5.0-Star Customer Reviews & Real Repair Stories
See why homeowners across North Dallas, Frisco, Little Elm, Plano, McKinney, and East Texas rate SunDollar A/C & Heat 5.0 stars for honest, repair-first HVAC service.
Real Second-Opinion Case Studies Across DFW & East Texas
Here is what happens when a non-commissioned SunDollar technician inspects a system after a commission-driven company pushes a full replacement:
A Frisco homeowner was told their 6-year-old 4-ton compressor had 'locked up' and needed a full system swap. Our technician tested the compressor windings with a megohmmeter — the windings were completely healthy. A new capacitor and contactor restored ice-cold air in 35 minutes.
During a January freeze, a national franchise red-tagged a Plano homeowner's furnace claiming the heat exchanger was unsafe. Our combustion analyzer and borescope camera proved the heat exchanger was 100% intact. We fixed the ignition circuit the same afternoon.
Cottonwood and grass clippings had matted between the split condenser coil fins, causing the compressor to trip on high head pressure every afternoon. After a deep coil flush, amperage dropped 35% and the unit cooled effortlessly.
When replacement truly WAS the right call on an 18-year-old R-22 system, the homeowner used our online bundle pricing instead of paying a commission-inflated quote — saving over $7,300 for the exact same tonnage and warranty coverage.
What Our Customers Say
Saved us from an unnecessary $11,000 replacement!
“Another company told us our compressor was dead and quoted $11,500 for a whole new system. SunDollar came out for a $0 free second opinion, found a failed capacitor and burnt wire, and had our AC blowing ice cold in 40 minutes. Honest technicians like this are rare.”
Upfront prices online and zero sales pressure
“Refreshing to work with an HVAC company that actually publishes their prices online and doesn't charge a trip fee just to walk through the door. Fast same-day dispatch, spotless work, and super respectful technician.”
The $19.85/mo plan covers BOTH of our AC units!
“We signed up for the $19.85/month Access Comfort Care Agreement because our two-story home has two HVAC units and every other company wanted $40–$50/month for two systems. They tuned up both units thoroughly, washed the coils, and never tried to upsell us.”
Same-day emergency repair on a 103°F Saturday
“Our AC went out on a 103-degree afternoon. SunDollar answered the phone immediately, dispatched a tech the same day with no trip fee, and cleared our clogged drain safety switch and replaced a weak contactor. 5 stars all the way.”
Installed our new system for thousands less than 3 other quotes
“We got three quotes ranging from $13,500 to $17,000 for a 4-ton system. SunDollar's online bundle price was thousands less, included a new thermostat, float switch, and 10-year warranty, and the install crew left our attic cleaner than they found it.”
Dependable rooftop unit & indoor air quality service
“SunDollar maintains our commercial RTUs and installed CASPR air purification in our facility. They show up on time, communicate clearly with photos, and keep our equipment running reliably year-round.”
