"First, my project was to install, from scratch, a new HVAC system, including ducting, with tha furnace in basement (initially, it was upstears in a closed). Last year and early this year, I got 3 contractors on site, by direct call, and none of them answered my spefic questions but taking pictures and promising that will send an estimate. I never got it. I was getting anxious. So I got the idea go to Angi. First visit I got in the same day I put my request on Angie's site, called his boss advice me to just change the furnace. I could not, because the previous system was heating OK only one half of the house. Finally, next day I got AJB visit an made me happy. He understood perfectly what I wanted and my concerns and explained to better and quite ingenious solutions on my suggestions. I understood him perfectly because I have strong knowledge of aero-dinamicsor or fluid mechanics so I signed the contract right then. Now, I have a sweet warm house in every corner of it."

"If I could give them 0 stars I would, I was googling products to unclog my kitchen sink when I saw an ad for $49 to unclog drain in Eldersburg, I was in Eldersburg at the time. I called to make an appointment, when I gave the young lady my address, she said I don’t see the special in your area, but I’ll honor the coupon. I asked if there were any hidden fees? she said NO, I said unclog for $49 that’s great! She nor the ad indicated the $49 was just a diagnostic fee. The plumber came out and says that’ll be $412. My kitchen is being renovated so there is no sink, just the pipe for the snake. I called Tristate and spoke to Diane who listened to my rant and was very apologetic. Extremely over priced!!"

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.
