"I am genuinely flabbergasted that this company has so many five star reviews. From the marketing practices to their customer service, my frustration with them was pervasive. The work they did seemed to be fine enough, but it was overpriced (I later discovered) and their communication at several stages was just abysmal. My attempts to have them remedy the shortcomings of their process gained no satisfaction. It also left a really, really bad taste to discover that their signs plastered all over the furnaces and water heaters in the basement of our condo building was not because they had some kind of relationship with the condo *and in most cases had no relationship with the equipment that their signs were on*. Just obnoxious. To top it all off, someone my email address was leaked from their organization which led to it being the target of hacking. How would I know it was them? They were the only company that I had given that particular email address to, Then they had the nerve to ask for a customer testimonial video. As if. Would not do business with them again."

"I would thank them for the work and services. Max was very prompt and polite. We were definitely taken aback with the bill. We were not informed about any of the charges around: 1. Time taken for pulling the permit(1hour@$180) 2. Time for inspector coming in(1hour@$180) 3. Price for permit These 3 costs total to $425. The material cost of $263 definitely seemed marked up. * I wish they had mentioned about expecting these costs so that we could make an informed decision. * We have had several permits pulled in last year ( had frozen pipe burst situation so had renovations going on for multiple months) and never were charged for the time taken to pull permit or for inspectors time at the time of inspection. * Max mentioned it was going to be $180 an hour and you were here for 2 hours from start to end.. The father(Peter) kept mentioning about the emergency charges that there are plumbers that charge $300 an hour, I was clear that we were okay with waiting for a couple of days so there was no question of those charges being applied. He kept giving an explanation of the bill being high enough but it seemed very vague. We were charge $1100 for 2 hours of work to fix a slow gas leak that National grid had identified and pointed to us so they shut of our gas supply. National grid guys had told us that it would be only 1-2 hours of plumbing work. I would not recommend them for sure for the sour taste it has left for us. I wish we went with presidential plumbing or 128 plumbing that we have gone in the past. They are expensive but you know the quote before hand."

Heating and air conditioning services FAQs
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.
