We first met with Said and he is very knowledgeable and only company to be able to give a price before leaving. Installation day was setup and done very clean/smoothly with the A Plus team. Great job guys. Definitely recommend if looking to get a whole home generator installed.Posted on Google![]()

Replaced an aging air conditioning system, furnace and hot water tank with new Trane AC and furnace and a tankless water heater. And oh yes a new thermostat and electronic air cleaner. Irfan was excellent at outlining the products we needed and explaining the differences. He was always prompt, courteous, and open to any questions. The installation was handled very well by three of the best installers we have had into the house. They were careful not to damage anything and took care to keep the house clean even though the rain continued most of the day. Their professional attitude and experience made a huge job go smoothly. We could not be happier with the A Plus team and of course we love our new Trane products. If I had to give them a grade, well, it would have to be a solid A Plus!Posted on Google![]()

Had annual furnace service from A Plus Air Systems this week. This year it is Tashi's turn. He did an excellent job: arrived within agreed time frame; called ahead inform his ETA; did detailed checkup, testing and cleaning of the furnace, and passed me useful information on furnace filter selection. All are good and satisfied with the service. I have been using the service from A Plus Air Systems for over 10 years. Good experience outweighs not so good ones by a wide margin.Posted on Google![]()

A Plus Air Systems have been servicing our air systems for over 20 years. For the past 20 years or so Aziz Koya has been our Service Specialist. Initially we just had our furnace and air conditioning system looked after but about 15 years ago we got an electronic air filter system from A Plus then about 5 years ago we had A Plus replace our hot water tank with a tankless water heater. Through it all our service from A Plus has been superb. While our prime contact has always been Aziz, he is obviously well supported by A Plus and particularly by Steven Abraham. The work done has always been timely, thorough, well executed and fairly priced. We have never felt pressured to buy anything; when something has been deficient, Aziz and Steven have presented the alternatives to us and allowed us to make our decision. We highly recommend Aziz, Steven and A Plus! Recently we moved into an apartment. On September 22nd, 2026 Daniel from A Plus installed our new through the wall AC unit. He arrived on time, did a superb job of quickly and efficiently installing the unit inside and out and cleaned up after. We highly recommend A Plus and Daniel! They are worth every penny!+1Posted on Google![]()

We recently had a new heat pump and tankless water heater installed by A Plus Air Systems, and we couldn’t be happier with the experience. They offered us a very reasonable price with a **3-year, no-interest financing option**, which made the investment much more manageable for our family. A Plus Air Systems is a great family-run business, with **Said Mosmer and Rashid Popal** leading an excellent team. Everyone we dealt with, including **Mohammed and Noah**, was professional, knowledgeable, friendly, and committed to doing a great job. It’s refreshing to deal with a company that genuinely cares about its customers and takes pride in its work. I will definitely be calling A Plus Air Systems for all of our future HVAC needs. **Thanks to Said, Rashid, Mohammed, Noah, and the entire A Plus Air Systems team! Highly recommended!**Posted on Google![]()

Efficiency has become one of the most misunderstood parts of HVAC decision-making. Newer systems can reduce energy costs — but not always in the way people expect…

Understanding what your system is telling you during each season, and why shoulder season matters most, is one of the most effective ways to reduce breakdowns, manage costs, and extend equipment life.

In our experience at A Plus Air Systems, systems are rarely replaced because someone planned ahead. More often, they’re replaced because something failed at the worst possible time. That’s when options narrow, costs rise, and decisions feel rushed. This guide is meant to slow that process down and give you a clearer…
