"Bradley was professional, articulate, and very patient as we discussed possibilities and worked out how to move forward with repairs for water damage and final install. A great experience- we learned about options as opposed to being sales-pitched the easy sell. We wish we could hire them for all our plumbing needs, but they only do water heaters. Our new set-up is working great, and is to code. Bradley accomodated our busy schedule- much appreciated!"

"Repair was done on my daughter's car who is in college in California, I live in Colorado. The owner spoke with me on the phone prior to doing the repair to explain issues with car. His assessment was consistent with the problems my daughter described to me. The price was very reasonable for all the parts and labor. The job was completed quickly and they stayed past closing until my daughter could get there to pick up car. They accepted my payment over the phone and offered to check her fluids and inspect car periodically in the future for free. I think you will be very satisfied using this garage as this and other reviews have clearly shown.

"The representative from Baltica arrived on time. Quickly diagnosed the problem (where previous plumbers could not), fixed the water pressure valve, advised me on do's and don't in use of the Noritz system. He also advised me that I should change the cap on the water heater, which was confirmed by the Noritz representative when I called the company. I would recommend Baltica any day to any one. Knowledgeable and courteous technicians. Reasonable prices. If you have tank-less water heater, don't use just any plumber, use Noritz certified technician. My heaters were previously incorrectly installed by licensed plumber, but he did not have experience with tankless."

"My husband and I were very disappointed with the work a former company had done installing new duct work and removal of asbestos in our attic. After this job cost us a lot of money the air flow from the vents was terrible. By the time we realized how bad the problem was when the weather became unbearably hot, the company said it was past the 90 days and would not fix the problem without costing us more money. We were weary about calling out another company for fear of having the same problems. We saw an add on a little sticker that came with our paper and decided to call to have a tune-up since it had been over a year since the last disaster. We called Home Comfort and had the maintenance and a new air scrubber installed to help purify the air in our home. It made a huge difference. We also paid to have the yearly maintenance performed. At that time Chris was the technician who quoted us a price to have all the duct work re-done but we thought it was too much money to spend and decided to wait. Bringing us to the present day, Home Comfort had been calling us for several months telling us that we still had one free maintenance visit left that was already paid for. Unfortunately we were unable to make the time for the visit due to many medical problems my husband was facing and with many scheduled doctor appointments. Finally I convinced my husband to let us make an appointment as we were facing another hot and uncomfortable summer and the work needed to be done. At first I was not happy as the first appointment I had scheduled was cancelled and changed to later that week then they tried to cancel that appointment again. I got upset and said I wanted them to send someone even if it was late afternoon. I told my husband here we go again with yet another company that was going to give us the run around. We were pleasantly surprised when a young well-groomed, well mannered technician name John Ruiz showed up to do the inspection. He was very friendly but professional at all times. He checked everything out and then let us know what was needed. Even though he had already cleaned the unit outside he convinced my husband for us to sit down with him and take a look at what he had to offer in the way of a new unit. He thoroughly explained everything with pictures and helped us decide on a unit that best fit our needs as well as being affordable. He answered all our questions and to our surprise was even able to schedule us to have the new system installed the very next day. The installers showed up the next morning on time (Enrique Ceja and his nephew Enrique Ceja) (all in the family) ready to work. They were there 9 hours and I never saw them stop working except for a short lunch break. The Enrique Sr. was very knowledgeable and said he had been in the business for over 20 years. They did an excellent job and stayed make sure the system was working before leaving. John followed up with another visit on his way home several days later to check out the system and make sure we were satisfied with the work that had been done. He even took pictures up in the attic to show us the difference. Now I can honestly say we have a very comfortable flow of air coming from all the vents – even a little to cool at times, but we are very pleased. We would highly recommend Home Comfort USA to anyone looking for quality affordable work done by people that really care. Thank you John, both Enrique’s and Home Comfort for a Job Well Done! Sincerely, Beverly & Berry Dalton"

"After many roofing estimates that were incredibly high and came with either no financing or high interest financing, I stumbled upon Zen Builders. Simon was attentive, knowledgeable, and on top of his game. My roof was completed in three days, it's beautiful, and there were NO LEAKS when the rains came a few days later. The workers were professional, considerate, and the clean up was amazing. No trace of having construction in my yard. Because I was so happy with the work, I mentioned to Simon that I would love to have him come back and do a few more projects. I ended up with an even better financing option (both loans are well-within my budget) and a GORGEOUS new patio cover complete with a surprise ceiling fan in the middle! The patio is now white, and they painted the trim of my house to match. They also fixed my heating/AC ducts, insulated my attic, and for free, added plywood, so I can actually store items up there. I have never had an issue getting ahold of Simon or his sister, Kineret (Kerry). When there was an adjustment needed to the air ducts, the workers came out quickly (amid the COVID-19 quarantine) and simply fixed it! I couldn't ask for more! All work took less than a month to complete and I never felt pressured, ignored, or bamboozled. I have recommended Zen Builders to many of my friends. I hope they recover from the imposed quarantine to continue to provide excellent service."

"Zohar was suggested to us by a colleague for our kitchen and 2 bathrooms remodeling project and we are very thankful for that recommendation. Zohar was really easy to work with and extremely easy-going with us. We really valued how experienced Zohar is when it comes to all the tasks that were involved in the remodeling including where to shop for things such as tiles, vanities, faucets, light fixtures and how all the workers were willing to give their feedback in order to help us make the best decision for our house and budget. During our remodeling, Zohar gave us daily updates in regards to the progress and he even visited our house daily and even helped us with a non-related plumbing problem (a broken pipe that leaked into the wall of our laundry area). Zohar and his crew demolished our kitchen and bathrooms completely and turned it into our favorite spaces in the house. We highly recommend working with Zohar (Best Builders Group) for any type of remodeling project."

"Not only did the technician find what was wrong, he told me that the unit was in really good shape (after he got it running) and that it was good to go for many more years.  That's honesty for ya!  I know that IWAI is a little far from the westside of LA but I called Craig anyway because of the great job he did for another one of my clients.   The tech got out there within 48 hours and made some minor repairs to a unit that I was told would possibly need replacing.  My clients were thrilled at the low cost of the inspection and that it only needed a couple of parts to get it running like new.  They ended up buying the condo and are extremely happy.  But wait, there's more!  
(Second Job) I met Craig in January of 2015 when he came out to look at a heating problem in one of my client's apartment complexes in Beverly Hills.  This was an old building (1947) that had 3 gravity furnaces underneath the property.  All 3 were original and failing.  I got three bids to have them removed and replaced with new units.  One bid was just over $18,000, the other just over $16,000. Mind you, this was to remove three gravity furnaces, replace them with new gas furnaces, including some duct work, as well as do a complete new installation in the attic of the top floor unit.  IWAI's price came in approx. $8,000 cheaper than the highest bid!!! $8,000!!!!  I was skeptical at first.  I mean who wouldn't be?  An $8,000 difference?  But I discussed it with my client and we went with IWAI Heating and Cooling.  Not only did Craig do what he said he was going to do, but he started on the day he promised, and he finished on time as well!!!  The tenants had only nice things to say about he and his crew and no one was inconvenienced but for a couple of hours when an air return had to be installed in one of the lower units.  The job couldn't have gone any better and the price was outrageously inexpensive for the work that was performed.  My client was thrilled and so were her tenants, especially now that they had heat.  Thanks to Craig and his crew for taking care of this job with the upmost professionalism.  If you need anything regarding HVAC, call IWAI heating and cooling.  Have them come out and give you a quote; you'll be glad you did!!!

Boiler Repair FAQs, answered by experts

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

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 a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.
