"Air-Tech installed a 3 zone Mitsubishi mini-split system in our home this in September. We got quote from five companies for the system and decided on Air-Tech because of Larry’s knowledge and experience. The bid from Air-Tech was competitive. Air-Tech was not the lowest priced bid we got, but quality is worth paying for. I can say that out of all the HVAC companies we have worked with over the years Air-Tech surpasses them all by leaps and bounds. When I say this, I am coming from a place of experience. We have built our own house and we come from a family of architects and builders. We also had just finished working with another company (that shall remain un-named) around the same time to replace a different central air system. That other un-named company completed the job late, charged a higher price than what they proposed, and left our house and property a mess. Air-Tech however was knowledgeable, prompt, clean, trust-worthy, and professional. Larry even went out of his way to get our project done faster than their schedule should have allowed at the time. They were scheduling months out when I called during the big heat wave of the summer, but he got our project done in three weeks anyway. I had explained to Larry that we were without heating or cooling at the moment and really needed help. I did not tell him that the urgency was because my terminally ill mother was coming to stay with us and she needed good climate control. While Larry didn’t know about my sick mother, he was able to understand the urgency in my tone I suppose. Larry put an extra crew on the job and oversaw the work himself. The fact that Larry came through for us made such a difference in our lives at the time. I am sharing this story to demonstrate that at the end of the day Air-Tech is a company of people who want to help people and on top of that they are excellent at doing what they do. PS. I also enjoyed the Holiday Card they sent us this year."

"I needed an oil change done on my Mercedes. Dave the owner made sure he had all the right spec fluids for my car when I go there. Connie the friendly receptionist was friendl and efficient.. I was in and out quick all fluids topped off, and potential problems brought to my attention, no sales pitch just good old fashioned honest people. We'll do business with them again. Highly Recommended

"It went well. He was on time. He didn't find anything wrong with my system. He said the amount of freon in the system was just right--not too much and not too little. I liked that almost no freon appeared to leak out when he connected his equipment to test the level. He spent a lot of time with me and answered all my questions. He gave me an estimate for the cost of installing a new system. I think he hoped I would buy a new system, but I did not do so. I would buy a new system if I could convince myself that the  electricity savings would pay for the system within a reasonable number of years.

"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."

"Dave was very efficient and knowledgeable. He was able to supply my quote before he left. I look forward to working with Southland heating and air. Follow up: I made my decision and signed the contract. Best decision I could have made. They were thousands of dollars less for the exact same equipment than 3 other companies I got estimates from. When challenged none of the other companies could revise their estimate to even come close. Southland is a Mitsubishi diamond dealer so I got full Mitsubishi warranties plus 1 year from Southland of parts and service. The day the installers arrived, on time, it was raining. Jamie and Ricardo used the utmost care to protect my home. They covered the floors, moved and covered the furniture and made sure before they left that I fully understood how to use the remote and operate the equipment. I have attached a photo so you can see for yourself the way they carted for my home. The equipment works perfectly. I would hire this company again in a heart"

Install Boiler questions, answered by experts

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

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.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

Costs depend on issue severity, parts needed, and labor rates.
