We called a company that previously maintained our unit the last couple of years. The personal had changed as the technician who had been here before and we requested the new operator said that she doesn’t see that he works for them anymore , but someone else will get back to you. After 2 days of no return call at all.
So I called Endless Energy and they very cordially ask me about our problem, the type of A/C unit we had, it’s age and what was going on and I set up the appointment.
They via a text message reverified the appointment.
Gavin arrived and proceeded to troubleshoot the problem and when he said right away he’s seen this problem before and he seemed very confidant he could help us.
Gavin explained everything to us in a very distinct manner and gave us options with respect to getting the unit to work today
(stuff not done under yearly maintained visit) but also explained that doing a couple of other things that seemed reasonable to do eg we needed a new capacitor and we had very dirty coils (after he finished he also showed us the before and after pixs of the outside unit after he cleaned it as the clogged dirty coils looked like new after he cleaned them).
The price he quoted us was very reasonable. He stayed later than 5:00 pm to finish as he came at 2:30 pm so that it could be completed that day. Before he left I asked him if we could make an appointment to have a regular maintenance and have our air filter changed, but he basically said we didn’t need a yearly maintenance as he checked the other vital parts and proceeded to even changed the air filter for us also.
Finally I have to say he did too good of a job as now the unit is blowing the air so “COLD”coming out of the floor registers my wife and I had to put on a sweater to stay warm. The thermostat went from 85 to now it’s freezing in the house. It is definitely blowing colder now than I can remember going back years before.
I would highly recommend Gavin as a very polite, competent, well-schooled in his understanding of his craft and especially the way he explains issues related to our air conditioning system.
He is a very knowledgeable technician!!!!
I’m so glad I made that call to Endless Energy in Marlborough.
They will be back next year for our yearly maintenance also.
