"From beginning to end, The Right Choice Heating and Air Conditioning Co. provided superior quality customer service and onsite work. From scheduling, to multiple follow-ups and reminders, re-confirming exact appointment time, and the post-inspection follow-up, they have truly impressed us. More importantly, Michael Taib, the technician who performed the work at our home, was indeed a true gentleman and professional. He was extremely knowledgeable and patient. I am familiar with the type of HVAC related work requirements, the lingo, and technician data. I quizzed him several times and he constantly responded with 100% honest and factual answers. He tirelessly worked on both of our HVAC units and performed the necessary services and repair. He was polite, courteous and clean. His most impressive talent was ensuring my wife's absolute confidence in his work after she grilled him with so many questions! We will continue to refer True Choice to all our friend and family! Call them; you will not be disappointed."

Trinity Heating and AC is so much more than another heating/AC company. We exceed our customer’s expectations and standards in a number of ways; such as arriving within the promised time frame or leave our work space cleaner then we found it! We provide custom solutions that take all factors into consideration so we can design a system that will meet the needs of your home and everyone in it! We offer so much more then just replacement of your existing system or installation of a new one. Do you have high utility bills when you are running the system, or someone’s allergies are aggravated when running the system? No matter what your need, if it has anything to do with HEATING, COOLING, AIR FLOW, or AIR QUALITY; TRINITY HEATING AND AC is ready to help!

"Chris was able to fix our ac unit, where my old account guy said we NEEDED to replace it!!! Plus Chris is very personable and I believe he is very honest and forthcoming as he could have sold us a new system, but found us a much cheaper option!!"

"Had them do 2 units on my property. The first one was great, the pre team is great, and the guys who actually do the work. After the 2nd one, where I chose the more expensive option to get a Mitsubishi Heat Pump, the unit would not turn the fan on some of the time. I told them, and wasted insane amounts of time. They kept saying things like 'I am trying to understand what doesn't work.' 'Pretty simple, you choose to run the fan to simply circulate the air and the icon goes, Nest thinks it is on, but does not go on.' Then they said they were going to have a Mitsubishi tech come out and for sure it would get resolved. Never happened. Just listened to a book on Benjamin Franklin and he and John Adams had to share a bed one time while traveling and Adams went to close the window and Franklin said this place will be a tomb if you do. That was what 250 years ago? and HVAC is their business? Guess I will have to take them to court. The office staff post job is a clown car of silly children. So if your job goes great, they will be a good choice. If you run into an issue you will wish you hired ANYONE else. You've been warned."

Heating and Air Conditioning questions, answered by experts

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

Replacing an evaporator coil costs around $1,350 on average. The coil itself, depending on the size and brand, can cost from $550 to $1,100. Professional labor averages about $700 total. Note that a license is required to work with refrigerants, so it’s necessary to have an AC pro complete this task.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.
