  PhD Heating & Cooling helped us finally resolve a boiler and zoning issue that we had been dealing with for years. The system never worked correctly, zones were inconsistent, and no one could get it fully sorted out. Over the years, several other companies came out, tried different things, and left without actually fixing the root of the problem. It was frustrating and exhausting. PhD approached it differently. This was not a quick or easy job — they came back multiple times, tested the system thoroughly, and didn’t walk away when new issues showed up along the way. It ended up taking about four days of their time to fully dial everything in. We did need to pay more as the scope became clearer, but unlike others, they actually finished the job instead of giving up. Now all zones work properly, the system runs smoothly, and everything finally makes sense. If you have a complex boiler or zoning problem that others couldn’t solve, PhD Heating & Cooling is the company you want.

  We have used PhD for our hvac system for over a year now. Top quality work, and reasonable prices. Phd fixed issues another hvac company couldn’t. I highly recommend phd and would take his work/service over any other hvac company. You won’t be disappointed with his response time and work.

  PhD Heating & Cooling did an outstanding job on our boiler system. This was not a simple repair — several other companies either refused the job or could not properly diagnose the issue. The PhD team took the time to fully understand the problem and explained everything clearly before starting the work. They handled a very complex repair that required experience and real technical knowledge. The work took the entire day, and they continued working despite extremely cold weather conditions. What impressed us most was their persistence and attention to detail — they didn’t rush and didn’t leave until the system was operating correctly and safely. The final price was very reasonable and actually lower than several other quotes we received, especially considering the difficulty of the job. PhD Heating & Cooling is a professional, honest, and highly skilled company. If you need serious HVAC or boiler work done right, don’t waste time calling around — these are the people to hire. Highly recommended.

  Our furnace stopped working suddenly tonight (Friday) and the weekend forecast was for below zero temps. After calling multiple companies who would not come out until a later date, PHD came out the same night. They were onsite within an hour and got the unit working very quickly. We were very impressed with their professionalism, promptness and concern for our situation. They are very knowledgeable. Outstanding service and value!!! We will definitely call them again!

  The service was completed promptly although Dmitrov seemed kind of cranky. What was less good was them telling me they were sending me to collections 4 days after the service, which was the first day I saw the invoice.
