"So many choices when your looking for a company to service your heating and air conditioning needs. When we reached out on social media for suggestions for a reputable and reliable company so many people highly recommended Advanced Mechanical Services that we wondered if it was for real. Well now you can count us among the believers. From the moment Deena took our phone call till Rob and Ian arrived at our home and completed the work on-site, these incredibly talented and professional people did their job on time, as promised, with courtesy and knowledge and quickly identified and fixed both our heating and air conditioning issues that three other companies that we paid big money to in the past could not figure out. Their reasonable bill for quality work was another surprise. And they were COVID compliant and respectful with masks AND gloves which made us feel comfortable (as senior citizens) having them come into our home to do work."

"Extremely professional and knowledgeable service. Colby and Eli came out for an estimate on Tuesday and came back Friday for service. We walked through all vents to be cleaned and discussed the antimicrobial treatment. We had just bought the house and the ducts were never cleaned. They individually cleaned 24 vents and treated the system in just a little over 3 hours. They talked us through the whole process and showed plenty of before and after pictures. Would highly recommend!"

"I called first thing in the morning on June 30th, as I had been without hot water since the previous Friday night. (Good thing it wasn't winter!) They not only came out within an hour, they secured a new unit and installed it the same day! That included emptying the old unit, removing it and installing the new one. The job was done by mid-afternoon.
They gave me a quote over the phone, and billed me the same amount. I was very pleased.
Last summer they installed a new central air unit for me, did a great job then as well. I just hope the furnace isn't going to go next! But if it does, I will know who to call.

"Went very well, considering I needed my furnance fixed on a Sunday. I was able to call up at 7am and the tech was out to my house later that morning. Juan did a great job, fixed the problem and explained to me what he did. I would hire this company and ask for Juan if you have any HVAC needs."

"It went very well. The problem was fixed completely. I'm very satisfied. I thought the problem was simply a defective pressure relief valve. Not the case - the problem was a water logged expansion tank. Joe drained the system, installed a new expansion tank, a new automatic water feed with back flow prevention, a new 30 psi pressure relief valve, and a new automatic air vent. All the replaced components were old, so it made good sense to me to replace them. Joe even installed shut-off valves on the water feed and expansion tank line so that if new the expansion tank ever becomes defective, it can be replaced without having to drain the system. When everything was installed, Joe refilled and purged the system and thoroughly tested it before leaving. I am completely satisfied with the worked performed. Excellent work and good value."

"I hired northeast heating and cooling to replace my aging heating A/C system. This was a fairly large job, seeing it was a Multi floor house with two independent systems running both upstairs and the main floor. They also explained to me how adding a heat pump system to the house would help make heating my house less expensive during fall and spring. They replaced the entire upstairs duct work and reconfigured the entire house to run balanced and efficient. I couldn't be any happier with the work that was done in the house I would highly recommend them. Thank you Guy's for your hard work and dedication to get this system working amazing!"

Air Conditioning questions, answered by experts

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill.
