"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

We're Morris Mechanical LLC, and we've been a premier heating contractor in Easton, PA, since 2014. We specialize in heating, air conditioning, and plumbing. We offer service installation, heater replacement, mini splits, new construction, emergency repairs, and much more. We're looking forward to partnering with Northampton, Bucks, and Warren counties to continue to offer a premier HVAC experience. We'd like to personally invite you to contact us for a tune-up, today!
"I’m not sure my words can express just how grateful we are to James from Morris Mechanical. Our AC died during this last heatwave at 4 A.M. and he responded immediately. He offered to come at 8. He was punctual, polite, and knowledgeable. What we hoped would be an easy quick fix was in fact not in the cards for us. He helped us understand our options, how the A/C unit functions and although he had other calls came back the same day to install a new unit and coils. Although I’m not thrilled with having to replace these items, I am thrilled that it was James who did it. We have tried 4 different hvac companies in the 5 years we have lived in our home and we will not use anyone other than james going forward."

We are a full service Cooling, Heating & Electrical company. We employ Nate Certified Technicians, EPA CertifiedTechnicians. Our Home improvement License # is 19HC00144800. We also are a Lead Certified Contractor. Our Electrical Division License # is 11850B. Award winning.
"Ever since Bloomfield Cooling, Heating & Electric replaced a 5-year-old furnace that had been improperly installed by another contractor, we have relied on this North Jersey HVAC contractor for all our heating & cooling maintenance needs. Not only is the team responsive, polite, and professional, they have a great understanding of the latest HVAC technology and always recommend the best equipment. I recently had the company replace my downstairs HVAC system under the Carrier Cool Cash and PSEG Instant Rebates programs. The work was done efficiently, cleanly, and I am enjoying greater energy efficiency in my home. Next year I will have them replace my upstairs system under the same program. I cannot recommend Bloomfield Cooling, Heating & Electric enough."

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.
