"Mike and his team did a great job with installation of a complete new HVAC system involving a ducted system on the 1st floor and mini splits on the 2nd floor (this set up best accommodated our house for function and zoning). Their experience and knowledge was demonstrated by their well planned work and installation, including working around existing conditions such as tight crawl spaces, as well as coordination with existing plumbing, electrical, structural components, etc. They coordinated and were accommodating of requests for equipment and vent locations. And they started and completed the work as promised. I would highly recommend them."

"This job actually went from a mini-split AC quote, to a entire central AC/Heat pump and new duct-work installation, so this review is of the later. Where to start? I can't speak highly enough about Ronnie and his crew. From the lightning fast responses to my questions/concerns, the friendliness of his crew, their attention to detail, and of course, the above-and-beyond effort in making the final system absolutely perfect. As someone who has dealt with many houses from MD to FL in the past 25 years, all with existing AC units in varying states of disrepair; I wasn't entirely sure what to expect when doing a completely new installation in a home that didn't have existing ductwork, electrical wiring and plumbing. Ronnie explained to me in detail why a mini-split system wasn't the best option given my home's layout. He then proceeded to explain to me the technical and practical reasons behind his choices for the location of a central A/C & condenser, the drain routing, new electrical wiring and fuse-panel considerations, and the ductwork routing/sizing. Given all this, I was confident that things would be installed correctly from the start and I wouldn't be dealing with nuisance issues in the future. Note: That aside from the appearance and location of the ceiling vents themselves, I wasn't terribly concerned about the aesthetic aspects of this job because the majority of work was being performed in a largely unused attic space. Needless to say, I was truly shocked by the final installation. As someone who has a degree in mechanical engineering, I was impressed by the uniformity of the step-down/sizing of the duct system to deliver air efficiently to the most distant parts of the house, specifically to the two areas of the home I deemed most important, and the orderliness of the hanging flexible duct hoses. So not only did he install an incredibly quiet, efficient system, he did so in a manner that still left me with about 85% of usable attic-space by strategically locating and routing all parts of the system. To sum things up, the effort that Eastern Shore Maint LLC put into this installation (which only took two-and-a-half business days) was herculean to say the least. They had to procure the services of an electrician to drastically alter the power supply in my home, work around material shortage issues, and still got the job done a day ahead of schedule. Finally - although Eastern Shore Maint LLC wasn't the cheapest bid I received for this project, I am glad I chose them because I couldn't be more happy with and confident in the final product. From start to finish, a completely professional job!"

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.
