Highly Recommend!
Donovan answered immediately after hours and showed up 20 minutes later at 9 pm and solved the AC issue. Very responsive, honest, and respectful of my home.

Excellent Job!
Donovan with DAP installed a minisplit system for my garage. He did an excellent job. Showed up on time and knocked it out. I live downtown so he tunneled under the concrete to get the look i wanted to achieve. DAP also has came and fixed my 6 ac units on multiple occasions on my previous house. Always a great experience. He is honest and fair. I highly recommend his service, you will not regret it

Quick and Efficient!
This was my first time calling DAP for my AC needs and I will definitely call again! Donovan came out late Friday evening and was back bright and early Saturday morning to get the work done! Quick and efficient!

DAP installed a new thermostat that automatically changes over from heat to a/c and back at a better location in the house to balance the temp. Also, added a register to another room that is always hot.

Prompt and Professional!
My A/C system in my home has not cooled properly in 2-1/2 years, and Donovan was able to get everything running right in less than an hour. He was very prompt and professional, with very fair pricing. I will definitely call DAP for all of my future HVAC needs.

Very Professional!
Donovan was 100% professional and very through. He had my old unit running like new in no time at all. Definitely will continue with his services and will purchase a maintenance plan with him.

Veteran Discount!
I received several recommendations to call Donovan Preston to service my A/C and figure out why it was sucking so much electricity. I’m glad I did. He was polite, punctuated and respectful of my property. He was very thorough in figuring out the problem. He patiently explained to this first time homeowner all about A/C maintenance. He set me up on a bi-yearly maintenance schedule that (not only cheaper than his competitors) but it also fit my budget. The Veteran discount helped too. I think that word of mouth is the best business and I hope this review helps grow his business.

100% Recommend!
I can totally recommend hiring DAP!! Donovan was very thorough in repairing our furnace and was able to get us running during the arctic freeze a couple of weeks ago. Very satisfied with his work and appreciated how speedy he was to get to us. Bravo, Donovan!!

Awesome Job!
My elderly parents heat went out during an ice storm. The first company I called canceled on me. Second didn't have the part. I should have just called DAP first! Came out at 7 pm at night, had the part and was able to fix my parent's heater the first time. This will be the only company I call from now on! Great customer service and honest and fair pricing! Definitely give them a call!

Knowledgable and Quick!
Donavan was very knowledgeable and quick! Came out right away at 7pm. He knew within 5 minutes what was wrong with our carrier infinity AC. Ordered the part on Wednesday. Fixed it on Thursday. We highly recommend him. Great service give him a call for your repairs.
