"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

"The service was wonderful, bar none.  He gave me a firm and complete estimate. Even after the estimate he was able to provide a slightly larger (more effective) cooling system at no additional cost.  Also, he never recommended anything outside of what I saw as appropriate for my situation.  My very old installation could not handle the installation of a Puron (sp?, newest technology) system without significant degradation of performance and longevity so he recommended I what I believe was an appropriate replacement unit.  My previous (long ago) experience in the HVAC industry only confirm everything Mr. Mirsky ("Darrow" as he probably prefers) told me.
All service was completed on-time(overall), on-budget, and on-time (within the service day) without issue.  The people assigned both at the preliminary inspection and installation were very kind, courteous, knowledgable and professional about the installation.
My opinion: if you need HVAC services within the service area Mr. Mirsky covers, call him in to do the work, NOW!  I have found this level of service within the LA are to be rare. He may not be Irish, but it is not unlike having a Leprechaun visit given what a find Darrow and his team represent!
My apologies to Darrow for not posting this earlier!

"Carlos Chamorro from Southland Heating and Air Conditioning was very helpful and explained the details very well. He was on time and very friendly. He was very professional. I had a very positive experience with this company. They confirmed with me and gave me a half-hour window to meet up with them. Great company so far."

"Joe was amazing. He not only found a better A/C unit than the one we we were looking at (for even less than what we had originally budgeted) he also installed it perfectly. When we had a small issue (turned out to be low FREON) Joe came, replaced a valve and fixed it perfectly. Our new A/C is working great and Joe has been amazing to deal with. We would hire him again in an instant."

"The access panel on the unit was slightly bent as was the unit. Instead of repairing the installers taped it up with duct tape. The panel fell off and I had to call for another service man to come out and correct the problem. The second technician did a much better job."

"Installation was smoooth, it was done within a day. There was high pressure sales involed which I succumbed into as the sales guys were saying that I had fiber damage in my ducting and since I have kids in the house they said that it was very crucial that I do the change now. It was my fault to not do any more pricing research hence I was a bit gouged."

"We needed a new heater and decided to also add A/C - went great. The sales person was very helpful and knowledgeable about our options and helped us choose a best fit. We chose a more expensive option because the maintenance and repair on the Carrier solution was the best. The Carrier company who provided the equipment also provided a good financing fit. The installation crew were a great bunch of folks, efficient, friendly and left our job site immaculate."

Install Boiler questions, answered by experts

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

Most installations take 2-5 days, including old system removal and setup.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
