On the Spot HVAC is a great company you can trust. Patrick McGraw has been wonderful to help me with my aging system. I had to replace the system but they were very upfront regarding pricing. Plus, their warranty and service agreement makes it a great deal. You can count on this company for your HVAC needs. I wouldn't use anyone else for HVAC needs.
I cannot say enough good things about Aaron and the team at On the Spot HVAC. After weeks of dealing with burning eyes and throat irritation every time my heater ran, they came out and took my concerns seriously from the very start. They replaced the entire air handler in the attic, the outdoor unit, cleaned the ducts, and even cleaned my home afterwards. The whole job was done professionally and efficiently between 8:30 am and noon. Aaron was knowledgeable, honest, and made my health concerns a top priority instead of brushing them off. The difference is night and day. The air in my house finally feels clean and safe again. If you are dealing with HVAC issues and want a company that actually listens and does the job right, On the Spot HVAC is the one to call. Highly recommended.
We had a great experience with On The Spot HVAC. From the first call to the final fix, everything was handled quickly and professionally. They showed up on time, explained exactly what was going on with our system in a way that actually made sense, and didn’t try to upsell us on things we didn’t need. The technician was knowledgeable, respectful of our home, and efficient. You could tell they genuinely care about doing the job right, not just getting in and out. Pricing was fair and transparent, which is always appreciated. If you want honest, reliable HVAC service without the stress, I would absolutely recommend On The Spot HVAC. We’ll definitely be using them again.
Aaron G and his crew were very professional and did a great job installing our new air handler. They made sure our floors were well protected before installing and clean after they were done. Aaron took the time to go over everything once it was installed. Cody at the office was also very helpful and willing to work with us on the cost and coverage. We highly recommend On The Spot.
I've been using On the Spot to perform bi-annual inspections for the Summer/Winter seasons and they've been great. It's a relief to know you're system is maintained and working as it should. Also, any issues I've had they would come out right away and for free. Today, Jeffrey came by to do our winter inspection. He arrived on time and gave me updates and recommendations. Always a pleasure to work with them! Thanks again.
