WHAT OUR CLIENTS SAY...
Jim Blake of AJ Michaels has been a pleasure to work with and appreciate his professionalism and competence in both repairing a heating issue as well as an AC issue. I have engaged many HVAC companies and techs over the years but have finally found someone that can get the job done and stands by his work. Thanks!
Yaakov Feinstein
Awesome install of multiple mini-splits! My house has some pretty high walls, and they tackled the job perfectly. Very happy customer here.
Jack Rodriguez
We used AJ Michaels maybe 9 years ago to replace out AC/Heating Unit. They id a great job. This year, we used them to install a Mitsubishi split in our Master Bedroom. They were professional, affordable, polite, timely, pretty much everything you could ask for. We'll use them again if a project comes up.
Laure Ruth
The new heat pumps work well, installation looks great. Workers were prompt and efficient. I will certainly use this firm in the future.

HOW WE HELP
At A.J. Michael’s we provide complete HVAC system service, whether you need your unit fixed fast or some regular maintenance to maintain peak efficiency.
Our experts make a careful inspection and then explain the best course of action for your system and home.
We’ll explain details other contractors don’t. Take the Seasonal Energy Efficiency Rating (SEER) number, for example. Someone might try to sell you a heat pump with a SEER number of 18, which is very good. But if your ductwork isn’t the right size or configuration, your 18-SEER heat pump will perform like a 10 – and you’ll be disappointed. We’ll inspect your entire system, to ensure that doesn’t happen.
Your ductwork may be wasting energy. We can locate and fix leaks from the inside with the cutting-edge Aeroseal duct sealing system guaranteed effective for 10 years.
FREQUENTLY ASKED QUESTIONS
Of course if your unit isn’t working, you need a technician to fix it ASAP. But, there are many other indicators that your HVAC unit needs repair or maintenance such as experiencing uneven temperatures in different areas/rooms or certain rooms can’t get to a desired temperature level.
If you are hearing loud equipment noises, receiving higher than usual energy bills, you haven’t changed a filter in 3 months or there’s fluid leaking from your equipment, you may need your HVAC system serviced.
What are common problems/indicators that an HVAC unit needs repair or maintenance?
What kind of maintenance is recommended and how often?
Typically, it is recommended that each system (heating and/or cooling) be routinely maintained once a year. So, a house with central air and a furnace/heat pump would be serviced once before the hotter months and once before it gets cold.
What are the benefits of having your HVAC system serviced?
Proactively taking care of your HVAC system offers a range of benefits such as:
Extends the life of the unit
Maintains the efficiency rating of the system
Lower energy bills
Discover potential issues before they become a serious problem
Ensure the system is operating safely (carbon monoxide levels and combustion-related issues with oil and natural gas)
Company service agreements often include discounts for parts
What are common issues to fix on residential HVAC systems?
While every system is different and at A.J. Michaels we customize all our solutions, there are some common problems we frequently encounter and have experience fixing such as:
Dirty air filters for furnaces and heat pumps
Dirty coils in heat pump air handlers
Cracked heat exchangers in boilers
Improperly tuned oil furnaces
Leaking radiators
Heat pump compressor failure
We specialize in maintenance, repair and service for almost any residential HVAC system.
