"Alex was really nice and knowledgeable about our broken AC. We did pay the $89 service fee for the evaluation. What caught me off guard was the quote for a new Amana HVAC Unit - 26K! I mentioned that I need to get a few other estimates before committing. In response, Alex said that most people find out that his prices are competitive. I would have preferred that Alex said, "Great idea! That's a lot of money and it's always a good idea to get a 2nd opinion"...or something like that. After consulting 2 other family-owned businesses with stellar reviews, we were quoted prices that were 10 to 12 thousand less than One Hour. The equipment was the same, if not even higher efficiency. Definitely shop around before committing."

"Heart is absolutely amazing! Look no further, as Heart is who you should choose to work with! They are very professional, punctual, and do everything right the first time. We have a couple of different areas Heart helped with, and so this review focuses on the HVAC work we needed, beginning with replacing our rooftop package unit. Every single person is phenomenal to work with, and very knowledgeable; starting from Mike setting up the appointment, Roberto coming out for the diagnostic, and then the multiple teams with Cody, Blake, Steven, Collin, and Cory working to get our unit replaced! I know it was much more involved than initially thought, and these guys were here doing all that they could to get our heat up and running again! They offered us heaters to keep us comfortable, and communicating and explaining what was going on every step of the way! We had an issue with the filter, and so Steven, Collin, and later Cody, came back a different day to create larger return vents for us to be able to replace air filters inside our home. They helped us so much, and removed shelving that was in the way too! We also needed our electrical panel upgraded, and so Cory will be helping us with that (thank you Cassandra for getting that reschedule). Heart also was able to have all of what we needed financed under one bill, which was a huge help! I cannot imagine going through the HVAC and electrical replacement with anyone else; these guys made it easy on me and kept my stress level down. My only regret is not having found them sooner back when we needed our water heater replaced. We will definitely keep Heart for any future issues we have, and keep with the membership program to have areas checked out regularly. Thank you to everyone at Heart--you all are truly amazing and we appreciate you so much!"

"Behold Heating &Cooling diagnosed by furnace issue and correctly recommended a new furnace due to rust and leaks. Their bid was the most competitive and the customer service was outstanding. They were extremely courteous and followed up on all issues. We ended up with a fantastic new high efficiency furnace and new AC units with state of the art controller/thermostat controls. We are very pleased with Gilles and his crew."

"I would suggest you drop all other services and go with this one only. This service man is far beyond the skills and service of all others. I had one show up in car and a back pack. He looked at and said he would send a quote ?????? My furnace is out , its late and the temp outside is 0. Tony Bertolini repaired it less then a hour with no parts. This is a man that knows his S!!! and is more than worth his charges.When the weather starts to warm up I will call him to install a new one . [ I will call no one else .}"

Heating and Air Conditioning questions, answered by experts

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.
