"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."

"The HVAC worker was very informative."

"I have an annual contract with R.W. Harrell's Pump Service to clean and service the heating and A/C systems at my home. Their employees and always prompt, courteous and professional and ALWAYS do an excellent job with cleaning up before they leave. Their prices are reasonable and I like dealing with locally owned companies as opposed to the nationally owned companies. I would highly recommend R.W. Harrell to all of my friends and relatives for their HVAC needs.

They were prompt, incredibly professional, and truly care about getting the job done right without overcharging.
