Modern HVAC Solutions
The HVAC industry continues to grow and innovate using the latest technologies. The industry is incorporating smart technology and integrating with Google, Amazon, and others. Remote monitoring of residential heating and air conditioning systems is becoming more widespread. Inverter technology has made it possible to achieve extremely high efficiencies. Zoned ventilation systems use wireless technology to let homeowners customize comfort room to room and individual to individual. As the technology advances, technicians must be open to continued learning.
Smart Home Integration
Virtually every major HVAC thermostat manufacturer now makes a thermostat that integrates with most smart home systems. This allows the homeowner to use voice commands to adjust thermostat settings. They can also monitor and adjust their home heating and air system using smart phone applications. They have learning features that adjust your the homeowners personal preferences. Another feature is geofencing that will start your HVAC system based on your location. These are some of the more popular brands being sold by HVAC companies today:
Systems have been and continue to be developed that allow your heating and air company to remotely monitor your residential HVAC system for inefficiency, problems, run time, and failure. Communicating HVAC systems now have some remote monitoring capability. Remote monitoring systems such as Sentree allow you to remotely monitor refrigerant temperatures, pressures, and compressor current. You get live temperature data for ambient air, vapor, and liquid lines, calculated superheat and subcool, up to the minute PSI measurements for liquid and vapor line pressure, and real-time amperage readings. You can also monitor air conditioner condensate drains, home humidity, and indoor temperature. Historical data and analytics companies to provide proactive HVAC repair and maintenance which can lead to more efficient service dispatch and increased satisfaction for homeowners.
Inverter technology isn't new to the HVAC industry. Inverter driven HVAC equipment converts AC power to DC and back to AC. This greatly reduces starting and operating currents which reduces power usage. Manufacturers are continuing to use it in new ways to make an air conditioner more energy efficient. It is becoming increasingly affordable. 20 SEER systems are now available in ducted and ductless systems. Inverter systems are very good at reducing humidity because they run for longer at lesser power. Controlling humidity is vital to indoor air quality reduction. Inverter technology is being used in the following HVAC equipment:
- ductless heat pump
- heat pumps
- Straight cool air conditioner
An HVAC solution that was once reserved for commercial HVAC applications has became popular in the residential HVAC industry. Zone control gives homeowners increased control of their HVAC system. Every homeowner has experienced the "hot room." Many homes have portions of their homes that don't heat or cool as well as the rest. Zoned HVAC systems allow room to room control over temperature with having multiple air conditioning systems. Zoning is accomplished by separating the air supply to each unique area using a ventilation damper in the duct work. The damper is then controlled by an individual thermostat. HVAC companies can also use occupancy sensors to control the operation of these dampers. A zoning systems can be combined with two stage or variable speed HVAC equipment and indoor air quality products. Zoning can be conveniently done in parallel with any air conditioning installation.
Question: What is SEER?
Seasonal Energy Efficiency Rating (SEER) is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. A typical analogy for this is miles per gallon. Air conditioners and heat pumps are currently being manufactured at minimum energy efficiency of 14 SEER.
