"We hired them for a new HVAC installation during our home renovation, and we couldn?t be happier. The team was on time, polite, and very knowledgeable. They installed the new system flawlessly and made sure everything was tested and working perfectly. Great workmanship and outstanding customer service!"

"Expensive but showed up the same day as my call with everything necessary for the upgrade. Had the new system installed and producing hot water within 3 hours of arriving. Installer (Mario) was polite, conscientious, knowledgeable, informative, and pleasantly and intelligently conversational. Made the entire experience a pleasure."

"They were AWESOME. Same day service and quickly diagnosed the issue (blown transformer, since my furnace does not have a fuse). The guys were professional, courteous, explained what they were doing and why, and couldn't have been nicer. They finished the job quickly, and even installed the NEST which I had done wrong the first time, hence the need to call them. :-P"

"Joe was terrific. I called several companies and he had the best deal in town in that he did not try and sell me a bunch of stuff, but instead offered to service my HVAC and come back in 6 months for one low price. He also installed 2 new smart thermostats for me. He called me right back. Scheduled an appointment right away and showed up on time. The thermostats I had purchased (ecobee) were new to him and he honestly told me that but said he could handle it and he did. Plus he is a very nice family man to work with. Definitely use him again."

As a result of the professional expertise of Mr. Mathew Alba, a member of the family run business of Southland Heating and Air Conditioning and Mathew's clear explanation, good advice, honesty, customer friendly attitude, good suggestions, and help in obtaining energy rebates, enabled me to quickly eliminate other HVAC contractors to favor Southland Heating and Air Conditioning to perform and complete the work at my residence.

On the day of the job the workers were prompt, very organized, and everyone worked non-stop until the work was completed. Mr. Willie Torres, lead foreman and everyone on his work crew, from Southland Heating and Air Conditioning performed high quality work, were very efficient, and installed everything in much less than eight hours.  Considering the amount of work that needed to be done, I was very impressed.

This major heating improvement has already made a difference in the heating comfort, and it is certain that the energy savings alone made this upgrade worth every dollar spent.   As a customer, if I had to do this all over again, my first and last choice would be Southland Heating and Air Conditioning.

"Not only did the technician find what was wrong, he told me that the unit was in really good shape (after he got it running) and that it was good to go for many more years.  That's honesty for ya!  I know that IWAI is a little far from the westside of LA but I called Craig anyway because of the great job he did for another one of my clients.   The tech got out there within 48 hours and made some minor repairs to a unit that I was told would possibly need replacing.  My clients were thrilled at the low cost of the inspection and that it only needed a couple of parts to get it running like new.  They ended up buying the condo and are extremely happy.  But wait, there's more!  
(Second Job) I met Craig in January of 2015 when he came out to look at a heating problem in one of my client's apartment complexes in Beverly Hills.  This was an old building (1947) that had 3 gravity furnaces underneath the property.  All 3 were original and failing.  I got three bids to have them removed and replaced with new units.  One bid was just over $18,000, the other just over $16,000. Mind you, this was to remove three gravity furnaces, replace them with new gas furnaces, including some duct work, as well as do a complete new installation in the attic of the top floor unit.  IWAI's price came in approx. $8,000 cheaper than the highest bid!!! $8,000!!!!  I was skeptical at first.  I mean who wouldn't be?  An $8,000 difference?  But I discussed it with my client and we went with IWAI Heating and Cooling.  Not only did Craig do what he said he was going to do, but he started on the day he promised, and he finished on time as well!!!  The tenants had only nice things to say about he and his crew and no one was inconvenienced but for a couple of hours when an air return had to be installed in one of the lower units.  The job couldn't have gone any better and the price was outrageously inexpensive for the work that was performed.  My client was thrilled and so were her tenants, especially now that they had heat.  Thanks to Craig and his crew for taking care of this job with the upmost professionalism.  If you need anything regarding HVAC, call IWAI heating and cooling.  Have them come out and give you a quote; you'll be glad you did!!!

"Lost our heat on a very cold late afternoon. Called 3 places. NRG was the only company that returned our call. Sent someone within an hour. Determined that our 28 year old unit needed to be replaced. Benjamin spent at least and hour on the phone to order the new unit and arranged to have it installed the next day, Thanks to all involved. Curtious, punctual, and professional."

"Evening of Valentine's Day we learned our water heater had broken.
Called Bob & Marc the next morning and had an appointment of 3 pm. They were available earlier, but I could not get out of work any earlier.
Spencer was on time and got right to work. He was very professional, careful and friendly.
He assessed that the water heater was broken, drained and removed the old one and installed the new one.
He made sure that the TPM piping was exact, fit and would last. He was very helpful in explaining what he was doing and was even very helpful in providing advice on how to extend the life of this new water heater.
He cleaned up and all that was left was a professionally installed water heater that has been working great.
Thanks for the quick, friendly service (also be sure to use the 10% off coupon found on their  Angie's list page).

"Our outdoor barbeque/kitchen in the pool area was just done by Best Builders Group who was referred to us by a co-worker who hired them for his last remodeling project at his house and he was very happy with everything they did. Our remodeling project was a large scale remodeling project to our opinion BUT to Best Builders Group it was a normal size project and they provided all the required attention to detail and great working capabilities. We had some concerns on the plumbing & electrical but Zohar took care of all of them in a very professional manner. Part of the work was to build a custom fire pit and Zohar was always nice enough to do whatever we asked. All the workers on the other hand… always made sure to clean up & they never left the house without the cleaning task. The installations was done perfectly, professionally, clean and with perfection. This remodeling project came out to be such a wonderful entertaining spot of the house and I strongly recommend them."

Install Boiler FAQs, answered by experts

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.
