AC Installation, AC Repair & HVAC Services in Delhi NCR and India
AC इंस्टॉलेशन और सर्विस
Split, ducted, cassette and VRF systems, ventilation and servicing — planned and installed by verified HVAC teams.
Cooling and ventilation, sized correctly
HVAC stands for heating, ventilation and air conditioning. In Indian homes and businesses it mainly means installing and maintaining air conditioners — split, cassette, ducted and VRF systems — along with exhaust and fresh-air ventilation. Correct sizing, neat copper piping, proper drainage and good electrical supply decide how efficiently and quietly a system runs.
Homeowners need HVAC contractors when installing ACs in a new or renovated home, when planning concealed piping before a false ceiling, when switching from window units to a ducted or multi-split system, or when existing units cool poorly or leak water. Offices, shops and clinics need ventilation and cooling planned for occupancy and equipment heat.
Planning is easiest during construction or renovation, when pipe routes, drain lines, outdoor unit locations and power points can be built in.

HVAC & AC — frequently asked questions
How do I choose the right AC capacity?
Capacity depends on room size, ceiling height, sun exposure, occupancy and appliances. An HVAC contractor can estimate the heat load and recommend capacity.
Should AC piping be concealed before interiors?
If you want a clean look, yes. Concealed piping and drain lines are much easier to install before false ceilings, wall finishes and furniture.
What is a VRF system?
VRF (variable refrigerant flow) connects several indoor units to one or more outdoor units, adjusting refrigerant flow to each room. It suits larger homes and offices.
Why does my AC leak water indoors?
Common causes are blocked or poorly sloped drain lines, a dirty filter or incorrect installation. A technician can diagnose and fix it.
Is it free to get AC installation quotes on SiddhiSadan?
Yes. Posting your requirement and receiving quotes is free, without obligation.
Why is my AC not cooling and who can fix it near me?
Common causes are dirty filters, low refrigerant, a faulty capacitor or blocked outdoor unit. Share your locality and AC type; a verified technician will inspect and quote before any repair.
What is the charge for AC installation?
It depends on AC type, pipe length, stand or bracket, wall drilling and electrical work. We do not list fixed rates; ask for a written quote including extra pipe.
AC ठंडा नहीं कर रहा, मैकेनिक कैसे बुलाएं?
फ़ॉर्म भरें या कॉल/व्हाट्सऐप करें और AC का प्रकार व इलाका बताएं। सत्यापित टेक्नीशियन जाँच के बाद कोटेशन देंगे।
क्या AC में गैस हर साल भरवानी पड़ती है?
नहीं, सामान्यतः गैस तभी कम होती है जब कहीं लीकेज हो। पहले लीकेज की जाँच करवाएं।
