"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."

Choosing the right Heating and Air Conditioning Contractor is very important. Chances are you are going to make a substantial investment in your new HVAC system with which ever contractor you choose. There is nothing worse than investing a large amount of your hard earned money in a new system and winding up with a system that is noisy, inefficient, and does not perform properly. Or even worse, one that fails prematurely. Surprisingly enough most HVAC Contractors have no formal training. Untrained HVAC Contractors frequently do not size systems properly which could result in improper cooling, very high utility bills, and even systems that fail prematurely. Before you even consider a contractor make sure they are NATE Certified and Air Balance Certified. North American Technician Excellence is the Prestigious Certification of HVAC Competence. Using a NATE certified contractor is like using a surgeon that graduated Harvard Medical School with honors. Air Balance Certified contractors understand airflow which equates to efficiency and comfort in your home. To have a system designed properly a contractor has to understand air flow. At Southland we offer this high level of expertise. Yes, we are very good at what we do and there is no question about that. Our reviews and ratings prove that. Our installations are unparalleled with every system being designed specifically to the home. All options for a quality installation are included in every system we install. From basic systems, high efficiency systems, to specialized zoning we do it all. If you are searching for a knowledgeable contractor you have found one here. We offer extremely competitive pricing and expert design knowledge.

"Dave was very efficient and knowledgeable. He was able to supply my quote before he left. I look forward to working with Southland heating and air. Follow up: I made my decision and signed the contract. Best decision I could have made. They were thousands of dollars less for the exact same equipment than 3 other companies I got estimates from. When challenged none of the other companies could revise their estimate to even come close. Southland is a Mitsubishi diamond dealer so I got full Mitsubishi warranties plus 1 year from Southland of parts and service. The day the installers arrived, on time, it was raining. Jamie and Ricardo used the utmost care to protect my home. They covered the floors, moved and covered the furniture and made sure before they left that I fully understood how to use the remote and operate the equipment. I have attached a photo so you can see for yourself the way they carted for my home. The equipment works perfectly. I would hire this company again in a heart"

"He showed up to assess the job. We agreed on a price. He told me he was busy for a month so I waited. The day before the job he messaged me to send him more than half up front or he wasn?t coming. He never mentioned advanced payment. I said I wasn?t comfortable but would certainly pay him as agreed for the job. He told me he wasn?t coming if I didn?t send him money first. For a handyman? Leave me waiting for a month then demand payment up front before doing one minute of work? Totally unprofessional!!! Time waster!"

Heating Oil questions, answered by experts

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.
