Someone from your company did a boiler maintenance for us last year and we were hoping you might be able to do it again. There's a bit of clanking once in a while so wanted to make sure all was well with the machinery.

I have a three story townhouse with two zones of heating/cooling. The outside air handers have always been a little loud but yesterday evening got much louder than usual, so there may be some kind of problem. The system hasn't been serviced for two years so it needs a regular servicing regardless. I am available Wednesday afternoon if that is a possibility, otherwise Saturday morning or sometime next week would work best for us. Thank you, Jennifer Elliott

Old gas HVAC - would like to change to electric HVAC.
Vicinity of Henry Street in Cambridge
Want to install central air conditioning in all 3 floors of 2-family in Cambridge. Also willing to consider replacing current heating systems (mixture of steam and hot water baseboard depending on the floor). Planning a renovation of 2nd floor in next few months, so that might be a good time to install ducts or whatever else needs to happen. If we stick with the steam heat on the 2nd floor we will need to move the radiators as we are taking out some walls. Main question: what choices for A/C, & should we install at the same time as 2nd floor reno?

We are replacing an old thermostat with a Nest E Thermostat, and have been advised that we need to increase the voltage on the R wire for the thermostat to 24V in order to make it work. Please send an estimate for the cost for this service. I prefer contact via email. Thanks!
