"We hired Bactronix to clean the HVAC ducts in our house. Technicians Masson and Shawn arrived on time, did their work unobstrusively and efficiently, and answered all my questions politely and fully. They sent over before and after pictures of the ductwork by e-mail afterwards. Their work has made a positive difference to the air quality in the house, and we appreciate their services."

"Our air conditioner broke on labor day week-end. Called contractor late Sunday afternoon and got his answering service.  Contractor called back within the hour and set an appointment for the following morning.  Contractor called 1/2 hour before showing up on Labor Day.  He quickly diagnosed the problem and replaced the capacitor.  This capacitor has gone bad in the past and other contractors have charged $175 - $200 to replace this part during normal working  hours. I was charged the $40 advertised service call price and $75 for the repair part. In addition to repairing the unit he cleaned it. Very professional and courteous, I would highly recommend using this company. 
Most of my dealings with HVAC contractors over the past 30 years have been mostly less than pleasant, this was quite a surprise to find an honest, hard working contractor."

"Along with installing new bedroom and closet doors, the contractor also installed vinyl plank flooring in our living room, dining room, and bedrooms. He also hung our dining room chandelier, and installed moon lights above our fireplace. His attention to detail in his work was impeccable and he completes the job in a timely manner. I would recommend his services to anyone looking to have work done on their home."

Heating and Air Conditioning FAQs, answered by experts

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.
