"SCORE If I could give this family company 6 STARS I would. HVAC PROBLEM IHVAC system would not turn on. PROFESSIONALISM 10/10 - Andy has a friendly and professional attitude to his work. Very knowledgeable answering all my questions and making suggestions on how best to preserve my HVAC system. PRICE Very reasonable and fair. TRUST Trust is always a thing with me. I have encountered people in the past that have scammed me for money making a small job into a mountain just for the extra money. Andy is not like that at all. He showed me where the problem was on my HVAC which turned out to be an easy fix but could have easily scammed me had he been a different person. - it shows this man to has INTEGRITY. WILL I USE HIM AGAIN? Absolutely yes. I now keep his business card in a safe place. Andy is now my go-to man for any HVAC service."

"Chose Brothers via Angi to determine our heat pump problem. Their assessment led us (given it's age) to decide to replace the system. I obtained multiple quotes and Brothers was priced the best. They promptly installed a new system. All of the guys involved like Matt, Andrew, Shawn & Jamal (forgetting the electrician and another tech guys name, but they all) did an excellent job. I would highly recommend using Brothers for your HVAC needs."

Heating and Air Conditioning FAQs, answered by experts

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
