"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."

"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 questions, answered by experts

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.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
