We are a father-son owned HVAC business established in 1989. Our work stands out because of a few reasons. First, our attention to detail is of uttermost importance, not only aesthetically, but our heating/cooling calculations are double and triple checked. Secondly, we listen to our customer's needs and customize solutions based upon their specs and bottom line. By far, the best part of the job is getting to know our clientele!

"very satisfied with the work. friendliness and reasonable prices. highly recommended"

For a locally owned and operated Westchester County plumber with the skill to tackle plumbing and HVAC problems big and small, Flotechs Plumbing Inc is the clear choice. We have technicians available in your area ready to bring you the service needed to get the job done right.

"I take back all the good things I said about them in 2 previous reviews! We needed a faucet replaced and I spoke with the Flotechs owner. He told me to buy a faucet on line and then schedule a service call when it arrived. The fauced arrived, and the plumber came (a few hours late). Turns out, the faucet was the wrong type. The owner didn't tell me anything about different faucet types, etc, so I purchased one from Amazon that looked similar. Turns out, it doesn't fit. The plumber came and removed the old faucet so I could take it in to a Home Depot (or similar) to get a replacement. But to install the new faucet would be another $400 (actually, 397.41) service visit charge. We've removed them from our contacts list, and will hire somebody else to install the faucet. Imagine- nearly a thousand dollars to switch out a faucet."

Heating and air conditioning services FAQs

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
