Four Seasons Heating and Cooling botched the installation of my thermostat. When I reported the issue, they only had time for the next day's appointment - unacceptable. Given it was freezing outside and about to get even colder inside, I urgently needed help. Thankfully, A&J Heating arrived promptly within an hour, swiftly fixing the problem that Four Seasons had created. I'll definitely choose them over Four Seasons from now on for any HVAC needs.

We had a faulty water heater that needed replacing. A&J offered a fair quote for the job, installation, and removal of the old unit. The service was done efficiently and professionally. They provided helpful info about our new heater and were easy to deal with throughout. Good experience overall.

Ulysses and his team delivered a top-notch service. Extremely friendly, knowledgeable, and professional from start to finish, they exceeded my expectations. I'll be recommending them to everyone I know.

A&J is top-notch - Mr. Trejo is extremely knowledgeable, breaks down complex issues in simple terms, and does exactly what he says. I recently purchased a home that had an antiquated heating system and no central air, but A&J swiftly replaced the old unit with a new one. We're thoroughly satisfied with their work, and they landed on a fair price point.

The technician was transparent about the work needed, without trying to upsell extra services. They offered a competitive price for Freon, especially considering they don't charge for diagnostics when completed on the same day. The air conditioning is now working properly, and I didn't experience any additional stress from being sold unnecessary extras or pressure to schedule further maintenance. I'm satisfied with the service provided and the overall outcome.

It's been a week and I've heard nothing from them. I get that they're busy, but not following up on a voicemail about a non-existent heat issue is unprofessional. The "as soon as possible" promise isn't worth anything if you don't deliver.

I stumbled upon this company through Groupon. They showed up on time, the technician knew his stuff, and got it done fast. I also opted for an ecobee thermostat installation for extra cash. He took the time to explain everything and was super patient. Will definitely be back for my furnace and AC maintenance - no hesitation!

I would wholeheartedly recommend this company to anyone needing service - you won't be disappointed by calling them.

This company is trustworthy. When I lost heat for a week after three other repair attempts, A&J arrived promptly and resolved the issue on the spot.
