"We hired AC Dave to install a heating & cooling unit, after using them for our old unit's maintenance for years. It was a unit that. went on the roof, so installation was no small task. They did a fantastic job, kept the area clean, were extremely courteous, and we felt like we were hiring family to help us out. They pulled all of the permits which cost extra of course, but it saved us the hassle of dealing with the city and handled the post work city inspections."

"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."

"I was in need of a replacement system, but was really afraid of having people in my home during Covid. From the first phone call I was put at ease as I was informed that DNA will show up with masks, gloves and booties. I scheduled an appointment, and was told I would receive a phone call and/or text message 30 mins prior to arrival. Well, Andrew did not disappoint, he made sure to keep his distance and even offered to sit in the patio to go over some options. Once we sat down he educated us on some air filtration products. We were able to chose the system that fit our budget, and I fell in love with the Lennox pure air filtration. We decided to move forward and later that week we had the system installed. When I say they went above and beyond protecting our home from dust and debris thats an understatement. The had plastic on walls, drop cloths on floors, wore their mask, and gloves throughout the whole job. Once they left I didn’t have to clean anything up. Its has been a few months since the install and I can totally tell the difference of our air quality. I have recommended them to everyone."

"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."

Install Boiler questions, answered by experts

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.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

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.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.
