"Really fast and professional service when our HVAC broke in the peak of summer. Had it up and running in almost no time. My advice to first time homeowners like me in these cases is to always make sure you know what repairs and actions are being done. It'll help in regards to money."

"Everything went great. The old hot water heater was removed and then the new hot water heater was installed where I requested it to be with all of the plumbing done in a neat professional manner. It was a pleasure working with Bamford plumbing and I have been very happy with the work they have done. I would highly recommend them to anyone.

"Victory HVAC installed 2 mini splits for me. Great communication, they showed up when they said they would, the job was completed in one day. They worked with me regarding placement as well as advice what brand to buy. Excellent service, reasonable price, they cleaned up when done and were very easy to work with. Yossi is extremely knowledgeable about all things HVAC. Super nice guy to boot. I will definitely use Victory HVAC for all my HVAC needs in the future. 5+ stars"

"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."

"I had done my research on the ductless AC that I desperately needed for our 3rd floor master bedroom. I recieved several estimates from several companies. This company's sales rep did an honest assessment at a great price. This AC unit is really life changing. I would highly recommend them."

"Overall it was great. The plumber answered questions and was timely. I discovered a small leak at a soldered fitting after he left and he came back the next morning on a Saturday to correct. I recommend Pohlman for large or small jobs."

"We came in to work one day, to find there was no AC in our offices. It was 90+ degrees that day, and as owner of the company, I saw that there was going to be little to no productivity that day. I called several companies, only to be told it would be a day or two before they could service our system. I was on the verge of sending everyone home, because the fans I purchased, just weren't doing the trick. Then, I called Paramount. Alan was at our offices within the hour. He determined it was a fan motor, and after a short trip to his office, had the new fan in hand. He also recommended replacement of a capacitor that he deemed to be on it's last leg. I figured he'd have to run to his shop again to get that, but he showed me a Full Stock of parts he had in his van. I'm in the Service Industry, and I have to admit I was impressed how stocked and organized his truck was. I was expecting a high bill, due to the response time and having to run back to his shop for fan. I was somewhat shocked how reasonable the bill was, and even added a little extra! Alan stayed around for a short time afterwards, and gave me some tips on what to do to keep my AC unit running efficiently. We have recommended Paramount to several companies and friends since this time, and they all have been pleased. We found our permanent Heating and Air company, and highly recommend Paramount to all. Thanks Again Paramount, and especially Alan, for doing a Great and Professional job! Russell with DTS Communications in Nottingham"

Heating and Air Conditioning questions, answered by experts

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs.
