Are smart thermostats worth it?

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

Do I need more than one smart thermostat?

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Will I save money with smart thermostats?

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.

"No findings, no solution, no explanation… collected the fee… the issue is still there. I had Triad Mechanical Company for our HVAC issue that the outdoor unit is not running. I told Paul, the assigned technician, that we had tried resetting the power to the outdoor unit but that only brought the unit back on running for a few days before it stopped running again. I asked Paul’s help diagnose the issue for the root cause. However, when I came to the property just a few minutes later than Paul, he told me that he had done his work already, well, by simply resetting the power to the unit! (although I told him that we already tried that but it didn’t work!)… He didn’t have the patience to explain to me what diagnosis he had done (within that a few minutes) and he didn’t even bother to come off his truck to show me but saying “go ask your tenant”. He collected the fee and left. I will never trust nor use Triad Mechanical Company again!"

"I am/was/and always willing to let people/company's make things right but they have not. Unless you want to be hustled, left without hot water, poorly advised and live with total buyers remorse DO NOT CALL F+...see below for details I am still at a loss for words...and am reminded every time we use water in our house that we were taken advantage of.. Everything started out fine but then turned into a rollercoaster ride that ended with our family left stuck with a larger bill and our home plumbing worse than we started..here is how it played out: 1. November 2019 the hot water tank that came with our house died (keep in mind this tank was going for at least 15 years in our dirt crawl space with NO PROBLEMS) and the thermocouple finally gave out from what seems it getting wet..remember 15 years of rain 2. After researching several companies/deals I settled on Cool Air and talking to them before, during'ish, and after was fine. 3. When the plumber came to evaluate the area to ensure what I ordered would work, I specifically asked him if the tank sitting on the dirt would be a problem and if we could raise it off the ground? 4. I was ensured that A) "these new tanks are made to withstand water.." B) due to the ceiling height and requirements to have the flume/gas line a certain way it was not possible and we needed a min 50-gallon tank to be up to code C) eventually the plumber "caved in" and put a dish/pan underneath the tank but said it was completely unnecessary but in the end price was good... the job was done in a quick/efficient manner and no mess left behind ** At this point A+ rating .... 5. Fast fwd 2.5 months..all is good the tank is amazing..I am out of town in DC and my wife calls and says the hot water is out..mind you, we have 3 children under 12 yrs old 6. I call CoolAir from DC and ask if someone can look at the tank as my wife was not able to get the pilot light lit 7. CoolAir kindly sends one of their plumbers out late night to light the tank and review the situation..A+ still 8. The plumber calls me from the crawl space and asks me why I had the tank put on the ground as it SHOULD NEVER BE PUT ON THE DIRT...and that the tank is ruined and can't be fixed and needs to be replaced..needless to say, I was confused..upset..and now my wife and kids in mid-Feb (no snow but cold) are now 4 days without hot water 9. CoolAir's head of sales personally goes onsite the next day and apologizes and agrees with the plumber's assessment and said the tank should have never been installed and directly told me the only option is to go tankless...$2k more than what i paid 10. I asked again ..can I raise the tank..same answer..NO..I must go tankless...but was assured... I will have near-instant hot water and if we are going to remodel this will cover the whole house no problem 11. After 5 days of my family with no hot water and Cool Air being kind enough to offset the cost of the Tankless with what I already paid...(A/A- grade now)..I cave in and give the go-ahead 12. The crew arrives to install the tankless on a Friday..I confirm their arrival and land back to ATL Friday around 4 PM and as I am in the Uber they said they were done and leaving...so I ask my mother-in-law to tip them ..which she did generously 13. I get to the house and now everything goes wrong...not only is my shower COVERED IN MUD..but NO HOT WATER...and OUR SHOWER DOESN'T WORK!! 14. After multiple calls, Cool Air sends a plumber to our house at Friday 7/8PM (same guy that came at night while in DC and the only good person of this whole situation)...After reviewing everything he said that the bad part of tankless heaters is they can negatively impact the water pressure and this should have been taken into account..which it WAS NOT..so after 2.5 hrs a trip to Home Depot we get the main shower working..but little to no hot water 15. Over the course of the next week+ and multiple visits, having to buy new pieces for all showers and new faucet for the kitchen we have semi-hot water...also the only honest plumber there who was cleaning up everyone else's mess asked me one day..." why didn't you just install a "low boy" (a wider but shorter 50-gallon tank that would allow it to be raised) and a sump pump for half the cost of the tankless...can you imagine my face??? when I told him that was never presented to me as an option...he just shook his head 16. Hot Water...Not even near instant...on average (and yes timed), it takes almost 2 minutes for our bathrooms to get hot water...and we live in a 1300 sq ft house mind you! 17. Now if anyone does anything water-related at the same time...the other person gets dribbles!!!...so want to wash your hands while the dishwasher is on...good luck..washing machine...same .18 Icing on the cake....they never came back to put the cover on the outside piece of the tankless heater...my kids have nearly burnt themselves on the exposed piping and believe me if they do or a neighbors kids does litigation is on the horizon 19. I have called multiple times asking for someone to come back and install the cover, fix the issue, switch out for a low boy and sump pump..called and asked for the owner...no one returned my calls..no one followed up...it has been almost 3 months"
