"Very pleased with the finished work. Donny did a great job with everything, he really knows what he is doing. Put a new service entrance in, new breaker box in the basement, fixed up an old dryer plug and some new wiring. I have a few other smaller projects and he will be my go to guy. Thanks again Donny."

I have 8+ years experience in the heating and air conditioning field. I’m very mechanically inclined, therefore I’m quite useful to do just about anything. I’ve done everything from general around the house stuff to full scale renovation work. I would be my pleasure to do any work for you!

Heating and Air Conditioning FAQs, answered by experts

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

Yes, through thorough cleaning and inspection, optimizing functionality, and reducing energy use.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
