"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."

"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.

Heating and Air Conditioning questions, answered by experts

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.
