"It started off bad because I had the water heater installed, submitted my paperwork for my rebate for the installation and then my rebate ended up not getting honored because the water heater that was installed didn't qualify for Spire's rebate. Turn's out that the water heater that would fit my location as well as satisfy Spire's rebate, I would have had to wait 5 to 6 weeks for that specific water heater so, the owner of Hosack's Plumbing cut me a check for the amount of the rebate and the amount over time that the new water heater would have saved me. Not the perfect situation but, that was a win win for me as well as Hosack's Plumbing because a good water heater was installed just not one that would quite fit the Spire requirements for the rebate! Hence we didn't need to take a brand new water heater out and replace it with another water heater that was just .05 UEF Higher!"

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"Frankly, I rarely give reviews but this encounter warranted it. Here we go: On a 100 degree, sweltering Saint Louis afternoon, my 23 year old HVAC system finally called it quits. I knew I was looking at a full replacement and a repair would simply cost more money in the long run as the replacement was imminent. I did my due diligence and got multiple bids. I contacted John Hively and he said he could make it out that night (it was already 6:00 when I contacted him!) He showed up just 30 minutes later and did HIS due diligence checking all the components of the HVAC system before offering his diagnosis, verdict, and the cost of parts and labor. He was incredibly knowledgeable and his proposal was very reasonable considering the extent of the project and he was very competitive against the several other bids I had received - not to mention his warranties were unrivaled. Now, this is where the story gets really good... Because of the heat and my staying at a hotel because my house was 86 degrees, he rushed the appointment... While everyone else was giving a 7-14 day approximation, he was back the next day to drop of equipment and then the following day for the install. From 72 hours of making the call I had cool air again. He estimated a 4-6 hour completion time and his *extremely professional* crew was done in 5. They gave me a run-down on maintenance procedures, double checked everything to make sure the system was functioning as it should be, and were on their way. I can confidently state that John Hively provided the best residential service of ANY kind I've received since being a homeowner. I won't even waste time with bids on any HVAC needs again because Hively Heating and Cooling is my new go-to HVAC service provider. Do yourself a favor and call John. - A very happy homeowner"

Heating and Air Conditioning questions, answered by experts

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
