"On estimate
Rich was prompt, friendly and professional. He was straight with me and honest. 

Another HVAC company told me I had to install pumps to each unit (I have 3) to help the flow of water (a total of $600). Rich explained to me that all that was needed were some "T" pvc for venting ($0.39 each) that he had on hand. Since it was a quick task, he put them in for free.

He gave me a price that was $1,200 LESS than another estimate.

On the work
He called the day before letting me know the weather looked bad on the day of the install - depending on the weather, he might have to do it the following day. I really appreciated that notice given I have tenants. It was very professional.

When the weather was better, he showed up- as promised - and he kept in communication with me.

A few hours after he left it wasn't cooling the apt. We chatted by text even though it was late. He came out the next day without complaint and fixed the problem. All the while keeping me informed.

Overall
Although the install was a bit bumpy, he never complained, was considerate, easy to work with and treated me very well.

He has earned a customer for life.

Heating and Air Conditioning FAQs, answered by experts

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

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.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.
