My mother has a new air conditioning unit (similar to heat pump) that was installed by another company. Outside temperature yesterday was 96 degrees and the unit stopped working yesterday around noon. By the evening time, the house was 86 degrees which is dangerous for her as she is in her late 80's and homebound. I called the company who installed the unit and was told that it would be 3 weeks before they could come out even though the unit is still under their warranty. (Oddly enough that company also has "A" rating through Angie's List but I'm puzzled how that's possible.) The service coordinator was terse and said they only did "first come, first serve" which I understand when dealing with most of us. However there are times when priorities are needed.

I found Aire Serv on Angie's List. From the beginning of the call the experience was positive and very helpful. She acknowledged that home bound and elderly people needed to have a quicker response. She agreed to try to get someone out the next day and would try to get someone there today so would call me with more information ASAP. Meanwhile my husband attempted to problem solve the issue and fortunately managed to fix it. That is the only reason that Aire Serv did not do work for us. I will absolutely use Aire Serv the next time we need anything and highly recommen

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"Much better than expected - some slight delays waiting for parts, but for the most part a timely process from start to finish. Would like to complement the installers (Eric and Chance) for their knowledge, problem-solving skills, positive attitude, work ethic, and overall attention to detail."

"Product was what we needed. No pressure to buy. Come to the home, makes recomendations, and you have 3 days to turn down, if you rethink your acceptance. We even had a sale paper get us about $750 off after we accepted the terms and Sears honored this. Great way to save more. The Craftsmen did a very good job. The system was removed and new one installed in 5 hours. That was furnace and heat pump. Crew size was about 3-1/2. Very Pleased. Wife is real happy."

Install Boiler FAQs, answered by experts

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.
