An annual inspection allows a technician to tune your equipment as well as identify issues before they can cause major damage or even intermittent lockouts..

Gas Fireplace Annual Maintenance

The best time to service the fireplace is just after the ehating season. This way the glass is nice and clean over the summer and the unit is ready to go for fall.

I called Furlong HVAC Services to get a quote for two new thermostats and Phil advised me that I wasn't using the existing thermostats properly. He provided easy to understand instructions over the phone and there was no charge. This is a very honest approach to running a business. I would highly recommend this company.

Furlong HVAC recently updated the air conditioning system in our home. (They have previously serviced our heating system). From the initial estimate until the completion of the job, Phil and Curtis were totally professional and met all of their commitments, including bringing the project to completion on budget. The project had unique challenges as the installation needed to be made in a century old home. Phil and Curtis were tireless in their efforts to successfully address those challenges. Their communications were always clear and timely. I would recommend this family run business without hesitation.

Furlong HVAC is who to call if you have air conditioning issues. We were in a heatwave and they responded to our request the same day, even though they had a full schedule. Our air conditioner unit was fixed that day and for a great price. Thanks so much Furlong HVAC!

My fairly new air conditioner unit failed on the hottest weekend days of the season June 26th & 27th 2021. I text & called my regular service person at Reliance Home Comfort. More than a week later I have not heard from the technician from Home Reliance. I contact a couple of other local HVAC service companies in the area. Both companies returned my call and confirmed they could book a service call within a day or two. When I spoke with Crystal at Furlong HVAC and she said her technicians were working in the Lyndhurst area. I said i was a neighbor and close by and lived on their return home route. Crystal said she already had them booked for an enroute call, but she said would talk to them and try and squeeze me in. Phil arrived within an hour of the call, came straight to my home while enroute home, investigated the problem, found the source of the problem and promptly fixed it. How COOL is that? and now we are cool too! .. thank you Crystal and Phil for your wonderful prompt service. It's exceptionally nice to know new neighbors and even better when we can help small businesses in our community. I wouldn't hesitate to recommend Furlong HVAC for the best service ever! Thank you! Karen Winter - a very cool neighbor! :)

Your technician just left my summer property in Gananoque and did a great job at getting my ductless AC system up and running. Thanks for fitting me in on such short notice.

Furlong HVAC is very responsive. We called them initially to fix our AC unit, which was quite old. In the end, a new unit was needed and they reduced new unit price, by the amount I paid on the initial service call. All in all, I would highly recommend this company. Curtis was very polite and explained everything to us very well.

Outstanding experience all around. Phone was answered by a real person who was pleasant and professional. Appointment was made promptly and we were called when Curtis the service technician was on his way. Curtis was on time and stayed until the job was completed perfectly. We will definitely use them in the future!! Thank you!
