"So happy I worked with Magna for my issue! They came within 45 minutes of me posting on Angie's List... that has to be some kind of record. They diagnosed the issue quickly, clearly communicated what was needed and what the cost would be, and I moved forward with it. My AC was back up and running within an hour. Highly recommend! I've saved Magna Tech's phone number in my contacts and they will be the first company I call every time I have an HVAC issue."

"I contacted Sean to repair my aging HVAC system. Although I have very little knowledge of HVAC, Sean was able to identify, explain, and plan the maintenance of my current system in language I understood and that seemed reasonable. Sean was very responsive via text during our scheduling and I'm happy with the expert level of detail he showed during inspection. I would highly recommend working with him or his team. Update: Sean came back out to resolve my filtration issues and also fixed some other problems that he noticed in the process without increasing the negotiated price. Again, Iâ m extremely satisfied with the work heâ s done and would recommend him for your HVAC needs."

"Excellent service from Hecomo. Technician did not try to push purchase of a new HVAC system even though there were major issues with our system, feel comfortable while talking with an advisor. Very knowledgeable, patiently, friendly and nice person, answer all my questions. Later on, we decided to replace the whole new system with fair price and wasn’t ripped off as others. Very professional and well trained technician. I will definitely use them again."

"We got five different work proposals for our HVAC replacement. The person who came to our house was very technically knowledgable. He gave us his cell phone number and gave us plenty of his time answering our questions. I think this contractor would have done an excellent job at a good price."

"Carroll Mechanical delivered a 10/10 experience, from start to finish. From the first call, the Carroll Mechanical team demonstrated that they were knowledgable, ethical, and customer-first. First, they offered to help me troubleshoot, and they gave me some great tips that allowed me to try and fix the problem myself before they made a service call. As a not-so-handy guy, I realized that I needed the pros, so I requested on-site help. They immediately offered to come over on the day and time most convenient for me, and they spent time with me walking through the pros/cons of different HVAC options. Ultimately, the team explained the pros/cons of different remediation options, offered me an extremely competitive quote, and was transparent all along the way. I moved forward with a system replacement, which they were able to accommodate the same week(!!). The Carroll Mechanical team was timely, detail-oriented, and respectful of my home, and the HVAC system was installed as expected."

Heating and Air Conditioning questions, answered by experts

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.
