"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, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.
