"I Called to get an in person quote for a tankless water heater flush and left this job with a whole house filter and a fridge connection. When Michael first arrived we inspected the tankless unit and tested the water to conclude flushing was not my best option. He then walked me through my options for home filters and we decided on a Halo system. Michael was very well educated on the subject and gave me the best value filter for my needs. He installed the unit the next day in less than a few hours and left me with a flawless work of art. I couldn't be more impressed with the professionalism he brings to this trade! I also requested to hook up a fridge and he did that in what seemed like 30 minutes. He will be the only plumber I call from now on!! Thank you Michael!!!"

"110% recommend Calclimate HVAC for anyone who needs heating and cooling services in the Burbank area. I recently had them install a new HVAC system in my elderly father's condo, and I was very impressed with their work. The system hadn't been turned on in decades, so it was in pretty bad shape. Calclimate's technicians were professional and knowledgeable, and they did a great job of assessing the situation and recommending the best system for my father's needs given that there are no natural gas hookups and all appliances run on electricity. They were also very patient and understanding. The installation process went smoothly, and the technicians were very clean and organized. They also took the time to explain everything to my father, so he understood how the system worked. I'm so grateful to Calclimate for their help. My father is now comfortable and cool in his condo, and he can finally enjoy the benefits of central heating and cooling. I would highly recommend them to anyone looking for HVAC services in Burbank."

"Darrow and his team did an excellent job! During a 100+ degree heat wave, our 2nd floor A/C failed. My prior A/C man had recently retired and I was scrambling.... reviewed Angie's List and made several calls. In several cases, I found myself as caller #10 in the queue. Darrow took the call personally, however, and was able to see us late that day. As a businessman I'm used to moving slowly, assessing, considering alternatives, etc. On this occasion there was no time, had to go with my gut. Mirsky Heat & Air really came through. They spent several hours (6-9pm) testing different options but ultimately found the compressor required replacement. They were able to return a day later and install the replacement. Their price was fair, Victor (his associate) was extremely knowledgeable, their work was first rate... and their response during a crisis was a life-saver! We highly recommend Darrow and his team... they're the Real Deal!!"

"This is the first time in many years that I have signed in to Angi. I saw that I still had this pending review to complete. Let me just say, this company was excellent. Would hire them again for a central aircon and heating install project. Middle range price but I think excellent work that you can trust."

"Everyone at Baltica was responsive and eager to please.  Calls and emails were returned punctually in every instance.  Everyone I communicated with was professional and accommodating. 
I called initially to discuss moving to a tankless water heater, but a personal review of my property showed that it was not possible.  Kevin Phidayev, with whom I made the arrangements, was eager to accommodate my product needs, financial needs, and scheduling needs.  Kevin was ultra-responsive to every call, email or request.
The installer, Marius, was particularly pleasant.  He showed up on time every time.  He looked professional, was knowledgeable, and he got the job done on time.  He was happy to accommodate my neighbors in the condo who would be without water for a brief time. Marius left my home clean, and he protected my new floors from damage. 
To be honest, I did not do any comparative shopping for pricing purposes because I was so impressed with my initial contact with this company.  I got all kinds of upgrades I never knew existed.  Marius installed a pressure relief valve, new water valve, new stainless steel flexible water and gas supply lines, and new double earthquake straps, among other things. I have learned from bitter experience that you get what you pay for.  If this water heater seemed costlier than I expected (my only "B" rating), in the end I believe I got my money's worth. 
The level and quality of customer service is unique in my experience.  Truly outstanding.  I have already referred business to Baltica, and would do so again without hesitation."

"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."

Install Boiler FAQs, answered by experts

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

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.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.
