Our HVAC water pan was nearly overflowing on the coldest day of the year. I called ABC at 11 am, Mike the tech said he'd come at 1 pm. But called back to say he could come earlier. He arrived at 1230, took time to diagnose the problem (clogged drain pipes and calcified filter), gave me a time and cost estimate to replace our drainage pipes and filter. He had all the parts on his truck except one. He replaced all the pipes by 230, and came back at 4 with the extra filter. Heat is back to normal and water lines are clear! Excellent repair and stellar customer service! Highly recommend

I had an issue with my HVAC unit where it kept shutting off whenever the temperature was in the 80s. After Mike and his crew came in for inspection, he found out that the compressor was pretty much done and needed replacement.
Mike was able to find the exact part number, ordered the unit, and installed it without any issue in the middle of an HVAC shortage. Really appreciate the 5 star service he provided!

The air conditioning unit in my condo just randomly stopped working in the middle of what is already turning out to be a really hot summer. I found ABC 24 Hours Heating and Cooling through a Google search after calling a couple of other companies that didn't even answer the phone. Michael arrived within 30 minutes or less. He looked at the unit, figured out the problem, and explained exactly what it was, and what he needed to do to fix it, as well as quoted his price up front before starting the repairs. The price was much lower than I was anticipating. The service was thorough, and Michael

Follow-up again: Mike was able to beat the competition in both price and turnaround time for I installing a new water heater in my house. Very happy.

I spoke to a very rude gentleman as instructed by the warranty company provided for a property I manage. He spoke extremely fast, curt, and rudely to me from the start of the call, and when I asked for clarification on what he said, he made it seem like I, the customer, was inconveniencing him.
Anyway, so do not be fooled by the name, they are not actually 24 hours as stated by the rude gentleman I had gotten. Okay, fine, so I ask to go ahead and set up an appointment and I was told they can't even set up an appointment until Saturday, two days from now. This is a no-heat call and the temperature

Had an issue where our furnace was leaking gas and the fire department had to come to our rental property to shut off our gas. Obviously this was an emergency so I called ABC afterhours and was greeted very nicely and courteously. They came out and assessed the situation, advised me of what they needed to do and how to remedy the situation. It was determined that I needed to replace my whole system and because it's not cheap, I obviously called other companies for different quotes.
ABC will beat the competition prices, just show them the other companies estimates. This alone as well as their
