closet has an evaporator, which should be free from any impurity that could obstruct the passage of air. Otherwise, when it comes to transfer the heat transported by air from your house to the cooler, it won’t be able to this efficiently, which will keep the condenser blower operating for longer. The condenser should be cleaned so that the system works properly.

Change the air filter.

We recommend changing the air filter once a month, since if the system’s evaporators and filter are dirty, this is sure to increase pressure and power consumption, and corrective maintenance will be required.

Let Rio Air do the job. By signing an annual maintenance policy, you will enjoy the benefit of keeping your air conditioning system operating correctly. Contact us and ask about our prices.
