"We hired Juan to installed new subway backsplash and remove old peel & stick backsplash from kitchen. Juan mentioned he was a little busy but will be able to take the job on and complete it on a timely manner. Juan installed the backsplash on a Friday evening after 4pm and worked until about 10pm to get the backsplash completed. Juan returned on Sunday after noon to complete the tile work after allowing mortar to dry. However, the issue was Juan did not wipe up access mortal and/or cleaned off the tile. Juan left drops of mortal on our floors (which we had just cleaned from Stanley Steamer). Juan left a few pieces opened-no tile is in those cracks. Juan left the tile backsplash with streaks from the sponge. And Juan did not apply border of caulking to the edges. Juan left tile with streaks and clumps of mortal around our cabinets, on tile and on the wall. After discussing these concerns with Juan he mentioned I was criticizing his work and his integrity. Juan mentioned he has not had a dissatisfied customer who have complained about his work. I mentioned to Juan my OCD kicked in and when we hire someone to do the work the expectation is to complete the work to customers satisfaction and clean up after you have completed your task for the day! Juan mentioned he will return to ensure we are satisfied and complete the work and neither less to say I received a text from Juan stating he will return $100 off the bill that was paid to us and he does not want to work for us! Bad customer services and not acceptable for any customer Very Disappointed"

"I had to replace my old boiler heat as it was not repairable. So I purchased a NEW wall-mounted, modulating gas, condensing, combination Boiler. It replaces BOTH my boiler heater & Hot water tank. The new unit is attached up on wall with a small tank, gas, water lines below. The 2nd pic is where old hot water heater used to sit. Now I have all that extra storage space!! And no need for upkeep & repairs on a big old hot water heater!! The only thing I can complain about was that they were here for 12 hrs!! start to finish. Plus I was here sitting practically on top of a space heater dressed very warmly all day. And of course this was in January 2025 in northwest Indiana. I think this was a 1st time install for them in an older home not a new build. I would have rated them as a 5 star if not for the LONG DAY it took to be installed. They all were very nice, kind & cleaned up their mess. They brought large painter cloths to put down on floors due to going in out in the snow also."

FAQs for heating and air conditioning service projects in Merrillville, IN
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.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved 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
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
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.
