"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!

"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."

Install Boiler questions, answered by experts

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs.
