"Very courteous and prompt. Explained everything as well as showed me the issue. Ended up having to have a new home heater. Helped to get a decent discount. Installed the new system the very next evening, fairly late 5:30-8:30 pm. The service call on the first of the new year was then returned to me. The service tech that came out, I am very impressed with. The care and service they give is absolutely outstanding. He did say he did not put my filter back in and I would need to purchase a filter in the next couple of days. He also explained the gimmick about the costly filters, which I never knew. The payments posted my accounts the very next morning. I would definitely recommend this company! I didn’t feel blindsided or taken advantage of, being a single female this is a huge plus! "

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.  

If your AC refrigerant is low, you may notice that the unit takes longer than usual to cool your home or that your energy bills are higher. You may even feel a warm breeze coming from the vents when the AC refrigerant is low. Don’t attempt to check refrigerant levels yourself. Only certified AC repair pros should check and refill refrigerant.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.
