"The owner Mike was able to come into our house and diagnose a complex environment problem that was causing our heater to run continuously.  (This problem was not solved by several other HVAC contractors)  During Mike's analysis, he performed the standard maintenance routines to validate the HVAC unit was operating properly.  From there, he looked into what other conditions existed into the house that were causing the unit to not sufficiently heat the house.  After a thorough analysis, he was able to then install the home air quality devices onto our existing HVAC unit to dramatically improve our indoor air quality.  With these additional components, we have been able to control our indoor humidity and provide fresh air ventilation automatically.  All of this was set up on an internet capable control module so we can control the entire system from a smartphone.  As a result, the HVAC does not run continuously to heat the house, and now operates very efficiently.

 Mike has been incredibly responsive in the time that we have worked with him.  He has responded to calls, email, and texts very quickly.  His initial service call was on a Sunday afternoon and we have also completed a facetime conversation as part of the diagnosis.  After the initial installation, we had an issue with the equipment itself.  Mike quickly responded, worked with his supplier, and they resolved the issues through the product warranty in the matter of a day. Through the entire process, he has taken a lot of time to completely explain to me what was happening and provided detailed recommendations.  His level of customer service, responsiveness, and communication has been outstanding.

I would definitely recommend Mike and Unique Air for HVAC and home comfort systems."

"The contractor performed an outstanding installation. The first visit, he assessed the work to perform, then walk me through the process he would perform. He offered various units to accommodate my requirement before I decided on the best option. On the day of the installation, he arrived on time, took the necessary safety precautions, did the installation and then walk me through the process of what he performed and showed me the operations. His quality of work (A+) and the cost (A+) met our expectations."

Install Boiler FAQs, answered by experts

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.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.
