"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."

"Should have made this review last year when the work was done. Doesn't really have the option to pick what I needed done. I requested my porch columns to replaced. He gave me his recommendation as to what he would do. He was extremely nice to work with. He even let me hang around to ask questions while he did the job so I could learn a little bit."

Heating and Air Conditioning questions, answered by experts

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.
