"Kevin arrived today for the Spring Preventive Maintenance service on our HVAC system that we purchased a few years ago from Holtzople Heating & Air Conditioning. As always, we received an email and a phone call to let us know when the HVAC technician would be arriving. The Holtzople HVAC technicians are always very professional, clean, thorough, and polite and friendly. They are always willing to answer any questions we have, and their expertise and experience are evident in the excellent service they provide."

"Our AC unit began leaking water and marginally working late on a summer Friday night, and then completely broke down over a sweltering weekend. We called McCrea's emergency line first thing in the morning because of our two young children. McCrea sent a technician to our home over the weekend in a matter of a few short hours. Mark was very professional, arrived on time, and repaired our system quickly. He expressed concern that the issues may continue in the medium term, and noted we may need to consider replacing our system. Mark offered to call his supervisor, who might be available to come over the same day (again, over the weekend!) to conduct a technical evaluation, and let us know our options. We jumped on the opportunity. Brooks arrived shortly on the same day, spent a good deal of time taking measurements and assessing our current unit and usage, and developed three replacement options (at different pricing levels) tailored for our home. He sat down and explained each replacement option, the rationale for each, and the pricing. We asked a lot of questions, which he patiently answered. We decided to replace our struggling system within a few weeks. Brooks remained engaged and responsive to our questions in the interim, and a McCrea team, led by Logan arrived on the appointed day to replace the entire system. The team was professional, courteous, and efficient, replacing the system in a few short hours, and kept us apprised of developments. When the installation was done, Logan walked us through each system, their respective manuals and documentation, and our new touchscreen user interface for the entire HVAC. Our family has had the new HVAC system for a few weeks now, and it functions beautifully. Our home's temperature and humidity is much more comfortable, and the system is quieter, easier to use, and less expensive to operate. We have had a service contract with McCrea for about eight years--since our last home--and will continue to have one with them. They are super reliable and professional. Highly recommended."

"They were prompt and very professional. They kept us informed during the entire process of cleaning our ducts and dryer vent. They also installed an air scrubber and the total cost was several hundred dollars less than the quote we received from an HVAC company. The HVAC company told us we needed mold remediationâ ¦. DuctGurus found no mold. We received great service so we will be using and recommending this company in the future."

"Not only did they replace my old oil system with a heat pump, they replaced my entire AC system as well. Much more efficient, included new thermostats which are operated via mobile devices, and gave me peace of mind. Recommended an appropriate heating and AC system, replaced everything and did it in an efficient manner. Much more reasonably priced than all other quotes, prompt service & quick completion of the task. Didn't try to talk over my head about things that I wouldn't understand, explained it clearly and effectively. Highly recommend to anyone needing any type of heating or cooling repairs or replacements."

Heating and Air Conditioning FAQs, answered by experts

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.
