MRCOOL SmartHVAC App works with MRCOOL Smart Controllers to convert MRCOOL Air Conditioners & Heat Pumps to smart ones. Our smart controllers work with this App to help you convert your existing or new ACs to smart ACs. You can control your MRCOOL ACs through your smartphone or simple voice commands (our smart controllers are Alexa & Google Home enabled). These DIY controllers are extremely easy to setup. You can automatically turn the air conditioner or heat pump OFF when you leave the premises and start to cool/heat once you arrive as per your settings. This App gives you complete control of your heating and cooling. It figures out when you're at home and when you're out and adjusts the settings to provide comfort and energy savings. You can set weekly schedules for your air conditioners, monitor usage history, set air conditioning action in relation to your locations, see the air filter status of your AC and lot more. You can set intelligent temperature based triggers for your air conditioners by using the ‘Comfy’ feature under ‘My Rules’ section of the app. Comfy lets you set triggers to personalize the operation of your AC. It helps you automatically change your AC settings if room temperature goes above or falls below a pre-set value. It helps you reduce your energy bills with lot of convenience. Continued use of GPS running in the background can dramatically decrease battery life.

MRCOOL SmartHVAC's advantage is ratings volume (9.8K vs 1) and iOS requirement (13 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
