Furnace installation and service We recently had a new Daikin furnace installed by A1. We did obtain 4 quotes from various companies however we decided to go with A1 because of their professionalism transparency and a personal approach during the initial discussion. Installation was quick with guys showing up on time and leaving the place clean. Big shout out to their service, we had called A1 twice and both times service was superb. We’ll definitely continue to use A1 and highly recommend their services. 

Business response:

Thank you for choosing A1 and taking the time to give your feedback. We always look forward to building relationships with new clients and look forward to your next service appointment.

Furance, Air Conditioner and Hot Water Tank A1 looked after our 1994 furnace for years and gave us great service. When the furnace needed replacing, we knew A1 would be the ones to put in a new one for us. Scott came down and went through everything with us: different options of furnaces, prices etc. The price seemed very reasonable, so we also bought from them a new Air Conditioner and a New Water heater to replace the rented one we were paying for again and again. The new furnace is running very smoothly and I can't wait f... read more

Furnace and Air conditioning installation Our AC broke down last summer and the furnace needed repairs and it was 15 yrs old Rather than repair we got a price for a whole new system. A1 was very competitive in prices and helped us get all the govt rebates that were available which was very helpful. They crew was very professional and their office really pushed to get our energy audit and install done on the same day. Very good experience 

Business response:

We are so glad you had a good experience with us! Thank you for posting a review and sharing that experience with others...looking forward to a lasting relationship!

New AC and furnace installation Dispatch 59687. I had a new AC and furnace installed (Daikin), and I was very pleased with the professionalism and quality of service from start to finish. I obtained several quotes and A1 was the most knowledgeable and straightforward, and provided two clear options that suited my needs. I am very happy with the quality of the product and installation, A1 provided exactly what was promised with no surprises. I would certainly recommend A1 to anyone. 

Business response:

Nobody likes surprises when it comes to new equipment in the home. We are happy to have given you such a great experience and kept up with your expectations from start to finish. We look forward to exceeding these same standards with future service appointments. Have a wonderfully warm start to fall!

New Furnace installation I had a Daikin furnace installed by A1 air cond./heating this week. They sent a very experienced salesman who patiently explained everything in great detail, answered all my questions and quickly arranged the installation on very short notice. The installers came on time and were efficiently done in 3 hours. So far I'm happy with my new furnace and A1's professional service. I never thought I would enjoy looking at and using the smart thermostat that A1 provided... NEST is fantastic. 

Business response:

Thank you so much for your review. If think the NEST Thermostat is fantastic you should look at the NEST Protect - it is a Smoke and CO Alarm all in one that also sends an alarm to your cell phone so even if your not home you know if there is something wrong. Here's the link... https://nest.com/ca/smoke-co-alarm/meet-nest-protect/

A/C Unit malfunctioningl Our A/C unit was not working, called A1 and Casey (spelling?) was here in about 40 minutes, he diagnosed the issue immediately and had it fixed in just a few minutes. There was a time delay function on the unit that was malfunctioning and redundant that he was able to bypass and get it working with no extra parts, and only billed us the $99+tax diagnostic fee. This unit is probably around 20 years old and they could have attempted to gouge us for a new unit or unnecessary repair costs but he did it q... read more

Business response:

Thanks for the review! We're thrilled that your thrilled! Our goal is to do what is best for the customer - you know the time is coming to replace the AC but if you can get another season out of it for very little money why not...we're here if you need us.

Two new Daikon furnaces We had used two other furnace companies to service our 2 furnaces. The second company had to trouble shoot repairs several times and never identified the problem or found solutions. They suddenly closed down so we chose A1. That same problem was identified and solved in a 30 min visit plus a recommendation to for future parts and /or new furnaces. We were hooked. AC's were serviced and put under the Super care program which is great service insurance.. We were now happily 'caught'. After being patient... read more

Business response:

A1's continued success is built on special relationships with clients like you. We want you to know how much we appreciate your business and we plan on being around for many years to come!

new furnace and new air conditioner We moved into our Watertown house about nine months ago. We knew the furnace and air conditioner were about 20 years old but we thought we could get a little more time out of them. The air conditioner died two weeks after moving in. We waited until May to call A-1. Upon inspection, the furnace was red-tagged. We replaced both furnace and air conditioner. All five people that we dealt with from A-1 (original inspector, sales person, two installers, follow-up inspector) were courteous and he... read more
