"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

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.
