"We hired AC Dave to install a heating & cooling unit, after using them for our old unit's maintenance for years. It was a unit that. went on the roof, so installation was no small task. They did a fantastic job, kept the area clean, were extremely courteous, and we felt like we were hiring family to help us out. They pulled all of the permits which cost extra of course, but it saved us the hassle of dealing with the city and handled the post work city inspections."

"I’m so glad I called HD mechanical to have my thermostat fixed. We set a time to meet up and he was there on time and very professional. He was very thorough with his work and explained to me all the work he performed. He even checked and serviced my unit, showing me that my filter needed to be changed. Would definitely recommend to anyone who needs and service/repairs done."

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

"I've been using Cal Climate for about three years and I couldn't be more satisfied with their responsiveness and professionalism. From the person who answers the phone and schedules appointments to the servicemen, they're always so nice to deal with. I always schedule a routine preventative service each May or June and this year Mike was my serviceman. He gave me an excellent explanation about how to choose a filter for my HVAC system that would enable it to work most efficiently and require fewer changes. The invoice for the service came through email with a mechanism to pay it online which made this the easiest home maintenance service I have had to deal with. Kudos to Cal Climate!"

I was in and out quick all fluids topped off, and potential problems brought to my attention, no sales pitch just good old fashioned honest people. We'll do business with them again.

"They were AWESOME. Same day service and quickly diagnosed the issue (blown transformer, since my furnace does not have a fuse). The guys were professional, courteous, explained what they were doing and why, and couldn't have been nicer. They finished the job quickly, and even installed the NEST which I had done wrong the first time, hence the need to call them. :-P"

"West Tech Mechanical Services (Joe Gonsalez) did an excellent job. This is the best investment that I have ever made for our quality of life in our home. Joe's attention to detail is evident in the care and consideration that he put into the duct work in the installation process. He thoroughly explained to me the importance of the duct work: location and size of the ducts to maximize the efficiency of the system that he was installing. Our home is an old home, and I really appreciate the care that he took in the installation process. I obtained 3 quotes for this job and West Tech Mechanical was in the middle. All the persons that came to our house were nice people. However, Joe's obvious attention to detail and how he explained the job is what convinced me that he and his company were the right people for the job. For a home owner that is considering the installation of a central air and heat system in their home or, any work for that matter on an existing heat and air system, I highly recommend this company as one that should be considered."

"Very positive experience with Andrew at DNA. He provided me multiple solutions to help correct our heating system issues given the age of our home. We ultimately replaced our unit and I have never seen more care taken by a contractor to help keep our home clean and free from dirt and dust. Every time DNA would enter my home they wear shoe covers; when they replaced the furnace they installed temporary plastic sheeting walls to isolate the mess from the install to a minimal area which they also cleaned after completion. As I mentioned, the cleanest contract work I have ever had. Additionally, very well mannered and great attitude. I would hire them again without shopping for quotes."

"This company was the second i had out to look at repairing our tankless hot water heater. For over a week the hot water would turn off randomly.  Baltica was my second opinion  for the repairs and i felt really lucky to have found them on Angie's list. The first company told me i needed to replace the entire 5 year old unit for $2200.00. Baltica answered all my questions before coming out,  Marius assessed the condition once  he came out,  the unit was flushed and clean out valves were installed he was very professional.  How nice to work with a company that stands behind their service.

Install Boiler questions, answered by experts

Most installations take 2-5 days, including old system removal and setup.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
