"We had a phone call and he actually helped me figure out that I might need a plumber instead of HVAC repair. Mark was very courteous and so helpful! If we do end up needing to go back to him I will definitely call for them to make a visit."

"Thank you Wise Aire for giving us a great heat repair experience! After submitting a request for boiler/heat repair, Keith called me and was very pleasant. He sent Josh their technician who was just as pleasant, knowledgeable, and addressed all of our questions. Josh did a great job, he resolved our issue efficiently and at a reasonable rate. We would recommend Wise Aire, from this first experience we find them to be honest, reliable, and they do good workð"

Heating and Air Conditioning FAQs, answered by experts

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.

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. 

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
