The Air Is Too Hot

Sometimes, your air conditioning system is pumping out air, but it’s hot air, making your house even more humid and warm. To fix this issue, we look for obstacles in your vents, such as hair or rodents, and ensure that your filters are clear. We also check if your refrigerant levels are low.

The System Doesn’t Work

If your central air should be running but you can’t turn it on, we inspect your electrical system to see if your pressure switches and breakers are running correctly. We also look at your AC unit’s start capacitor and compressor to figure out if they’re overheated or broken. Finally, we check your thermostat’s settings; if it’s broken or you’ve chosen a higher temperature, the AC won’t turn on.

The System Makes Noises

AC units don’t make much noise when they’re running properly, and if you hear rattling, buzzing, or thudding noises, it’s time for air conditioning repairs. Unusual noises indicate a variety of problems:

  • Failed capacitators

New companies and contractors are often good at what they do, but they present more of a risk because they don’t have years of experience and referrals to back them up. Particularly if your heating and cooling system are old, it’s safer to choose an established company.


Hearing exactly what a company is going to do to your HVAC system is critical when you need air conditioning repair. A good HVAC contractor keeps you updated on his or her findings and lets you know before completing a service that comes with an up-charge.

Diverse Services

Most HVAC services are related to each other. Getting your AC inspected before the spring weather gets too warm is important, but so is having your furnace checked before the fall turns blustery. Sometimes, your AC is too broken to be replaced, so you need to find and install a replacement. Instead of choosing a separate contractor for all these HVAC services, find one that is licensed to perform all of them.
