Commercial HVAC Services FAQs

Do you service commercial rooftop units?
Yes. We repair, maintain, and replace commercial rooftop units (RTUs) and light-commercial split systems for offices, retail, and similar properties across Montgomery County.
How quickly can you respond to a commercial HVAC emergency?
We prioritize commercial downtime and offer emergency and after-hours service to minimize disruption to your business and tenants. Maintenance-agreement customers get priority response, which is one of the biggest reasons property managers set one up.
What kinds of commercial properties do you serve?
We handle offices, retail spaces, restaurants, and other light-commercial buildings — anywhere with rooftop units, packaged systems, or light-commercial split systems. For very large industrial or specialized process cooling, we'll tell you honestly if a specialty contractor is the better fit.
Can you set up a maintenance agreement for our building?
Absolutely. Commercial maintenance agreements keep your equipment tuned, reduce surprise breakdowns, and include priority scheduling. Call (831) 461-3437 to discuss a plan for your property.
How fast can you respond to a commercial emergency?
We prioritize commercial downtime and offer emergency and after-hours service to minimize disruption to your business and tenants.
What does a commercial maintenance agreement include?
A typical agreement covers scheduled seasonal inspections before peak cooling and heating demand, filter changes and coil cleaning, belt and motor checks on rooftop units, electrical and refrigerant testing, and documented service records for your budgeting and warranty compliance — plus priority emergency response to keep downtime short.
Can you handle multiple units across several properties?
Yes. We work with property managers who oversee multiple buildings, coordinating scheduled maintenance and repairs across a portfolio so every space stays comfortable. A single agreement can cover several locations with consistent service records and one point of contact.
Do you provide written estimates for commercial projects?
Always. Every commercial repair or installation comes with a written scope listing the equipment, labor, permits, and any exclusions before work begins. For larger projects we coordinate Montgomery County permits and inspections and document startup results at completion.

P&Y (Pedro) and his crew were absolutely outstanding. My unit was about 20 years old and giving problems. He was very responsive and made an appointment the same day. He not only told me the issue but gave me options — a repair price and a price on a new unit — even knowing the unit was 20 years old. Other companies just told me to change the unit. His crew spent almost 7 hours and tested it so it worked perfectly. Reasonable and great pricing than these big box companies.

AC Installation

Great service and very honest. My parents had an HVAC issue where they called two different companies and both said to replace the whole unit. We decided to go for a 3rd opinion and contacted P&Y. It turned out to be a simple fix.

AC Repair

Pedro found and repaired the problem with our AC that others had missed. He was prompt, professional and very pleasant to deal with. Very important to us was that the cost was reasonable AND that he concentrated on fixing the AC instead of trying to sell us a new one. I strongly recommend him.
