We have always been very satisfied with Supertech hvac, thanks to Kenny's thorough diagnostics. Recently he fixed our hvac when no one else could... He listens to our concerns and always goes the extra mile to make sure we are aware of the situation and happy with the solution. Couldn’t be happier with his work!.

SuperTech was absolutely the best company I have ever used from scheduling a same day appointment to having a wonderful friendly helpful technician fix the problem with our air conditioning system. I would recommend this company for everyone. Outstanding customer service and very reasonable prices for a great wonderful company.

Maintenance is important for your AC or heater because it helps protect it from breakdowns. Schedule maintenance for each system at least once a year. The best time for AC maintenance is in the spring before you turn on the AC for hot weather. Similarly, the best time for heating maintenance is in autumn before you start running the heater. This allows us to prep your unit and ensure that no problems will occur during operation. SuperTech Heating & AC has generous maintenance agreements for homeowners in Baltimore.

Frequently Asked Questions

Why my AC running but not cooling the house?

Nobody likes when their AC is on the fritz! Have you checked your thermostat settings? Is everything set to cool, and are your fan's settings on auto-mode? Okay, what else could it be? You might need a refrigerant leak fix, dirty coils cleaned up. Or maybe there was ice build-up in our evaporator coil or even some clogged filters. There are tons of ways we can get that air back down cold for you in no time at all with just one call over here at SuperTech HVAC Service- call or schedule online today!

How long will my central Air Conditioner last?

Ready for a new system? If your air conditioning unit is about 12-15 years old, it might be time. The lifespan greatly depends not only on the age and how you've maintained it. Also, how well they were installed can play an important part in the process too! As our AC units get older there comes a point where replacing them is more sensible than repairing one that's over 10 years old right around then. 

How Much Does It Cost To Repair An Air Conditioner?

The question is: "What does an AC repair cost?" Well, it depends on what problems you're having. Most homeowners pay between $150 and $600 for a standard repair, such as replacing capacitor--but more complicated repairs like replacing your compressor or evaporator coil can run anywhere from $1,000 to $3,500!

How Often Should My Air Conditioner Be Serviced? 

Your air conditioner is important; it helps you and your family stay cool in the summer heat. Make sure to service it before heavy usage starts, so that it can maintain peak performance! Did you know that an un-serviced system loses 5% of its efficiency every year? To help keep things running smoothly (and save a little on electricity!) change out or clean filters monthly too. Learn more about servicing your AC here!

Let's not forget about heating systems--they should be tuned up this fall for best results next winter.

How Much Does It Cost To Replace An A/C?

Getting central air installed can be a bit of an investment, but it’s worth every penny. The average cost for installing the system in your home runs about $3,700 to $8000 bucks depending on what size unit is needed, along with the types of system you choose and the condition of your existing air ducts. But don't worry if that sounds like too much money - we have affordable financing options and low monthly payment plans!

Shall I repair or replace my AC unit?

You're debating between repairing and replacing, but which should you choose? Multiply the unit's age by the cost of repairs. If the total is less than $5000, it's usually better to repair.  However, if repairs are becoming too frequent, then replacement is your best option. It might be worth looking into energy savings for a new system as well! Get in touch with our technicians today - they'll help determine what needs doing on your particular machine before giving their all-clear verdict.
