"Local HVAC team was very responsive and recommended the right amount of work to modernize my AC system, which had suffered a leak. Other companies were suggesting either doing too little or too much (and charging a ridiculous amount). Everything worked great and the place was cleaned well."

"My electrician from Cotti-Johnson HVAC was a master electrician. If you get him, you are getting the best. I went with the most expensive work package of the 3 that were presented. First off, it was pricey. I knew that going in. I want Cotti-Johnson to understand that I am serious about a working relationship with them. I feel I have done that with their electrical department. Now, if I need their plumbing or HVAC service, our relationship can build off the first experience."

"I had a new Furnace and AC compressor system installed. All of the installers were very professional and courteous. Ryan (the owner) was great to deal with...Eric also came back and installed 2 new dampers, and was great! And dealing with Debbie in the office was a pleasure! I would highly recommend that you call them for your heating and AC needs!"

Heating and Air Conditioning questions, answered by experts

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.
