CHAC can perform maintenance service on an “as required” basis on all brands of heating and A/C equipment. A detailed written report, sent via e-mail, of any problems found while performing our maintenance service will be provided, along with itemized pricing for the recommended repairs. Should you move forward with our recommended repairs, no “Trip charge” will be assessed on the return visit.

Additionally we offer a range of Maintenance service contracts, structured to fit your needs and budget, all but eliminating costly emergency repairs. See our Contract Service page for more details.


Unforeseen breakdowns are a nuisance, and an inconvenience to your tenants, CHAC gets you back up and running quickly with our 24/7 service and highly trained technicians. We diagnosis the problem correctly the first time, and if we cannot repair it on the spot, we can usually have the needed parts in hand the next day, to minimize your down time.


If your system is older and repairs are getting expensive, or the system is not energy efficient, we can provide an estimate for replacing it. We also provide a corresponding repair cost so you can make an informed decision. We can often get the system replaced in one business day saving you time, money and the inconvenience of a prolonged shut down.


New installations, unit replacements, and tenant improvements are a core competency of CHAC. We offer rapid turn around time for package type replacements to minimize discomfort. Over 90% of the time we will have your old unit removed and your new unit installed and operational, the same day. CHAC will coordinate all details of the project; including, roofing, electrical, ductwork, piping, structural, all permits and title 24 reports.
